B&R X90RO440.04-S1

9 to 32 VDC 4 safe relay outputs Output type "Relay" Nominal output current 2x 2 A and 2x 4 A Normally open contact Single-channel isolated outputs X2X Link The relay option board provides 4 additional safe relay outputs. Communication to the mainboard is made possible via X2X Link. The modules can be used for controlling floating actuators in safety-related applications up to PL e or SIL 3. Safety relays are installed within the module. The positively driven feedback contacts are evaluated within the module. The safe digital output modules have a start interlock on error in the event of network errors.
