G3PC-220B-VD DC12-24

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.

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.

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.

Mounting Method • 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 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. Be sure to tighten the screws to the specified torques given below. Not doing so may result in malfunction. Terminal number Screw terminal diameter Tightening torque Panel Mounting A1, A2, X1, X2 M3.5 0.59 to 1.18 N·m When mounting directly to a panel, observe the following conditions: Screw diameter: M4 Tightening torque: 0.98 to 1.47 N·m 1/L1, 2/T1, 3 M4 0.98 to 1.47 N·m Horizontal Mounting Vertical direction Vertical Mounting Panel Panel Note: Use the G3PC at a load current of 50% of the rated load current when it is mounted horizontally. Close Mounting Wiring duct 5 mm 80 mm min. Wiring duct 80 mm min. SSR Note: Use the G3PC at a load current of 80% of the rated load current when it is mounted side by side.
