Lifesafety Power RB8-BOXED 8A Auxiliary Relay DPDT

Overview

The RB8-BOXED is an 8-ampere auxiliary relay module with dual-pole, dual-throw (DPDT) switching architecture and automatic voltage detection. Deploy this in access control, door strike, and lock circuits where you need isolated relay control fed by power supplies or control panels. Auto voltage sensing eliminates manual jumper configuration — the relay adapts to 12VDC or 24VDC input without rewiring, reducing installation time and field errors on mixed-voltage deployments.

Compatibility

The RB8-BOXED integrates with access control systems and power management platforms that output 12VDC or 24VDC logic signals. Typical applications include triggering solenoid door strikes, electric locks, and auxiliary equipment loads up to 8 amps per relay contact. Verify your control panel's relay output voltage (12VDC or 24VDC) matches the input terminals — auto voltage detection handles both without configuration.

Installation Notes

Wire the RB8-BOXED (model RB8) between your control panel relay output and the load device. The DPDT configuration provides two independent normally-open/normally-closed contact sets, enabling simultaneous control of two separate 8A circuits or redundant switching of a single load. Ensure the combined load current does not exceed 8 amperes per relay contact to prevent nuisance dropout or contact degradation. Mount in a dry enclosure or DIN rail assembly alongside your power conditioning equipment.
