DA258: Dual Octo-relay

  • Two Octo-relay PCB modules
  • Sixteen 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

DA258: Dual Octo-relay

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

Typical uses include changing the polarity of signals, 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) need to be over-ridden by another system (e.g. a fire panel).
