These provide additional safety contacts that mirror the switching state of the base unit without any delay. They are used when immediate action is required in response to a safety condition. These modules offer additional contacts with a time delay function. They allow for a time lag before the contacts change state, which can be crucial for safely managing processes or equipment shutdowns.
The base units in the PNOZ X range act as the core safety relay or control system. They include integrated monitoring functions such as feedback loop monitoring to ensure the correct operation of safety circuits. These are connected to the base unit to increase the number of available safety contacts. They can be installed on the same DIN rail as the base unit and communicate directly with it to ensure synchronized operation.
