The Relay Card 8 Channel can be powered from a bottom level input and can be successfully deployed, when a relay output is demanded from an enclosed accumulator unit. This channel is alternatively provided with some strong and handy boards that offer an easy technique to interface a bottom level control output through a control framework like ports to greater level loads, for example, a lesser voltage screen regulator. In addition, the offered Relay Card 8 Channel can be employed to reciprocate control output logic, when demanded. The unit deploys a captive screw ends for easy and quick wiring and has on-built LEDs, which effectively monitor the state of relay.
