Ethernet Modbus TCP to 32 Isolated Dry-Contact Inputs

Control and monitor 32 isolated, dry contact inputs via any 10/100BaseT Ethernet connection with the SeaI/O-580E. The inputs detect a contact closure between two externally wired field contact points. The dry contact (no-voltage) inputs are ideal for monitoring applications such as alarm contacts, HVAC controls, demux boards, sensing relay contacts, and other control system inputs.

I/O connections are made using convenient 3.5mm field removable screw terminal connectors. Field wiring is simplified since no external power is required to trigger the inputs. The SeaI/O-580E is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
