DA262-16: Mains-powered Dual Quad relay with integrated UPS back-up

A mains-powered universal relay unit with VRLA battery back-up support and two Octo-Relay modules with eight independent DPCO relays each. Each relay PCB module operates at 12V DC and can switch up to 30V DC 1A. The power supply unit provides 12V (13.7V) DC 1.5A to power the relay PCB cards. Each relay card also has an inhibit line that can de-energise all 8 relays per pcb when pulled high.

A VRLA battery of up to 7Ah can be fitted in the enclosure and charged by the power supply to enable battery back-up.

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).
