Description of the PID temperature controller

The model CS4S is a compact digital PID temperature controller for the display, control and monitoring of temperature.

The PID temperature controller features a multi-function input, meaning the configuration of the sensor input can be set. Thus the flexibility of the controller is considerably increased, and stock-holding is made easier. An alarm output for monitoring the actual value is also available as standard.

The control parameters of the PID temperature controller can be set across broad ranges. Auto-tuning, which facilitates finding the optimal control parameters, can be activated.


The PID temperature controllers are designed for installation in a control panel. The control output can be set either as relay (for slow control), as logic for the control of electronic solid-state relays´ (for fast control and high current loads) or as a continuous 4 ... 20 mA output.

As options, there is a 2nd alarm output available for the monitoring of the actual value and the control loop, and a heater break alarm for monitoring the control output, or, alternatively, a 2nd relay output. Likewise, an RS-485 serial interface or a parameter memory for a 2nd set point is available. The parameter memory can be selected via an external connection terminal.
