Relay module for digital output signals for switching loads with max. 3 A nominal current and a maximum voltage of 24 V DC. The switch contact is protected by an integrated replaceable 3 A fuse. If the fuse fails, this is indicated by an LED. A plug-in bridge determines whether an N/O contact or an N/C contact is used. The module is installed on a corresponding VIP I/O-Marshalling base element by means of plug-in contact. Installation in zone 2, “ec” type of protection is permitted.
