Universal controller type KS40-1

Application and function

The universal temperature controller KS40-1 are intended for universal, precise and cost-effectiv control tasks in all branches of industry. For this, the unit 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.

Every KS 40-1 has three process outputs that can be 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.

Plug-in module

The KS 40-1 controller is built as plug-in module. This enables it to be replaced very quickly without tools, and without disturbing the wiring.


During start-up, the self-tuning funktion determines the optimum settings for fast line-out without overshoot.

With three-point controller configuration, the "cooling" parameters are determined separately, thus ensuring an optimum match to the process.

Display and operation

Clear informations are given by ten indicator LED's in the front panel that display operating mode, I/O states, and errors. The auto/manual key switches the controller into the manual mode directly, without lengthy operating sequences. If required, the direct switch over can be disabled or the key can be configured e.g. to start the internal timer. This results in a level of operational safety that is usually found only in controllers of a higher price category.

Front interface and Engineering Tools

Control parameter adjustment in seconds has now also been implemented in the KS 40 class of instruments.

Via BlueControl software incl. its simulation functions, and especially the convenient BluePort front panel interface, the required set-up for a specific control task can be determined without a detailed study of the operating instructions.

Off cause almost all adjustments can be done comfortably over the instrument front.

Password protection

If required, access to the various operating levels can be protected with a password. Similarly, access to a complete

level can be blocked.
