Solid State Relays with Failure Detection Function
G3PC
CSM_G3PC_DS_E_1_2
Refer to Safety Precautions for All Solid State Relays.
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.

SSR half-wave short-circuit OFF
SSR open-circuit
Alarm display (between
terminals X1 and X2)
(See note 3.)
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. 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. When grounding to a neutral point with a three-phase start connection, an overvoltage will be applied to the G3PC if the neutral point
becomes disconnected, possibly causing product failure. Make sure the connection to the neutral point is secure.
3. Detection is not possible for the heater indicated with an asterisks with a three-phase delta connection.

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.
