Product Description
    Details

    PR103 is a Mini-PLC with extended communication capabilities thanks to its Ethernet port and two RS485 interfaces as well as both Modbus TCP and Modbus RTU/ASCII protocols. While communicating via Modbus RTU/ASCII over the RS485 interfaces on the field/control level, PR103 can use the Ethernet port and Modbus TCP to ‘bridge’ data to the supervisory level of the automation pyramid.

    The PR103 Mini-PLC is equipped with 10 digital inputs, 8 digital outputs, 6 analog inputs, and 2 analog outputs. Moreover, 4 of 10 digital inputs can be used as pulse counters processing signals from 100-kHz encoders. Concerning the analog inputs, they are configurable and can operate with a wide range of RTDs, NTC/PTC, as well as with standard linear signals of 4-20 mA or 0-10 V. Furthermore, the built-in I/Os may be directly expanded with up to two extension modules of the PRM series.

    Thanks to built-in flash memory, the logging of, e.g. values on analog inputs/outputs, pulse counters, device status, etc., is possible. The file is stored in the CSV format, which allows its running in almost any spreadsheet editor, for example, Excel.

    Designed for installation on a DIN rail in a control cabinet, PR103 can operate in non-heated environments down to -40°C as well as in heated ones in temperatures up to +55°C.

    A user program is written in function block format in the akYtec ALP programming software available free of charge. The control algorithm is uploaded to the device memory via a micro-USB-cable connection.
