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. 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. The SeaI/O-580PoE has all the features of our 580E module and is a Class 0 (IEEE 802.3af-2003) Power over Ethernet device. Power and data are transferred over a single CAT5 cable, which completely eliminates the need for externally powering the module or I/O.
The SeaI/O-580E and SeaI/O-580PoE are $499 each in low quantities and available from stock.
