Operating input (between terminals A1 and A2) Detection time Alarm display (See note 3.) SSR short-circuit OFF 0.5 s max. (See note 2.) Red Open collector transistor output 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.

SSR with Failure Detection Function G3PC J-75 SSR Heater 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. Precautions Refer to the Technical Information for SSRs (Cat. No. J137) for general precautions. Wiring • When using crimp terminals, observe the terminal clearances shown below. ■ Correct Use Main Circuit Power Supply Operating Input/Alarm Output (Terminals 1 to 3) (Terminals A1, A2, X1, and X2) Before Actual Operation 10 1. In actual operation, the G3PC may cause accidents that were unforeseeable at the theoretical stage. Therefore it is necessary to test the G3PC under a variety of conditions that are possible. As for the characteristics of the G3PC, it is necessary to consider the differences between G3PC Units. 2. The ratings in this datasheet are for testing in a temperature range of 15 to 30°C, a relative humidity range of 25% to 85%, and an atmospheric pressure range of 88 to 106 kPa. When testing operation, it is necessary to confirm correct operation not only with the actual load that will be used, but also at the same ambient conditions as for actual operation. Mounting Method 7.0 12.4 10 M3.5 • Be 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 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 Terminal number Screw terminal diameter Tightening torque A1, A2, X1, X2 M3.5 0.59 to 1.18 N·m 1/L1, 2/T1, 3 M4 0.98 to 1.47 N·m Horizontal Mounting Vertical direction Vertical Mounting Be sure to tighten the screws to the specified torques given below. Not doing so may result in malfunction. Panel Panel Note: Use the G3PC at a load current of 50% of the rated load current when it is mounted horizontally. Side-by-side Mounting Wiring duct 5 mm 80 mm min. Wiring duct 80 mm min. Note: Use the G3PC at a load current of 80% of the rated load current when it is mounted side-by-side.
