Overview
Contact modules
Contact modules are used to switch circuits. The mechanical motion of the actuator is
converted to electrical signals in interaction with the contact module when contacts are
opened or closed.
The following variants of contact module are available:
● Spring-loaded terminals
● Screw terminals
● Front plate mounting
● Base mounting (enclosure mounting)
● 1-pole
● 2-pole
● Different functions (NC contact, NO contact and combinations thereof)
Color coding of the switching variants depends on the colors of the ID keys:
● 1NO → Green
● 1NC → Red
● 1NC1NC → yellow
The contact modules bear terminal designations in accordance with EN 50013.
Note
Stackability
With SIRIUS ACT, the modules are mounted on the holder without any further accessories.
The modules can be stacked without ne
eding to use a tool (max. 2 x 1-pole modules behind
one other).
Please note that a 2
-pole contact module may not be stacked on a 1-pole contact module.
