The PMA KS 41-1 temperature controller is designed for universal, precise, and cost-effective control tasks in various industries. It offers simple 2-point (on/off) control, continuous PID control, or 3-point stepping control. The process value signal connects via a universal input, and a supplementary analog input can be used for heating current measurement or as an external setpoint input. The KS 41-1 features three process outputs, which can be configured as 3 relays or 2 relays plus a universal output. This universal output can operate a solid-state relay, provide a continuous current/voltage output, or energize a two-wire transmitter. This controller is particularly well-suited for applications in furnaces and ovens, burners and boilers, plastics processing, and driers. It has a horizontal form factor, measuring 48 mm high and 96 mm wide. Additional features include a BluePort front interface, BlueControl software, maintenance manager, error list, automatic/manual key, monitoring of heating current and input circuit, timer and programmer, and extended limit signaling function with latch. It is type tested to EN 14597 (replacing DIN 3440), cULus, and GL.
