Application and Function
Relay Outputs relay output has its own LED to indicate the status of the output.
Each output of the module is fitted with two safety relays in diversity with positively guided contacts and one standard type relay. Internal fuses are used to limit the switching current of the output contacts to 60% (3.15 A) of the maximum admissible value (according to VDE 0116, En 298). The contact outputs can be used for safety shutdowns. For DC switching the contact circuit must be additionally equipped with an external fuse adapted to the maximum admissible current.
An output is in a safe state when it is
If the module has a fault all outputs are switched off. In the event of a fault at Ethernet communication the concerning output is set to the initial value. How the actuators respond in such a case should be taken into account.
Faults in one or more channels as well as a fault on the module are indicated by the FAULT LED on the front plate of the remote output module.
The relay outputs are connected to the following terminals:
