■Characteristics
Note: 1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
2. The bounce time is not included in the figure for operating time.
3. The response time is the time it takes for the main contact to open after the input is turned OFF.
4. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked.

Precautions
Wiring
Turn OFF the G9SB before wiring. Do not touch the terminals of
the G9SB while the power is turned ON, because the terminals
are charged and may cause an electric shock.
Use the following to wire the G9SB.
Stranded wire: 0.2 to 2.5 mm2
Solid wire: 0.2 to 2.5 mm2
Tighten each screw to a torque of 0.5 to 0.6 N·m, or the G9SB
may malfunction or generate heat.
External inputs connected to T11 and T12 or T21 and T22 of the
G9SB must be no-voltage contact inputs.
Applicable Safety Category
All G9SB Relays meet the requirements of Safety Category 4 of
the EN954-1 standards when they are used as shown in the
examples provided by OMRON. Relays may not meet the stan-
dards in some operating conditions. The G9SB-3010 can be
applied to Safety Category 3 of the EN954-1 using double break-
ing.
The applicable safety category is determined from the whole
safety control system. Make sure that the whole safety control
system meets EN954-1 requirements.
Mounting Multiple Units
When mounting multiple Units close to each other, the rated cur-
rent will be 3 A. Do not apply a current higher than 3 A.
Connecting Inputs
If using multiple G9SB models, inputs cannot be made using the
same switch. This is also true for other input terminals.
Earth Short
A positive thermistor is built into the G9SB circuits, so you can
detect earth short breakdowns and breakdown shorts between
channel 1 and channel 2. (Detection of breakdown shorts
between channel 1 and channel 2 is supported for G9SB-2002-
@ /
3012-
@ models only.)
Note Inorder to detect earth short breakdowns, connect the mi-
nus side of the power supply to ground.
