Inputs and outputs
There is a list of input and outputs in
Appendix C Input and output lists
that can be used to help you keep
track of which inputs and outputs you need to configure.
Analog inputs
Analog inputs must refer to an
Agnd
terminal.
Analog inputs can, depending on the configuration, be used for either PT1000 / Ni1000 temperature sensors
or for 0…10 V DC analog input signals, for example from a pressure transmitter.
Digital inputs
Digital inputs must refer to
+C
on terminal 4. Digital inputs may only be wired to voltage-free contacts. Any
external voltage applied to a digital input may harm the unit.
Universal inputs
A universal input can be configured to act as either an analog input or as a digital input.
A universal input configured as an analog input can, depending on the configuration, be used for either
PT1000 / Ni1000 temperature sensors or for 0…10 V DC analog input signals, for example from a pressure
transmitter.
