Omron G2RV Interface Relays 2026: SEA Panel Guide

A panel builder in Bangkok or Ho Chi Minh City who asks their automation distributor for Omron MY2N relays in August 2026 will increasingly be handed the G2RV-ST701 DC24 or G2RV-ST700 DC24 instead. That is not a sales pitch. It is a product transition that is already underway, and panel shops that understand it now will make better purchasing decisions than those still working from five-year-old bills of materials.

This article covers what panel builders in Southeast Asia actually need to know: what the G2RV-ST701 DC24 and G3RV-SR700-D DC24 can do, what the MY2N migration path looks like in practice, where the products are in stock through authorized channels, and what the pricing and lead time situation looks like right now.

What the G2RV-ST701 DC24 Actually Does

The G2RV-ST701 DC24 is a slim plug-in interface relay from Omron with these verified specifications from the catalog:

Part number G2RV-ST701 DC24, SPDT contact arrangement, 6 A at 250 V AC resistive load, 24 V DC coil
LED and mechanical flag indicator for coil status at a glance
Operating temperature –40 °C to +55 °C, suitable for unaired factory floor conditions
UL recognized (File No. E41515), IP20 rated
DIN rail mounting on 35 mm rail
Lifecycle stage: Current — active production, not announced for end-of-life

The 6 mm wide housing is narrower than a standard electromechanical relay. Eight G2RV relays take roughly 216 mm of DIN rail. The equivalent eight MY2N relays take about 288 mm. That 72 mm difference affects the mechanical layout when you are designing a 24-relay I/O card cage into a 400 mm wide enclosure.

The plug-in contact card design means you pull a faulty relay and push a replacement in without undoing any wiring. For panel shops doing field service on OEM machines, that is a genuine maintenance advantage over the MY2N barrel format.

The G2RV-ST700 DC24 is the standard variant, with 12 V DC and 24 V DC coil options. Both ST700 and ST701 are listed as currently active in Omron's catalog.

The G3RV-SR700-D DC24 Solid State Relay

For applications that benefit from solid state switching, the G3RV-SR700-D DC24 is mechanically compatible with G2RV sockets:

Part number G3RV-SR700-D DC24, solid state, zero-cross function absent, for DC load switching
Maximum load current 2 A – 3 A, maximum rated load voltage 24 V DC – 48 V DC, maximum applicable load voltage up to 60 V DC
Input voltage range 4 V DC – 30 V DC, maximum operating input 26.4 V DC – 32 V DC
Inrush current tolerance 30 A at 60 Hz for one cycle
Lifecycle stage: Mature

This relay suits DC motor drive enable signals, solenoid valve coils, and other DC load switching where silent operation and long contact life are priorities. It is not a direct replacement for the electromechanical G2RV in all applications — the 2 A – 3 A current limit is considerably lower than the 6 A electromechanical rating. For higher current DC loads, use the appropriate Omron G3 series SSR.

Why the MY2N to G2RV Transition Is Happening Now

The Omron MY2N has been a standard component in control panels across Southeast Asia for decades. It is not formally end-of-life, but several things are converging to push the market toward G2RV.

Thailand's automation investment is accelerating. Delta Electronics (Thailand) hosted the Future Industry Summit 2026 in Bangkok in August, convening government and industry leaders to advance AI and electrification in Thai manufacturing. The event reflected a broader pattern: industrial automation investment in Thailand and Vietnam is growing as manufacturers reshore production and upgrade factory infrastructure.

More significantly, Omron sold its Device & Module Solutions Business to Carlyle Group in March 2026 for approximately ¥81 billion. Carlyle's ownership creates a new commercial entity managing product lifecycle decisions, including which Omron relay SKUs remain in production and which get rationalized. This makes the MY2N to G2RV transition more concrete and time-bound than a speculative trend. Lead times on legacy MY2N formats are tightening as authorized distributors reduce stocking of older SKUs.

Authorized distributor stock is improving. Mouser Electronics confirmed in August 2026 that it is actively stocking Omron Industrial Automation relay and I/O products, including G2RV variants, through its Singapore warehouse with same-day or next-day dispatch to Southeast Asian destinations. This is relevant because Mouser is an authorized distributor — buying from authorized channels ensures full warranty and product authenticity.

Sourcing Options in Southeast Asia, August 2026

Mouser Electronics carries G2RV-ST700 DC24 and G2RV-ST701 DC24 through its Singapore operation, with same-day or next-day dispatch for urgent orders. RS Components and Digi-Key also hold Omron relay inventory through their Southeast Asian distribution networks — these are authorized distributors and their stock is available as of August 2026.

Lead times from authorized franchised distributors for standard G2RV variants run four to eight weeks for quantities up to 100 units. Non-standard coil voltages and contact configurations may need eight to sixteen weeks. Panel shops with scheduled production runs should convert from reactive purchasing to a quarterly forecast with their distributor to lock in allocation and secure volume pricing.

On pricing in August 2026, the G2RV-ST701 DC24 typically falls in the USD 12 – 22 per unit range for small quantity orders from franchised distributors, with price breaks at 50 units or more. The G3RV-SR700-D DC24 runs at a modest premium over equivalent electromechanical G2RV variants. For current pricing, check Mouser's published list price or request a quote from RS Components — prices shift with exchange rates and distributor stocking cycles.

Minimum order quantity (MOQ) is one unit across major franchised distribution channels.

To verify authenticity: check the Omron lot number format, confirm the UL file number on the relay housing (UL File No. E41515 for G2RV-ST series), and purchase only from authorized Omron distributors — authorized distributors are verifiable through Omron's distributor lookup tool.

Weidmuller IM03 and Phoenix Contact PLC-RSC as Alternatives

The Weidmuller IM03 is worth considering for panel shops building equipment destined for European OEM markets, particularly where ATEX or IECEx hazardous area certifications are required — a niche the Omron G2RV does not specifically target. The IM03 uses a similar plug-in card concept and is mechanically compatible with Weidmuller's relay sockets.

Phoenix Contact's PLC-RSC relay system is positioned within the PLCnext ecosystem, offering integrated diagnostics and programming across the automation system. Panel shops already committed to Phoenix Contact for I/O modules and power supplies may find the PLC-RSC simplifies their supplier management.

For most Southeast Asian factory automation applications, the G2RV-ST701 DC24 from Omron through an authorized distributor offers the best combination of availability, price, and maintenance convenience.

Practical Steps for Panel Shops in 2026

For new panel designs, adopt the G2RV-ST701 DC24 or G2RV-ST700 DC24 as the standard slim interface relay. Factor the 6 mm housing width into the DIN rail layout from the start of mechanical design.

For existing MY2N-based panels, identify which relay sockets are in use and check whether G2RV plug-in replacement cards are socket-compatible. Keep a small stock of replacement cards for the most failure-prone positions.

For solid state switching requirements, specify the G3RV-SR700-D DC24 for DC loads up to 3 A and 48 V DC. For higher current DC loads or AC loads, use the appropriate Omron G3 series SSR.

The relay market is shifting. Panel shops that update their standard specifications now will find the transition much smoother than those waiting for the next emergency MY2N reorder.
