Omron G2RV-ST500 48VAC/DC Slimline Relay Technical Guide

The Omron G2RV-ST500 48VAC/DC slimline relay is designed for compact industrial control panels where space, wiring speed, and reliable signal switching matter. It belongs to the Omron G2RV-ST Slim I/O Relay family, known for a 6.2 mm body width, DIN rail mounting, Push-In Plus terminals, and an integrated low-profile socket.

This model uses a 48 VAC/DC rated input voltage. According to Omron technical data, the 48 VAC/DC coil rating has approximately 5.9 mA at 50 Hz, 6.4 mA at 60 Hz, and 5.4 mA DC rated current, with approximate power consumption of 0.3 VA on AC and 250 mW on DC. The relay operates at 80% max. of rated voltage and releases at 10% min. :contentReference[oaicite:0]{index=0}

Technical Characteristics

The standard G2RV-ST500 version is suitable for higher load switching than the AP microload versions. Omron lists the standard type with SPDT contact configuration, 6 A rated carry current, 6 A at 250 VAC, and 6 A at 30 VDC for resistive loads. It also supports Push-In Plus terminal wiring and DIN rail installation, making it practical for dense machine control cabinets.

Where It Is Commonly Used

This relay is often selected for PLC interface circuits, automation panels, machine safety auxiliary circuits, HVAC controls, signal isolation, and compact relay banks. Its transparent case and mechanical indicator help technicians inspect relay status without removing the device. Omron also highlights reduced wiring time, improved LED visibility, and a compact body for high-density mounting.

Omron G2RV-ST500 48VAC/DC FAQ

What is the Omron G2RV-ST500 48VAC/DC slimline relay used for?

It is used as an interface relay in industrial automation panels, especially when 48 VAC or 48 VDC control voltage is present.

Is it suitable for compact control cabinets?

Yes. Its slim 6.2 mm profile helps reduce panel width and supports high-density relay mounting.

What contact form does it use?

It uses an SPDT contact form, also known as 1 Form C, allowing one common contact to switch between normally open and normally closed outputs.

Does it have Push-In Plus terminals?

Yes. Push-In Plus terminal technology supports faster wiring and easier installation compared with traditional screw wiring.

Is this the same as the AP microload version?

No. The G2RV-ST500 is the standard version with higher load capacity. The G2RV-ST500-AP versions are designed for microload switching.
