SSR
Solid State Relays with Failure Detection Function
G3PC
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.

Operation
■Failure Detection Function
Conditions for SSR Failure Detection
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.
Connection Diagrams (Main Circuit)
The following diagrams show the applicable load connection configurations for SSR failure detection.
Note: 1. With 3-phase connection, so that the power supply voltage is applied between the G3PC’s terminals 1/L1 and 3, connect the desired
phase to terminal 3.
2. Above mentioned products are 200V only. They are not suitable for three-phase 400V, but for three-phase 220V only.
Timing Chart
Note: After failure detection, if the detection conditions differ to the conditions given under Conditions for SSR Failure Detection, alarm output is
reset.

Appearance
■Connection Example
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.
Mounting Method
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
Vertical Mounting Horizontal Mounting
Note: Use the G3PC at a load current of 50% of the rated load current
when it is mounted horizontally.
Close Mounting
Note: Use the G3PC at a load current of 80% of the rated load current
when it is mounted side by side.
Wiring
•When using crimp terminals, observe the terminal clearances
shown below.
•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.
Tightening Torque
Be sure to tighten the screws to the specified torques given below.
Not doing so may result in malfunction.
