Allen-Bradley 8-670 DPDT Relay

The Allen-Bradley 8-670 DPDT relay is designed to switch two independent circuits in industrial control systems, offering two Form-C contacts that are actuated by a single coil to deliver coordinated dual-load control and to provide electrical isolation between the control logic and the power circuits. It is driven by a 24 VDC coil, energizing the two DPDT contacts (double-pole, double-throw) to connect or disconnect load circuits according to the control logic. The contact rating specifies 5 A at 120 VAC or 240 VAC, allowing this relay to handle common automation loads while keeping control and power circuits electrically isolated. In automation applications, the 8-670 provides a compact, two-pole, two-throw switching solution for signaling, interlock, and sequencing tasks across AC-powered circuits, all under the well-known Allen-Bradley reliability standard. Designed to integrate with standard control circuitry, the 8-670 provides clearly defined coil and contact terminals, enabling predictable wiring diagrams and straightforward troubleshooting in automation setups.
