8 isolated inputs and 8 relay outputs via CAN bus
Article number PR157s08
The PR157s08 combines eight digital inputs, a potentiometer input and eight relay outputs on one DIN rail module. The inputs accept 24 V signals, each have their own plus and minus terminal and are optically isolated from the outputs, the potentiometer input and the supply. The relay outputs are galvanically isolated from the supply and the inputs and switch up to 24 V DC and 5 A.
- Supply 24 V DC
- Input 8 digital inputs of 24 V DC, 6.7 mA per input at 24 V; potentiometer input for 1 kΩ to 100 kΩ
- Output 8 relays, each with NO, COM and NC terminal; 24 V DC, 5 A DC max.

Connections
| Terminal | Function |
|---|---|
| Terminal +24V | Supply plus |
| Terminal -24V | Supply minus (0 V) |
| Terminal CAN SCR | CAN bus cable shield |
| Terminal CANL | CAN bus low |
| Terminal CANH | CAN bus high |
| Terminal IN1+ – IN8+ | Plus of input 1 to 8 (+24 V of the input signal) |
| Terminal IN1- – IN8- | Minus of input 1 to 8 |
| Terminal SCR | Potentiometer minus |
| Terminal Signal | Potentiometer signal (wiper) |
| Terminal PP | Potentiometer plus |
| Terminal OUT1 NC – OUT8 NC | Normally closed contact (NC) of output 1 to 8 |
| Terminal OUT1 COM – OUT8 COM | Common contact (COM) of output 1 to 8 |
| Terminal OUT1 NO – OUT8 NO | Normally open contact (NO) of output 1 to 8 |
Setup
- Connect the module according to the terminal table.
- If the module sits at one end of the CAN bus network, fit jumper JP1: it terminates the bus with 120 Ω. Both ends of the network must be terminated like this.
PR157 series: I/O and communication modules for DIN rail
The PR157 series consists of DIN rail modules. The CAN bus versions read optically isolated 24 V inputs and a potentiometer, or switch relay outputs (24 V DC, 5 A) with separate NO, COM and NC terminals per output; status LEDs show the state of each input or output. Terminate both ends of the CAN bus network with 120 Ω: fit jumper JP1 on the module at the end of the network. More inputs or outputs, or control via RS485 and Modbus instead of CAN bus, are available on request for these versions.
