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.

■ 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.
