Model CS4R is a compact digital temperature controller for displaying, controlling and monitoring temperatures.

The controller has a multi-function input, i. e. the input configuration is adjustable.

Thereby the flexibility of the controller is significantly increased, stock-keeping is simplified.

An alarm output for process value and control loop monitoring is also available as standard.

The control parameters can be set over wide ranges.

An auto-tuning function can be activated, which makes it easier to find the ideal control parameters.

The controllers are designed for rail mounting.

The control output is alternatively equipped with a relay (for slow controls), with a logic level to drive a solid state relay (for fast controls and high current loads) or with an analogue current signal 4 ... 20 mA.

The versions with control output 4 ... 20 mA can be reconfigured and used as transmitter with output signal 4 ... 20 mA.

Optionally available are a heater burnout alarm for heat current monitoring and a serial interface RS-485.
