Product Overview
The Omron G6D-F4B DC24V is Omron's 4-point terminal relay in the G6D family — four SPST-NO mechanical relays in a single 31 × 35 × 68 mm package with screw terminals, LED indicators, and built-in coil-surge diodes. manufactured by Omron Corporation. Hengyixin Automation stocks this relay in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The right pick when you need four independent relay outputs on a DIN rail panel with field-side wiring that should be quick (screw terminals) and PLC-friendly (24 VDC coil, low 200 mW power per relay). It is a true terminal relay — the relays are mounted on a captive PCB inside the housing, and the screw terminals are at the field side for easy wire landings.
For higher-current DC coils (>50 mA), consider the G6B-4BND DC24V which has higher 70 mA coil current for larger mechanical relays.
Key Features
- 24 VDC coil
- Compact form factor 31 × 35 × 68 mm
- G6D series 4-point terminal relay
- 4× SPST-NO mechanical contact sets
- SKU: G6D-F4B DC24V
- Series: G6D Terminal Relays (4-point SPST-NO 5 mm × 20 mm × 12.5 mm mini-relay)
- Voltage: 24 VDC
Best-Fit Applications
- 24 VDC PLC output expansion to 230 VAC loads — the G6D-F4B relays accept 24 VDC from CJ1W-OD211 / OD212.
- Indicator lamp driver on a control panel — 4 relays each switching a 24 VDC / 120 / 230 VAC.
- Isolated interface between PLC and external equipment — the G6D-F4B provides galvanic isolation between the PLC's 24 VDC logic and.
Buying Checklist
- Pick G3DZ-F4PU DC24V for Push-In Plus MOSFET version — combine fast wiring + silent switching
- Pick G6D-F4PU DC24 for Push-In Plus terminals — if you want tool-free wiring instead of screw
- Pick G3DZ-F4B DC24V for 4× SPST-NO 0.1 A MOSFET output — for silent high-cycle low-current switching

FAQ for G6D-F4B DC24V
Can the G6D-F4B DC24V be driven from a NPN sinking PLC output?
Yes — the G6D-F4B DC24V 24 VDC coil is polarity-sensitive (because of the internal flyback diode). For NPN sinking PLC output (e.g., CJ1W-OD211): connect the PLC output to the coil '+' terminal of the G6D; connect the coil '-' terminal to the 24 VDC supply positive rail. The NPN output sinks current from the coil + to ground when ON, completing the 24 VDC → coil+ → NPN → GND circuit.
How do I tell the difference between G6D-F4B, G6D-F4PU, and G3DZ-F4B?
All three are 4-point terminal relays in similar form factor with 24 VDC coils, but differ in contact type and wiring method. G6D-F4B (this SKU) uses mechanical SPST-NO relays with screw terminals, 3 A / 250 VAC per contact. G6D-F4PU uses mechanical SPST-NO relays with Push-In Plus terminals (tool-free ferrule-direct wiring), same 3 A contact rating as F4B but faster wiring.
What is the G6D-4-SB Short Bar and when do I need it?
The G6D-4-SB Short Bar (sold separately, pack of 5) is an accessory that bridges adjacent same-polarity terminals of a G6D-F4B / G6D-F4PU / G3DZ-F4B housing.
Can the G6D-F4B drive 230 VAC inductive loads like solenoid valves?
Yes — the G6D-F4B's SPST-NO contacts are rated 3 A at 250 VAC, suitable for switching 230 VAC solenoid valves, contactor coils, and small motor windings. Add surge suppression across the AC load (typically a 275 V MOV or an RC snubber across the AC coil terminals) — the G6D-F4B's contacts have no internal surge protection, unlike the coil side which has a flyback diode.
