PMA KS 50-1 Temperature Controller. The universal KS 50-1 temperature controller is intended for precise and cost-effective control tasks. The instrument provides simple 2-point (on/off) control, continuous PID control, or 3-point stepping control. The process value signal is connected via a universal input. A supplementary analog input can be used for heating current measurement or as an external set-point input. The KS 50-1 has three process outputs that can be configured as 3 relays or 2 relays plus a universal output. This universal output can be used for operating a solid-state relay, a continuous current/voltage output, or to energize a two-wire transmitter. Optionally, there are two additional optocoupler outputs that can be used freely. The controller is suitable for a number of industry applications including furnaces and ovens, burners and boilers, plastics processing, hot runners, driers, climatic chambers, and heat treatment plants. It features a universal continuous/switching version, reduced stocks, a 100 ms cycle time suitable for fast control loops, and a 20 ms shortest pulse for very fast/strong actuators. The analog output is freely configurable, and customer-specific linearization is available for all sensors. Settings can be blocked via password and internal switch for high security. The extended temperature range up to 60 °C allows mounting close to the process. It offers easy 2-point or offset measurement correction, emergency operation after sensor break by means of the "output hold" function, and logical combination of digital outputs for general alarm. The programmer includes 10 segments and an "end" signal. It also features an RS 422/485 Modbus RTU interface, built-in transmitter power supply, and a splash-water proof front (IP65).
