Inputs

(The complete KS 816 connecting diagram is given in section 7.).

Illustrations with connecting examples are given in section 5.6.

For all inputs, the following rules are applicable:

Unused inputs must be short-circuited!

Thermocouples and DC voltage:
Terminal + and - of an input must be connected.

Resistance thermometer:
Configure unused controllers as for thermocouples or voltage. Shortcircuit
the + and - terminal of an input.

The inputs of channel 1...16 are the process value inputs of individual channels and
can be configured for thermocouple, resistance thermometer or voltage.
Within an instrument, "mixed operation" of inputs is possible.
Accordingly, each individual channel can be configured freely for controller (conti-
nuous, 2- or 3-wire) or for transmitter (0...20mA or 4...20mA) operation.

5.1 Thermocouple inputs (IN1+/IN1- ... IN16+/IN16-)

The following thermocouple types to DIN/EN 60584 can be connected:

The upper measuring limit of KS 816 is defined by the upper temperature limit of
the thermocouple type. The thermocouples are monitored for wrong polarity and
break. The action can be configured (upscale/downscale).

All thermocouples must be connected with correct polarity to terminals INx+ and
INx-.
With thermocouples to DIN 43710, the plus arm is red and the minus arm corre-
sponds to the thermocouple colour.
Acc. to DIN/IEC 584, the plus arm has the colour of the thermocouple type and the
minus arm is white.

Connections INxPt remain free.
