TIK-PLC 991 controller

TIK-PLC 991 controller
Designed to register signals from external sensors with a digital RS-485 interface (up to 7 sensors without additional power supply), process them and transmit the received information to an external telemechanics and control system;

Performs the functions of a EPS, a power source for sensors and a safety barrier;

  • RS-485 digital input interface with intrinsically safe sensor power output;
  • оone output channel 4...20 mA;
  • digital interface RS-485;
  • intrinsically safe circuit power supply;
  • two relay outputs, one discrete input;
  • OLED display for displaying controller parameters and settings;
  • 3-color LED status of the controller;
  • 5-way joystick for menu navigation.
