Temperature controllers keep heaters, ovens and processes at the set temperature, reading a thermocouple or RTD and driving a contactor or solid state relay. Fotek controllers are a familiar sight on plastic machines, sealers and ovens across Pakistan.
The NT series is the current PID controller range, in panel sizes from 48×48 mm (NT-48) to 96×96 mm (NT-96), with relay (R), voltage-pulse (V) for SSRs, or linear 4–20 mA (L) control outputs and alarm outputs. The MT series offers the same outputs in a classic design. The TC series covers simpler on/off and analogue-setting controllers.
The output letter matters: use V with an SSR for fast heater control, R for contactors, L for valves and power regulators. Send the panel cut-out size, sensor type and output you need, or the code of your old controller.
