DA256: Octo-relay

  • Eight 12V DC-powered DPCO Relays
  • High and low transistor-driven inputs
  • Tamper-switched mild steel enclosure
  • Contact rating 30V DC 1A
  • De-power all relays with inhibit function

DA256: Octo-relay

A universal relay unit with eight independent DPCO relays on one PCB. 12V DC operation. The unit also has an inhibit line that de-energises all 8 relays when pulled high.

Typical uses include changing the polarity of signals and switching higher currents and voltages. It can also be used as an interface between different systems, e.g. intruder alarm to access control or fire alarm to access control. This unit can also be useful when the control of a number of components (e.g. door locks) needs to be over-ridden by another system (e.g. a fire panel).
