1 Description

The housings of the ME-IO 18,8... product range consist of a 18.8 mm wide lower housing part with space for the PCB assembly. The lower housing part can be combined with various hous- ing covers. The lower housing part is subdivided into 9 units (1 Unit = 11 mm). These units can be combined with con- nectors and housing covers in various ways. The connectors correspond to a unit and have a push-in connection. There are 4-pos. connectors for conductor cross sections of up to 2.5 mm 2, and 6-pos. connectors for conductor cross sections of up to 1.5 mm2. Partially assem- bled or TWIN variants are also available. All in all, the 4-pos. connectors allow for a maximum of 36 positions in a single housing. The 6-pos. connectors even allow for up to 54 po- sitions. As a counter-part to the connectors, there are head- ers in 2 or 3 unit versions for soldering onto the PCB. The housing covers in 2 to 7 unit versions are especially suited for installing connection systems such as USB or D-SUB as well as display and operating elements. We would be glad to install the required openings for you. The housings can be snapped onto an NS 35 DIN rail. It is possible to use the housings with a DIN rail connector by means of which communication can be established be- tween the housings, or the supply voltage can be transmit- ted. The 3D housing data can be found at phoenixcontact.net/products. Make sure you always use the latest documentation. It can be downloaded at phoenixcontact.net/products.

The orange lever of the Lock and Release system is used for locking and unlocking the push-in connectors. The push-in connectors are available in three variants, fully and partially assembled, and as a TWIN connector, on which two positions are each bridged together. The counter-part to the push-in connectors are the headers. The housing can be optionally combined with a DIN rail con- nector by means of which data or the power supply can be transmitted from module to module.

5 Combination of headers and connectors

5.1 Connections of headers and connectors

5.2 Selecting headers and connectors

The connectors correspond to a unit. For the connectors there are matching headers in 2 or 3 units for soldering onto the PCB. Figure 3 1U connector and 2U + 3U headers (5 mm pitch) Figure 4 1U connector and 2U + 3U headers (3.45 mm pitch) ince the connectors are available different variants, the con- nectors have to be suitable for the headers. For the partially assembled connector with two 1U/20 connections, you also have to pay attention to the position in the header. You can also code the connectors so that they are not con- nected incorrectly by accident (see “Coding the connectors” on page 23).

5.3 Concatenating headers

The headers must be concatenated in a way that makes it possible to attach the Lock and Release system, which is available in different lengths (3U – 9U). The headers have guide pins, which have to fit into the re- cesses of the Lock and Release system. Figure 5 Guide pin and Lock and Release system The housing is designed for 9 units. The headers can only be concatenated at certain positions. In doing so, it is impor- tant to pay attention to the combination of the headers so that the guide pins fit into the Lock and Release system. It is therefore not possible to concatenate the 3U headers di- rectly because the guide pins will then no longer fit into the Lock and Release system. For the same reason, 2U head- ers must always be placed in front of the 3U headers, e.g. the 2U on position 1 + 2 and the 3U header on positions 3 - 5. In addition to the headers, housing covers can also be equipped, which are available in 2 to 7 unit versions. Their position can be chosen freely. Possible positions of 3U headers Figure 6 Possible position and combination of In Figure 6 the possible positions of the 3U headers are dis- played. It shows that a direct concatenation of 3U headers is not possible. In front of the 3U headers it is possible to concatenate 2U headers; housing covers are equipped before and between them. Possible positions of 2U headers Figure 7 Possible positions and combinations of The 2U headers can also be directly concatenated. Figure 7 shows all possible positions. You can use the different vari- ants of the 2U header for this purpose. 3U headers fit to some extent on the unoccupied positions behind the 2U headers (see Figure 5 and Figure 6). In addi- tion, housing covers can be equipped. When doing so, make sure that there are no 1U housing covers. 3U3U

8.5 DIN rail connector

It is possible to combine the housings with a DIN rail con- nector (TBUS) by means of which data or the power supply can be transmitted from module to module. The DIN rail connector is simply laid into the DIN rail NS 35/7.5 and the housing is snapped onto it. This concept allows complete individual devices to be re- moved from the group without interrupting the contact chain. In addition, the DIN rail connector is compatible with the ME-MAX and ME-TBUS housing ranges.

