Product Overview
The Omron G7SA-5A1B DC24 is the 6-pole member of the Omron G7SA slim forcibly-guided safety relay family, with five normally-open contacts and one normally-closed contact (5PST-NO + SPST-NC) all rated 6 A at 250 VAC or 6 A at 30 VDC resistive. manufactured by Omron Corporation. Hengyixin Automation stocks this relay in Xiamen and ships within 3-5 business days; safety-rated components ship with a batch-trace certificate.
The 24 VDC coil draws 20.8 mA (500 mW, coil resistance 1,152 Ω) and is diode-protected for reverse polarity. The G7SA family is Omron's slim PCB-mount safety relay series, split into 4-pole (10-terminal) and 6-pole (14-terminal) variants.
The -ND variants include a coil-side green LED that lights when the coil is energised, useful for diagnostic on a populated safety panel.

Buying Checklist
- Pick G7SA-5A1B DC12 if your safety controller outputs 12 VDC instead of 24 VDC
- Pick G7SA-2A2B DC24 for 2 NO + 2 NC, G7SA-3A1B for 3 NO + 1 NC
- Pick G7SA-5A1B DC24 when you need 5 NO + 1 NC forcibly-guided safety relay with 24 VDC coil

FAQ for G7SA-5A1B DC24
What does forcibly-guided contact mean on the G7SA-5A1B?
Forcibly-guided contacts (per EN 61810-3) are mechanically linked so that if one contact welds closed due to overcurrent or end-of-life, the opposite contact cannot close on its own.
When should I pick G7SA-5A1B over G7SA-2A2B?
Pick G7SA-2A2B DC24 for the common case of dual-channel output with EDM (2 NO for two contactors + 2 NC for diagnostics/monitoring). Pick G7SA-5A1B DC24 when you need five independent NO outputs and one NC for EDM feedback — typical of a five-axis robot cell where each axis has its own safety contactor. If you need four NO + two NC, pick G7SA-4A2B. If you need three NO + three NC, pick G7SA-3A3B.
What socket should I use for the G7SA-5A1B?
Use one of the P7SA-14F socket family — the suffix indicates the variant. P7SA-14F is the basic screw-terminal socket. P7SA-14F-ND adds an operation-indicator LED plus a coil surge-absorbing diode. P7SA-14F-ND-PU DC24 uses Push-In Plus screwless terminals, which reduce wiring time by about 60 % compared with the screw-terminal version. P7SA-14P is a back-mounting PCB socket for OEM applications where the relay is soldered onto a custom board. All four accept the G7SA-5A1B DC24 relay module.
What is the coil current draw of the G7SA-5A1B DC24?
The 24 VDC coil draws 20.8 mA (about 500 mW) at the rated voltage. Coil resistance is 1,152 Ω. Must-operate voltage is 70 % of rated (16.8 VDC minimum to pick up) and must-release voltage is 15 % of rated (3.6 VDC maximum dropout). The coil is diode-protected against reverse polarity, so it can be driven directly from a 24 VDC PLC transistor output without an external flyback diode.
