■ 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 mm
2
Solid wire: 0.2 to 2.5 mm
2
Tighten each screw to a torqu e of 0.5 to 0.6 N·m, or the G9SB
may malfunction or generate heat.
Extern al inputs c o nnected to T11 an d T12 or T21 and T22 of the
G9SB must be no-voltage contact inp uts.
Applicable Safety Category
All G9SB Relays me et the requi rements of Safety Catego ry 4 of
the EN954-1 standards when they are used as shown in the
examples provided by OMRON. R elays may not meet the standards in some operating conditions. The G9SB-3010 can be
applie d to Safety Cate go ry 3 of th e E N954-1 us ing double breaking.
The applicable safety category is determined from the whole
safety control system. Make sure that the whole safety control
syste m me et s E N954-1 requ irements.
Mounting Multiple Units
When mounting multiple Units close to each other, the rated current will be 3 A. Do not apply a current higher than 3 A.
Conne cting Inputs
If using multiple G9SB models, inputs cannot be made using the
same switch. This is also true for other input terminals.
Earth Sh ort
A positi ve thermis tor is built int o the G9SB circuits, so you can
detect e arth shor t breakdowns and breakdown shorts be tween
channel 1 and channel 2. (Detection of breakdown shorts
between channel 1 and channel 2 is supported for G9SB-2002-
@
/
3012-
@
models only.)
Note In order t o det e ct ear t h s hort b rea kdo wns , conne ct t he mi -
nus side of the power supply to ground.
