TCP184 industrial 4 x 16A relays bit-kit Idle speed at 12 V:The tcp184 is an Ethernet connected relay module featuring 4 channels of 16Amp 250Vac relays. Each relay has both normally open (NO) and normally closed (NC) as well as the common available on three terminals. It has snubbers fitted between the Common and N O contacts. In addition to the relays, the tcp184 has 8 input channels which may be individually configured to be: Active low input with pull up (allows direct connection of volt free contacts).
