Wiring 8-Pin Relays

The pinout of an 8-pin relay like the TR-200 includes coil terminals, common contacts, and normally open/closed switching contacts arranged for a rear-mounted eight-pin polarized connector. This design mates with a Cinch-Jones 2408SB socket, ensuring correct orientation and secure, reliable connections during installation.

Most 8-pin traffic signal relays operate on standard AC coil voltages, with the TR-200 rated to function reliably down to 89 VAC under brownout conditions. Its transient-suppressed, full-wave rectified coil design allows chatter-free operation even when supply voltage fluctuates below nominal levels.

The TR-200 Flash Transfer Relay is designed to mate with a Cinch-Jones 2408SB socket. This rear-mounted eight-pin polarized connector ensures a secure, correctly oriented fit that simplifies installation and reduces the risk of wiring errors in traffic signal cabinets.

A transient-suppressed, full-wave rectified coil converts AC input to a smoother DC signal, reducing contact chatter and mechanical wear. This design also lowers power consumption compared to conventional AC coils, extending relay lifespan and improving reliability in continuous-duty traffic signal applications.

Yes, relays like the TR-200 are specifically engineered for brownout resilience, maintaining chatter-free operation at voltages as low as 89 VAC. This makes them well-suited for traffic signal infrastructure where grid voltage can fluctuate due to demand surges or utility instability.

Traffic signal relays are typically designed to align with NEMA TS2 and applicable state DOT procurement specifications governing traffic control equipment. Manufacturers often provide downloadable data sheets and procurement specifications to help agencies verify compliance before installation in signal cabinets.