9 Mounting the housing

9.1 Assembling the Lock and Release system

When the PCB is completely assembled, the orange Lock and Release system, included in the scope of delivery of the lower housing part, has to be assembled. To do this, proceed as follows:

• Solder the header onto the PCB. Figure 41 Attaching the Lock and Release system
• Attach the orange Lock and Release system onto the header. The recesses of the Lock and Release system have to fit over the protruding guide pins of the header. Press the Lock and Release system against the header. Figure 42 Attaching the spring
• Attach the spring which is included in the scope of de- livery. The spring is inserted at one of the possible posi- tions.

9.2 Inserting the PCB

Figure 43 Inserting the PCB

• Insert the PCB into the guide slot of the housing and push it downwards until it audibly snaps in. Pay attention to the positioning of the connectors and the headers (see page 6).

ME-IO 18,8... 105787_en_02 PHOENIX CONTACT 22 / 27

9.3 Assembling the housing covers

Figure 44 Attaching the housing cover

• Attach the housing covers if they are equipped. The housing cover has two snap-in hooks on one side and only one on the other side. The side with the two snap-in hooks has to be facing the base latch. Make sure that the concealed side guides are also snapped in. To do so, it helps if you lightly push the sides of the housing together.

9.4 Assembling the connectors

Figure 45 Inserting the connectors

• Insert the connectors. The connectors only fit onto certain headers and can also be coded. Each connector has an engraved arrow that has to be facing the base latch.

ME-IO 18,8... 105787_en_02 PHOENIX CONTACT 23 / 27

9.5 Releasing the connectors (Lock and Release)

Figure 46 Releasing the connectors

• Insert a screwdriver through the opening of the Lock and Release system.
• Hook the tip of the screwdriver into the base latch.
• Pull the screwdriver forward to release the Lock and Release system. The connectors are lifted and the contact is released. But the connectors do not fall out. The housing cover remains in its position.

9.6 Coding the connectors

Figure 47 Coding the connectors (pitch 5 mm) Figure 48 Coding the connectors (pitch 3.45 mm) You can code the connectors and the headers in order to prevent them from being connected incorrectly by accident. Each connector has for four or five positions for attaching coding plates. Use the coding profile CP-DMC 1,5-THR NAT, 1790647.

• Insert a coding plate at the correct position and twist it off the pentagonal holder. WARNING: Electric shock Make sure that the module is free of current. SZS 0,6X3,5 VDE 1212602

9.7 Connecting conductors (push-in connection)

• Insert the stripped wire into the round opening of the ter- minal block without using a tool. Wires with a smaller cross section or stranded con- ductors without ferrule
• Push in the pushbutton with a screwdriver to open the spring. Disconnecting
• Push in the pushbutton with a screwdriver to release.
• Pull out the conductor. We recommend using a bladed screwdriver SZS 0.4X2.5 VDE, 1205037.

9.8 Mounting the housing on a DIN rail

Figure 49 Snapping the housing onto the DIN rail Assembly

• If you use a DIN rail connector, then lay it into the DIN rail with the protruding connector side facing left.
• Place the device onto a grounded 35 mm DIN rail from above so that the upper housing slot hooks onto the top edge of the DIN rail.
• Press the device carefully at the top of the housing to- wards the mounting surface.
• Once the snap-on foot has audibly snapped onto the DIN rail, check whether it is securely attached.

• Then pull off the base latch. Figure 53 PCB with indentation

10.4 Taking out the PCB

Figure 54 Taking out the PCB

• On the bottom of the housing there are two openings at the outermost ends. Release the catch mechanism there using a screwdriver. Keep both catch mecha- nisms open.
• To remove the PCB, you have to slightly bend the hous- ing wall up while pulling the Lock and Release system forward at the same time.
• Pull the PCB out. To enable faster PCB removal, the hole on the left-side can alternatively be an indentation in the edge of the PCB. It would then not be necessary to remove the base latch before removal (see “Maximum PCB dimensions in the lower housing part” on page 9).
