Benefits
Relay outputs -- 3 safety contacts (N/O); instantaneous
Supply voltage for expansion modules
LED for -- Supply voltage at B1 and B2 / Input status; channel 1 / Input status; channel 2 / Switch status of the safety contacts / Fault
Plug-in connection terminals (either spring-loaded terminal or screw terminal)
The contact expansion module expands an existing circuit.
As the output relays are monitored via the base unit's feedback loop; the safety functions on the existing circuit are transferred to the contact expansion module.
The safety function remains effective in the case of a component failure.
Earth fault in the feedback loop -- Detected; depending on the base unit that is used.
Earth fault in the input circuit -- The output relays de-energize and the safety contacts open.
