Product Overview
The G6B-4BND DC24V is a 4-channel terminal relay that packs four independent G6B mini-relays into one DIN-rail-mountable block, with 4PST-NO (4PDT) contacts rated 5 A at 250 VAC or 5 A at 30 VDC per channel. Each channel has its own LED operation indicator, separate input and output screw terminals, and a plug-in G6B relay module that can be replaced in seconds without disturbing the wiring. The block mounts on a standard 35 mm DIN rail or screws to a panel, and the four isolated channels let you switch four independent loads from four independent control signals without cross-talk.
How G6B-4BND differs from siblings
The G6B-4 family splits along three axes: contact form (4BND = 4PST-NO standard, 47BND = 4PST-NO long-life, 48BND = high-reliability), coil voltage (5 / 12 / 24 VDC), and socket type. Within the 4-channel 24 VDC tier: G6B-4BND DC24V (this SKU) is the standard life version, G6B-47BND DC24V is the long-life 200,000-operation version, and G6B-48BND DC24V is the high-reliability version for safety-rated applications. Pick G6B-4BND DC24V for general-purpose interposing. Pick G6B-47BND DC24V for high-cycle use like machine-tool spindle on/off. Pick G6B-48BND DC24V for safety or critical applications.
Wiring and replacement
Each channel has separate coil input terminals (A1, A2 for channel 1) and separate contact output terminals (13/14 for channel 1 NO, etc.) on the screw-terminal block. The four channels share no commons — each is fully isolated, which is the main advantage of a 4-channel terminal relay over a single 4PDT relay. The plug-in G6B relay module can be pulled straight out and replaced in under 30 seconds without removing any wiring from the screw terminals. The LED on each channel lights when the coil is energised, giving immediate visual feedback that the control signal has reached the relay.
Common installation
In a PLC panel the G6B-4BND mounts next to the PLC output bank on the same DIN rail, with the four PLC output wires landing on the four coil input terminals and the four load wires on the four contact output terminals. In a SCADA / RTU cabinet the G6B-4BND provides field-side switching for four digital outputs, with LEDs giving a quick visual check of which channels are energised.

Buying Checklist
- Pick G6B-4BND DC24V for 4-channel standard-life interposing
- Pick G6B-47BND DC24V for 4-channel long-life high-cycle use
- Pick G6B-48BND DC24V for 4-channel high-reliability / safety-rated applications
- Pick G6B-4BND DC12V if your control signal is 12 VDC rather than 24 VDC
- Order P6B-Y1 yellow marking strips for channel labelling at commissioning
- Plan one spare G6B relay module per 10 channels in your spares cabinet for fast swap on service calls

FAQ for G6B-4BND DC24V
What is the difference between G6B-4BND and G6B-47BND?
Both are 4-channel terminal relays with 4PST-NO contacts at 5 A. The 4BND is the standard 100,000-operation electrical life version; the 47BND is the long-life 200,000-operation version for higher-cycle applications. Pick the 47BND for spindle on/off or pneumatic valve cycling; pick the 4BND for general-purpose interposing where cycles are low.
Can I replace a single failed channel without rewiring the whole block?
Yes — the G6B mini-relay module on each channel is plug-in. Pull the failed channel's relay module straight out of the P6B socket and push a fresh G6B relay module in. The wiring stays put. Replacement takes under 30 seconds per channel.
Are the four channels isolated from each other?
Yes — each of the four channels has its own coil input and own contact output, with no shared common. The dielectric strength between any two channels is 2,000 VAC for 1 minute. This is the main advantage of a 4-channel terminal relay over a single 4PDT relay: a fault on one channel cannot affect the other three.
What is the difference between G6B-4BND and G6B-48BND?
The 4BND is the general-purpose standard. The 48BND is the high-reliability version with more stringent quality control, intended for safety-rated or critical applications. Contact ratings and form are the same; the difference is in the manufacturing and testing process and the warranty.
