PR103 mini-PLC
The PR103 is a mini-PLC with advanced communication capabilities thanks to its Ethernet port and two RS485 interfaces, as well as Modbus TCP and Modbus RTU/ASCII protocols. By communicating via RS485 interfaces at the field level, the small PLC PR103 can use the Ethernet port and Modbus TCP protocol to transmit data to the control level of the automation pyramid.
The compact PLC PR103 modifications feature 10 digital inputs, up to 10 digital outputs, 6 analog inputs and a modification with 2 analog outputs and no analog outputs. In addition, 4 of the 10 digital inputs can be used as pulse counters that process signals from 100-kilohertz encoders. As for the analog inputs, they are configurable and can handle a wide range of RTD, NTC/PTC, and standard 4-20mA or 0-10V line signals. In addition, the built-in I/O can be directly expanded using two PRM series expansion modules.
