Product Overview
The Omron G9SB-3012-A is an ultra-slim safety relay unit for emergency-stop and guard-door monitoring It is 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 unit is 22.5 mm wide on a DIN rail and combines 3 PST-NO safety contacts with 1 SPST-NC auxiliary feedback contact, all rated 5 A at 250 VAC. The supply is 24 VAC or 24 VDC and the input side accepts two inverse (mechanical switch) channels with auto-reset.
For a 45 mm wide safety relay with more contacts, pick the G9SA-301 AC-DC24. Key specs: Safety Output 3PST-NO (3 safety contacts, NO); Auxiliary Output SPST-NC (1 auxiliary feedback contact); Contact Rating 5 A at 250 VAC / 30 VDC, resistive; Supply Voltage 24 VAC (50/60 Hz) or 24 VDC; Power Consumption 1.7 VA / 1.7 W max; Input Channels / Reset 2 channels, inverse input, auto-reset; Time Operating 30 ms max; response 10 ms max; Standards EN ISO 13849-1 PLe / Cat.4, TUV, UL listed.
Key Features
- G9SB ultra-slim 22.5 mm safety relay unit, DIN-rail mount
- 3PST-NO safety contacts plus 1 SPST-NC auxiliary, all rated 5 A at 250 VAC
- 24 VAC / 24 VDC supply, 2-channel inverse input, auto-reset, 30 ms operate / 10 ms response
- EN ISO 13849-1 PLe / Safety Category 4 when wired per the datasheet; TUV approved
- SKU: G9SB-3012-A
- Series: Omron G9SB-series ultra-slim safety relay unit
- Voltage: 24 VAC
Best-Fit Applications
- Emergency-stop monitoring on a packaging line where the G9SB-3012-A sits between the E-stop pushbutton and the contactors driving the hazard
- Guard-door interlock on a CNC cell where two safety limit switches feed the inverse inputs and the SPST-NC contact feeds the PLC
- Spare drop-in for an existing safety relay panel where the previous G9SB-3012-A failed and the cabinet is wired for inverse auto-reset
Buying Checklist
- Pick the G9SB-3012-A for a slim 22.5 mm safety relay with 3 safety contacts and auto-reset.
- Pick the G9SB-3012-C instead when manual reset is required by the risk assessment.
- Pick the G9SA-301 AC-DC24 instead when a wider 45 mm safety relay with the same 3PST-NO output fits the cabinet better.

FAQ for G9SB-3012-A
What safety category does the G9SB-3012-A meet?
When wired per the datasheet examples (two-channel inverse input, auto-reset, monitored contactors), the G9SB-3012-A meets EN ISO 13849-1 Performance Level e and Safety Category 4. The exact category of the complete safety function is determined by the whole system, not just the relay.
What is the difference between the G9SB-3012-A and the G9SB-3012-C?
The G9SB-3012-A is auto-reset; the G9SB-3012-C is manual reset. Both share the same 3PST-NO + SPST-NC contact set and the same 22.5 mm housing.
Does the G9SB-3012-A work with safety light curtains?
Yes. The 2-channel inverse input accepts either mechanical limit switches, E-stop pushbuttons, or the OSSD outputs of a safety light curtain. Wire the curtain outputs to T11/T12 and T21/T22 as shown in the G9SB datasheet.
How is the G9SB-3012-A reset after an E-stop?
On auto-reset the safety contacts close again as soon as both inverse input channels are closed and the internal logic has cycled. For applications that require a deliberate manual reset, swap to the G9SB-3012-C.
