Siemens SIMATIC NET SCALANCE XM-408-8C - Signaling Contact

6.4 Signaling contact
Information on the signaling contact
• The signaling contact is a 󹪞oating switch that signals error statuses by opening the contact.
The signaling contact must be operated within the range of the operating voltage.
If an error/fault occurs, the signaling contact opens. In normal operation, the signaling
contact is closed.
• The signaling contact is connected using a 2-pin plug-in terminal block (spring-loaded
terminal). The terminal block ships with the device and can also be ordered as a spare part.
• To wire up the signaling contact, use a copper cable of category 18-12 AWG or a cable with
a cross-section of 0.75 to 2.5 mm

.
NOTICE
Damage due to voltage being too high
The signaling contact can be subjected to a maximum load of 100 mA (safety extra‑low voltage
SELV, 24 VDC).
Higher voltages or currents can damage the device!
