The USB-PDISO8 Series offers eight isolated AC or DC inputs and eight electro - mechanical relays in a single digital I/O system. The USB-ERB Series enables a PC or laptop to control eight to 24 electromechanical relays. The USB-SSR Series can monitor and control eight to 24 standard size solid state relay (SSR) I/O modules (relays sold separately). All devices in these series come in a heavy-duty metal enclosure with integrated mounting slots, which ensures that the devices are rugged enough for any DAQ application.

Measurement Computing (508) 946-5100 2 info@mccdaq.com mccdaq.com USB DIO High Voltage and Relay USB-SSR Series devices have an onboard switch to configure each module group for either input or output. Devices are shipped with all modules configured for output. Input and output modules cannot be mixed within a group. Positive and negative relay contacts are brought out to screw terminals for field wiring connections. Relay Configuration Switche USB-ERB/USB-SSR Series Only USB-SSR Series and USB-ERB Series devices have two onboard switches for configuringthe relay logic polarity and output relay power-up state for each relay bank/SSR module group. The cur- rent configurationof each switch can be read back with software. Devices are shipped with all relay banks/module groups confi- ured for non-inverted logic and pull-up (relays/modules inactive on power-up). Differential Isolated Digital Inputs USB-PDISO8 Series Only All eight inputs on USB-PDISO8 Series devices can be driven by either AC (50 Hz to 1000 Hz) or DC voltage, and can be read back as a single byte. Each input has a software-selectable filter with a time constant of 5 ms (200 Hz). The filter is required for AC inputs, and recom- mended for most DC inputs. Each module group can be set to either input or output (default). Input and output modules cannot be mixed within a group. Up to eight optically isolated (500 V) digital input connec - tion pairs are available from the signal I/O connector on USB-PDISO8 Series devices. Each signal is applied to a bridge rectifier so that the input is not polarity-sensitive. External Power USB-PDISO8 Series devices require between 6.5 V and 12.5 V of external power. USB-SSR Series and USB-ERB Series devices require between 6.0 V and 12.5 V of external power. An external power connection using the included external power supply is required to activate relays and SSR modules, and to run tests in software.

  • USB-PDISO8 Series devices, USB-SSR Series devices, and the USB-ERB08 are powered by a 9 V , 1.67 A external power supply (CB-PWR-9) that ships with each device.
  • The USB-ERB24 is powered by an external 9 V , 3 A regu- lated power supply (CB-PWR-9V3A) that ships with the device. Daisy Chaining Multiple Devices MCC high-voltage/relay DIO devices can be optionally daisy chained to connect to the USB bus through the high-speed hub on the host device. Up to four MCC USB devices can be daisy chained to a single USB port on the PC using the standard/ included USB cables. Make sure adequate power is provided to each connected device. You can use an independent power supply for each device, or connect a user-supplied custom cable to daisy chain power. Voltage Drop A drop in voltage occurs with each device connected in a daisy chain configuration.The voltage drop between the power supply input and the daisy chain output is 0.5 V maximum. Factor in this voltage drop when configuringa daisy chain system to ensure that at least 6.0 VDC is provided to the last device in the chain. Supply Current The following devices may require addition external power adapters depending on the number of connected devices: Device External Power Consumption (All Relays/SSR Modules On) USB-PDISO8 Series Draws 820 mA from the 1.67 A supply USB-ERB08 Draws 750 mA from the 1.67 A supply USB-ERB24 Draws 1.5 A from 3 A supply USB-SSR24 Draws 800 mA from the 1.67 A supply USB-SSR08 Draws 300 mA from the 1.67 A supply Some devices may require their own external power supply in a daisy chain configuration If unsure as to how much current an application requires, MCC recommends providing separate power to each connected device.
