The Omron G6B-4BND-DC24 is a DIN-rail-mounted general-purpose relay with four normally-open SPST contacts (4PST), a 24V DC coil, and a rated contact current of 5 A at 250V AC or 5 A at 30V DC. The LED indicator gives a quick visual on coil state during panel troubleshooting — no push-to-test button on this variant, so the LED is your go-to for confirming the coil is pulled in. Snaps onto standard DIN rail, occupying a 16-pin footprint. The 4PST arrangement means four independent switch legs, all normally open — useful for switching multiple signal or low-power load circuits from one coil without shared commons.
Rated 5 A at 250V AC and 5 A at 30V DC. That AC rating covers resistive loads like pilot lights, contactor coils (with proper suppression), and small solenoid valves in control panels. The DC rating at 30V is typical for PLC digital outputs or DC bus switching — but watch the DC load type; inductive DC loads (brakes, clutches) need a free-wheel diode across the load, or the arc at break can weld the contacts short of the rated life. Dielectric strength checks out at 2,000V AC between coil and contacts, and 1,000V AC between contacts of the same polarity — that's standard for a 250V-rated relay and keeps you clear of flashover in a 24V DC control circuit sharing a panel with line-voltage gear.
