Connection of Inputs and Outputs
3.1
Overview of Inputs and Outputs
The image below shows the inputs and outputs on a double module. On a single module, only the inputs and
outputs on the left are available:
IN1–20
are voltage-free contact inputs. Each input has its own GND.
C1–8
are voltage-free relay contact outputs. Each output has a common terminal (C1–C8) and both a normal
open (NO1–NO8) and normal closed (NC1–NC8) terminal. Use the appropriate terminal for each output. Do not
use both NO and NC terminals for the same output.
The connectors labelled
N.U.
are not used.

Input Circuits
Below are the NEOL, SEOL, and DEOL configurations for the inputs. For correct operation, you also have to
indicate the used input circuit configuration in the XO client software. For more information, see the
XO Client
Software User Manual
(21796).
Normally open – NEOL
Short circuit = alarm
Open circuit = idle
(Default setting)
Normally open – SEOL
Short circuit = alarm
1K1 = idle
Open circuit = tamper
Normally closed – NEOL
Short circuit = idle
Open circuit = alarm
Normally closed – SEOL
Short circuit = tamper
1K1 = idle
Open circuit = alarm
Normally open – DEOL
Short circuit = tamper
1K1 = alarm
3K3 = idle
Open circuit = tamper
Normally closed – DEOL
Short circuit = tamper
1K1 = idle
3K3 = alarm
Open circuit = tamper
