© PHOENIX CONTACT - 2010-12-13102964_en_04 INTERFACE PSI-REP-RS485W2 Data sheet 1D e s c r i p t i o n The PSI-REP-RS485W2 DIN-rail mountable, modular RS-485 repeater is designed to meet the high requirements associated with the use of fieldbus systems. The device is snapped onto standard EN DIN rails in the control cabinet and supplied with 24 V DC. The main areas of application are: – Electrical isolation/bus segmentation – Increasing system availability – Increasing the range – Increasing transmission speeds – Extending the number of devices to n x 32 – Implementing hybrid/network structures – Modular star couplers The repeater can be used universally in all common 2-conductor bus systems (RS-485W2). The following features of the repeater are particularly outstanding: – Supports all bus systems with UART/NRZ data format and 10/11-bit character length – Transmission speed of 4.8 kbps to 500 kbps – Automatic transmit/receive changeover – Integrated, connectable termination resistors – High-quality 4-way isolation – 24 V DC control cabinet supply voltage – User-friendly connection via COMBICON plug-in screw terminals –B i t r e t i m i n g – Bit oversampling – Modular station structure, even with PSI-MOS-... fiber optic converters

1.1 Bit retiming

RS-485 signals with a bit distortion of up to 35% can be reliably detected using the bit retiming function and are converted to their original bit form before being transferred to the next segment. This data processing function means that a virtually unlimited number of repeaters can be aligned without an impermissible level of bit distortion.

1.2 Bit oversampling

The bit oversampling function can be used to detect and filter malfunctions so that they are not transferred to the next segment.

5 Applications

The PSI-REP-RS485W2 repeater can be used to create network topologies that are perfectly adapted to the relevant application. The limits set by standard RS-485, which specifies the electrical properties of bus interfaces, are thus extended. Standard RS-485 defines the following basic specifications: – Maximum of 32 devices per potential segment – Only (linear) bus structure permitted – Maximum bus cable length of 1200 m – Maximum branch line length of 5 m without termination resistor – Bus cable termination only at the start and end of the bus cable Example applications for repeaters A segment can be created as an active branch, which can comprise the full bus cable length and a maximum of 31 devices. Electrical isolation and bus segmentation using repeaters enables the permissible bus cable length to be multiplied and the number of devices to be extended to n x 32, since the total number of devices of the RS-485 specification applies in each potential segment. The repeater supports higher transmission speeds by subdividing into shorter segment lengths. Hybrid/network structures, star, and tree structures can be created using the PSI-REP-RS485W2 modular repeater. A freely selectable installation concept, independent of the restrictive linear structure, is thus possible. Repeaters can be combined to create modular star couplers and this type of star coupler can be extended with PSI-MOS-RS485W2... FO converters to create RS-485 2-conductor systems.

8 Connection notes

• Install the device on a 35-mm DIN rail according to D I NE N6 0 7 1 5 . To avoid contact resistance only use clean, corrosion- free DIN rails.
• End clamps can be mounted on both sides of the device to stop the devices from slipping on the DIN rail (for ordering data see Page 2).

8.1 Combined assembly with a system power

supply unit (modular star coupler)

• Connect together the required number of DIN rail connectors for the connection station. Two DIN rail connectors are required for each device (see A in Figure 5). A maximum of ten devices are permitted in a connection station.
• Push the connected DIN rail connectors onto the DIN rail (B and C).
• Place the device onto the DIN rail from above. The upper holding keyway of the device must be hooked onto the top edge of the DIN rail (see Figure 6). Make sure that it is aligned correctly with the DIN rail connectors.
• Once the device has been snapped on properly, check that it is fixed securely on the DIN rail. Figure 5 Combined assembly WARNING: Only mount and remove devices when the power supply is disconnected. WARNING: The PSI-REP-RS485W2 module is designed for SELV operation according to IEC 60950/EN 60950/VDE 0805. The module may only be connected to devices which meet the requirements of EN 60950. WARNING: Connect the DIN rail to protective earth ground with a grounding terminal block. The devices are grounded when they are snapped onto the DIN rail (installation according to PELV). This ensures that the shielding is effective. Connect to protective earth ground with low impedance. A BC 101973A003

9 Cabling notes

9.1 Connecting the supply voltage

Operation as an individual device Supply the supply voltage to the module via terminal blocks 1 (24 V) and 2 (0 V). Figure 7 Individual/redundant supply Operation in a star coupler topology When the devices are operated in a star coupler topology, the supply voltage must only be supplied to the first device in the station. The remaining devices are supplied via the DIN rail connector. A redundant supply concept can be created by connecting a second power supply unit to another device in the topology. Using the MINI POWER system power supply unit As an alternative, the star coupler topology can also be supplied using the MINI-SYS-PS 100-240AC/24DC/1.5 (Order No. 2866983) or MINI-PS-100-240AC/24DC/1.5/EX (Order No. 2866653) system power supply unit. It is connected via two DIN rail connectors. Usually the system power supply unit is mounted as the first device in a topology. A second power supply unit can be used to create a redundant supply concept.

9.2 Connecting th e data cables
