The Omron G2R-1-E is one of the most widely specified general-purpose power relays in industrial control panels, and for good reason — it’s a proven, reliable part with wide availability. This assembled module puts four genuine G2R-1-E relays on a pluggable DIN-rail carrier, which turns a from-scratch panel wiring job into a drop-in swap.
What It Is
This is a 4-channel relay module built around genuine Omron G2R-1-E relays rated 16A at 250VAC (or 30VDC), supporting both AC and DC control signals. Each channel has its own status LED and coil-protection freewheeling diode, mounted on a Taiwan-made DIN rail carrier that fits 35mm, 32mm, or 15mm rail (or can be disassembled for panel mount).
Key Features
- 4 channels of genuine Omron G2R-1-E relays, 16A @ 250VAC / 30VDC per channel
- Supports AC or DC control signals
- Per-channel LED status indicators
- Freewheeling diode coil protection built into each channel
- High-quality screw terminal blocks on dual-copper-layer FR-4 PCB
- Pluggable relays — swap a failed relay without rewiring the panel
Pros and Cons
The pluggable design is the real time-saver — when a relay eventually fails after enough switching cycles, you unclip it and plug in a replacement instead of desoldering or rewiring terminals. Using genuine Omron relays rather than an unbranded equivalent also matters if your panel documentation specifies OEM parts.
At $46.50 for 4 channels, it costs more than buying bare relays and building your own terminal block, but the assembly time saved and the pluggable maintenance access generally justify it for panel builds.
Who It’s For
Panel builders who want genuine Omron relay reliability with the convenience of a pre-wired, pluggable DIN-rail module instead of assembling terminals and relays separately.
Verdict
For control panels that call for Omron G2R-1-E relays, this pre-assembled pluggable module saves real build time without substituting a lesser part.
