The Omron G6C-1117C-US-DC12 is a 1 Form A (SPST-NO) power relay with a 12 VDC coil, part of the G6C series. It is a current-production part.
What the 1 Form A and 12 VDC coil mean for fit
1 Form A means a single normally-open contact — one circuit, make-only. That's a straightforward load-switching relay: energize the coil, the contact closes. The 12 VDC coil is standard for many PLC output cards and control transformers; it pulls in reliably at nominal voltage and drops out cleanly below the release threshold. No polarity concerns on DC coils, but verify your flyback diode placement if the driver circuit doesn't include one.
