PR102 is a Mini-PLC designed to implement basic control systems for various applications such as lighting control, pumping control, ventilation and heating control, and others.

The key advantages of PR102 are its extensive functionality and high density of I/O points. Occupying only 126 mm of a DIN-rail length in a control cabinet, this Mini-PLC offers a total of 40 built-in digital and analog inputs and outputs and two RS485 ports for communication with Modbus-RTU/ASCII-enabled devices. Furthermore, the built-in I/Os may be directly expanded with up to two extension modules of the PRM series.

An application 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.

Functions and features

  • A total of 40 I/Os
  • 8 analog inputs, each capable of connecting:
    • RTD sensors (Pt500/1000, Ni500/1000, etc.)
    • NTC/PTC sensors
    • 4-20 mA / 0-10 V signals
    • Digital signals
  • 2 analog outputs configurable for 4-20 mA or 0-10 V
  • 2 RS485 interfaces
  • PRM-expandable: up to 32 additional I/O points over an internal bus with no loss in performance
  • Extended operation temperature range: -40…+55 ºС
  • USB-powered in the programming mode
  • Software-based features include: retain variables, day timer, week timer, PID control, etc.

Applications Include:
PR102 can be used in numerous applications such as building automation, lighting control, and access control systems, technical equipment such as pumps, fans, compressors, and presses to the conveyor and filling systems, etc.
