8.12 Versions with integrated supply voltage
The supply voltage can be used only for energization of a 2-wire transmitter or for energization of
max. 4 control inputs. The supply voltage is potential-free and can also be used for energizing inputs
INP3 ... INP6 or for other units. Selection of supply voltage or digital inputs is by S.I.L. switches (see
figure opposite).

The supply voltage is only applied to terminals A12 and A14 with INP1 configured for
current or thermocouple (C.200; type) and the S.I.L. switches set for transmitter supply
(factory setting)! With the S.I.L. switches set to digital input, the voltage is applied to
terminals A1 and A4 independent of the configuration of input INP1. In this case, the voltage
input of INP5 is not available.
