14.1 External relay module/logic module ER8/EL8
By using the external relay module ER8 or logic module EL8, the controller can
be expanded by eight relay outputs (changeover contacts) or logic outputs (0/
12 V). Communication with the controller occurs via the RS422/485 interface.
All controller signals for switching outputs can be output by the module.
Configuration is only possible through the setup program.
v Section 7.4 “Outputs”
Connection The electrical connection is carried out like the connection to an RS485 inter-
face (the figure below shows ER8; see also
Operating Manual ER8/EL8,
B703564
).
Configuring
the module
h Activate the relay module via the setup program
Edit r Settings only via setup r Expanded configuration
This activates the menu Edit r External relay module.
h Configure the module
The functions are related to the relay module, but they also apply to the
logic module (Off = 0 V; On = 12 V).
H
If the module ER8/EL8 is connected to the interface, then no further
communication is possible via the interface.

If the setup plug is connected to the profile controller, the module will
not be operated and the outputs are in idle position (logic outputs:
0V).
