Multi-Temperature-Controller KS 800

5.6 Input circuit examples

5.7 Digital inputs

KS 800 contains 4 digital inputs, which can also be configured individually as inputs, unless requi-

red as controller outputs (cooling output with three-point controllers or closed output with three-point

stepping controllers).

The inputs are "high-active" and designed as current sink according to IEC 1131 type 1. The current

requirement is approx. 5 mA.

Logic "0" = -3...5 V

Logic "1" = 15...30 V

With configuration as input, the following allocation is applicable:

IN/OUT13: control parameter set 1/2 switch-over

This input is used to activate the 2nd control parameter set in common with all con-

trollers which are configured accordingly.

IN/OUT14: controller switch-off

This input is used for common switch-over of all controllers configured accordingly to

manual mode and for setting the outputs to "0". All other configured functions

continue operating normally.

See also hint on page 21.

IN/OUT15: Input for leakage current monitoring

The logic signal of an external leakage current monitor can be connected to this

input.

IN/OUT16: W/W2 switch-over

This input is used for activating the 2nd setpoint (W2) with all controllers configured

accordingly.

Unused digital inputs need not be connected.
