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.
