Safety Relay Unit
Refer to the “Precautions for All Relays” on page I-9 and “Precautions for All Relays with Forcibly Guided Contacts” on page G-2.
I
The G9SA can be installed in any direction.
Use the following to wire the G9SA.
Stranded wire: 0.75 to 1.5 mm
Solid wire:
Tighten each screw to a torque of 0.78 to 1.18 N·m, or the G9SA
may malfunction or generate heat.
External inputs connected to T11 and T12 or T21 and T22 of the
G9SA-301 must be no-voltage contact inputs.
PE is a ground terminal.
When a machine is grounded at the positive, the PE terminal should
not be grounded.
Do not remove the connector cover of the G9SA-301, G9SA-501,
G9SA-321-T@, or G9SA-TH301 unless an Expansion Unit is being
used.
Turn OFF the G9SA before connecting the Expansion Unit.
When an Expansion Unit is being used, remove the connector cover
from the G9SA Safety Relay Unit (G9SA-301, G9SA-501, G9SA-
321@, or G9SA-TH301) and insert the connector of the Expansion
Unit’s connector cable.
When mounting multiple Units close to each other, the rated current
will be 3 A. Do not apply a current higher than 3 A.
If using multiple G9SA models, inputs cannot be made using the
same switch. This is also true for other input terminals.
Turn OFF the G9SA before wiring the G9SA. Do not touch
the terminals of the G9SA while the power is turned ON,
because the terminals are charged and may cause an
electric shock.

A positive thermistor is built into the G9SA circuits, so you can detect
earth short breakdowns and breakdown shorts between channel 1
and channel 2. If the short breakdown is canceled, reset is
automatic.
I
G9SA-series 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. The Relays may not meet the
standards in some operating conditions. The OFF-delay output of
models G9SA-321-T@ and EX031-T@, however, conform to Safety
Category 3.
The applicable safety category is determined from the whole safety
control system. Make sure that the whole safety control system
meets EN954-1 requirements.
