Extending the number of contacts
Often, more contacts are required than those
that are normally available. The positively driven
contact extension modules can be used in such
applications. Depending on the requirement,
they can be connected as modules.
Positively driven coupling relays
Like all PSR switching devices, the coupling relays
for universal use also have positively driven
contacts in accordance with the EN 50205
standard. They can be used in all safety-related
applications due to the fully positively driven
N/C and N/O contacts.
