TLK94 Controller with universal input

New product
 
More info

TLK 94-A 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 function (FAST or OSCILLATING type), 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. 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 6 led. The instrument can have up to 5 outputs: relay type or to drive solid state relays type (SSR).

Features

  • 48x96 mm panel mount controller with dual display,
  • 1 probe input
  • up to 6 relay outputs or 2 analogue outputs and 4 relay outputs
  • Optionals: Current transformer input, 2 digital inputs and RS485 serial port
