TLK42 Temperature controller with universal input

New product
 
More info

TLK 42 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’s 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 display, the Set value is visualized on 4 green display while the outputs state is indicated by 4 led. The instrument provides for the storage of 4 Set Points and can have up to 4 outputs: relay type or can drive solid state relays type (SSR).

Features

  • 48x48 mm panel mount controller with dual display,
  • 1 probe input
  • Up to 4 relay outputs
  • Optionals: Current transformer input and RS485 serial port
