Refer to Warranty and Application Considerations (page 1), Safety
Precautions (page 4), and Technical and Safety Information (page 6).
Detects failures in SSR used for heater
temperature control and simultaneously
outputs alarm signal. This SSR supports the
safe design of heater control systems, and
contributes to maintenance improvements
by the user.
• Main detection items:
SSR short-circuits and SSR open-circuits
• Alarm output possible to NPN/PNP-input devices.
• The failure-detection function is built-in and power is supplied
from the main circuit power supply making wiring simple.
• Slim design (width: 22.5 mm) incorporating a heat sink.
• In addition to screw mounting, DIN track mounting is also
possible.
• Certified by EC, UL, and CSA.

ON
SSR half-wave open-circuit ON
Note: 1. The contents of each of the above failure modes is as follows:
SSR short-circuit: SSR output circuit remains in the ON state.
SSR half-wave short-circuit: SSR output circuit remains in the ON state in one direction.
SSR open-circuit: SSR output circuit remains in the OFF state.
SSR half-wave open-circuit: SSR output circuit remains in the OFF state in one direction.
In addition to the failure modes listed above, detection of circuit disconnections for the load circuit is also possible. (As a rough guide,
circuit disconnection will be detected if the load impedance is greater than or equal to 1 MΩ.)
2. The same power supply is used for both the detection and for the output circuit and so detection is not performed during power
interruptions.
3. If power supply (terminal 3) is in the open state, the SSR will still turn ON and OFF in the same way but the failure detection function and
alarm display will not operate properly.

Note: 1. If the detection power supply terminal (terminal 3) is not connected, failure detection is not performed and so be sure to connect this
terminal.
2. If the load is connected to terminal 1/L1, failure detection may not operate correctly and so connect the load to terminal 2/T1.
3. With inductive loads (relay coil, etc.), connect back-current prevention diodes to both sides of the load.

Safety Precautions
■ Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
Wiring
• When using crimp terminals, observe the terminal clearances
shown below.

DIN Track Mounting
When mounting to a DIN track, mount the G3PC until it clicks into
place, otherwise it become loose during use and fall. Fix both ends
with end plates.

Panel Mounting
When mounting directly to a panel, observe the following conditions:
Screw diameter: M4
Tightening torque: 0.98 to 1.47 N·m

• Make sure that all lead wires are of a thickness appropriate for the
current.
• The output terminals are charged, and touching them may result in
electric shock, even when the G3PC is OFF. Separate the outputs
from the power supply by installing a circuit-breaker at a higher
level in the circuit.
Be sure to tighten the screws to the specified torques given below.
Not doing so may result in malfunction.
