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.

G-130 Safety Sensors / Components
Precautions
Wiring
Turn OFF the G9SB before wiring. Do not touch the terminals
of the G9SB while the power is turned ON, because the termi-
nals 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.
Ap
plicable Safety Category
G9SB-200 # - # /301 # - # meet the requirements of Safety Cate-
gory 4 of the EN954-1 standards when they are used as
shown in the examples provided by OMRON. Relays may not
meet the standards in some operating conditions. The G9SB-
3010 can be applied to Safety Category 3 of the EN954-1 us-
ing double breaking. The applicable safety category is deter-
mined 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
current 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 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 to detect earth short breakdowns, connect the minus side of the
power supply to ground.
