PR157s11 in DIN rail enclosure, front three-quarter view, with two rows of input terminals

12 isolated inputs via CAN bus

Article number PR157s11

The PR157s11 has twelve digital inputs and a potentiometer input. The inputs accept 24 V signals, each have their own plus and minus terminal and are optically isolated from the potentiometer input and the supply. The module runs on a 9 to 30 V DC supply.

Supply 9 to 30 V DC
Input 12 digital inputs of 24 V DC, 6.7 mA per input at 24 V; potentiometer input for 1 kΩ to 100 kΩ
Isolation digital inputs optically isolated from the potentiometer input and the supply

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.
