Omron G3PJ Series Solid State Relay, 25 A Load, DIN Rail Mount, 528 V ac Load, 24V Control

Omron G3PJ Series Solid State Relay, 25A Maximum Load Current, 528V AC Maximum Load Voltage - G3PJ-525B DC12-24

This solid-state relay is a DIN-rail mounted switching device designed to control AC loads using a low-voltage DC control signal. It employs a triac output with zero-cross switching to manage AC circuits up to high system voltages while operating across a wide ambient temperature range for industrial automation environments.

Features and Benefits:

• Supports 25A load for handling substantial AC currents
  Operates up to 528 VAC for high-voltage AC systems
  Accepts 12–24V control facilitating common PLC outputs
  Zero-cross switching reduces inrush and EMI during switching
  Low off-state leakage of 20 mA minimises standby current draw
  Rated for continuous use up to 80 °C ambient for harsh conditions

Applications

• Suitable for HVAC fan and heater control in commercial systems
  Ideal for motor control in conveyor and packing equipment
  Used for switching resistive and lightly inductive AC loads
  Can be used for panel-mounted process automation installations

What Terminal arrangement does it use for wiring?

It provides screw-type terminals that permit secure, field-friendly connections to both control and load conductors.

How is it mounted within electrical enclosures?

The unit is designed for DIN-rail installation enabling Rapid fitting and standardised panel layout.

What switching behaviour should be expected at turn-on?

The relay employs zero-cross switching so it closes near the AC waveform zero crossing, reducing transient currents at switch-on.

What environmental temperature range can it tolerate during operation?

It functions reliably from −30 °C up to 80 °C ambient, covering a wide span of industrial conditions.

Notes

Temperature can affect current rating; please consult the data sheet for potential derating.
