Optional open collector output* (NPN Transistor):

98 Collector

99 Emitter

Note!

The opening and closing function (= activation and deactivation of the relay coil or the open collec-

tor output) in case of a limit value can be defined in the set-up “Set-up - Signal settings - Digital

outputs (Relay / OC)”

Optional digital inputs on power supply board:

Optional auxiliary voltage output on power supply board for digital inputs (galvanically isolated from

the system, short-circuit proof, not stabilised):

+ Auxiliary voltage typ. approx. +24 V / max. 100 mA

- Auxiliary voltage ground

Note!

If the auxiliary voltage is to be used for the digital inputs on the digital boards (slots 1 or 2), the “-

” terminal on the auxiliary voltage must be connected to the “-” terminal on the digital boards for

potential equalisation.

4.2.2 Multifunction input boards 1 and 2 (on slot 1 or 2)

Analogue inputs:

The first digit (x) of the three-digit terminal number corresponds to the associated channel (1.. to

8..: channels 1 to 8, or A.. to H..: channels 9 to 16).

91 Digital input 1

92 Digital input 2

93 Digital input 3
