Safety relay for PCB mounting
The Omron G7SA2A2B24DC is a monostable PCB safety relay with a 2NO + 2NC contact configuration, switching 6 A at 250 V AC or 125 V DC. The 24 V coil draws through 1.6 kOhm, and the relay handles 1.5 kVA switching power. The 2NO + 2NC arrangement means it can break both channels in a safety circuit while keeping the NC feedback loop closed — standard for Category 3 / PL d or SIL 2 applications where the NC contacts monitor the actuator state.
Mounting and footprint
PCB-mount with radial leads. The 40 mm width and 27.5 mm height fit a standard 2-pole safety relay footprint; the 13 mm depth keeps it low-profile on crowded boards. Radial leads suit wave-solder assembly — verify the lead pitch against your PCB layout before committing the BOM.
