Agility AE-04-005D-1-B-C 4 Channel Relay Card
Agility AE-04-005D-1-B-C 4 Channel Relay Card is a multi-channel relay interface designed for switching control signals and electrical loads in industrial automation systems. The module provides four independent relay channels operating with a 5 VDC coil voltage, allowing connection between compatible control electronics and field devices. Each channel uses a one changeover contact configuration, while Omron G5Q Series relays provide the switching function. Freewheeling diode coil protection helps suppress voltage spikes generated during relay switching. The four-channel configuration is suitable for PLC interfaces, machine control panels, and automation equipment requiring multiple relay outputs.
