C Series Fuzzy + PID Temperature/Process Controller (22.5 x 96 x 83mm)

Product Code: R22

DIN Rail Mount: 22.5mm (W) x 96mm (H) x 83mm (D), 2 event inputs.

The new generation, low cost, PID microprocessor-based with Fuzzy logic controller series incorporate two bright, easy to read LCD displays which indicate Process value (PV) and Set Point value (SV).

The Fuzzy Logic technology incorporated on this series of controllers enables a process to reach the predetermined set point in the shortest time with minimum of overshoot during Start up (Power ON) or external load disturbances.

A wide range of inputs including Thermocouple (13 types), RTD, Milliamps (mA) and Voltage (V) are supported.

Configuration software available to download. Other accessories also available.
