TLK41 Controller with universal input


TLK 41 is a "single loop" digital microprocessor-based controller, with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual action (direct and reverse) control and with AUTO-TUNING FAST function, SELF-TUNING function and automatic calculation of the FUZZY OVERSHOOT CONTROL parameter for PID control. The PID control has a particular algorithm with TWO DEGREES OF FREEDOM that optimises the instrument features independently in the event of process disturbance and Set Point variations. Furthermore, the instrument allows for RS485 serial communication using MODBUS-RTU communication protocol and a transmission speed up to 38.400 baud. The process value is visualized on 4 red displays, while the output status is displayed by 4 LED indicators. The instrument has also a programmable 3 LED shift index. The instrument can store 4 Set Points and can have up to 4 outputs: relay type or Voltage type to drive solid state relays (SSR).


  • 48x48 mm panel mount controller with single display,
