Product Overview
The Omron G3NA-210B-UTU DC5-24V is a 10 A solid state relay from the G3NA series, manufactured by Omron Corporation. Hengyixin Automation stocks this solid-state relay in Xiamen and ships within 3-5 business days in original Omron packaging with the lot code visible.
The relay switches a 24-240 VAC load (operating range 19-264 VAC) at 10 A rated, single-pole SPST-NO. Control input is 5 to 24 VDC at 7 mA max, with a must-operate voltage of 4 V max and a must-release voltage of 1 V min. Switching is zero-cross to limit electrical noise on the AC line. Output ON voltage drop is 1.6 V RMS max.
Phototriac coupler isolation between the DC control circuit and the AC load. Built-in varistor absorbs external surges. The 58 x 43 x 27 mm hockey-puck body mounts to a panel with screws. Heat sink is required for continuous full-load operation. The G3NA-D210B-UTU sibling switches DC loads 5-200 VDC; the G3PA-220B-VD-X is the 3-phase 20 A equivalent.
Key Features
- G3NA-series solid state relay, 1-pole SPST-NO, 10 A rated load current at 24-240 VAC (operating range 19-264 VAC)
- 5 to 24 VDC control input, 7 mA max control current, must-operate 4 V max, must-release 1 V min
- Zero-cross switching, phototriac isolation, built-in varistor surge absorber, 1.6 V RMS max output ON drop
- Hockey-puck panel-mount, 58 x 43 x 27 mm, LED operation indicator, -30 to +80 C operating
- SKU: G3NA-210B-UTU DC5-24V
- Series: Omron G3NA-series solid state relay
- Voltage: 24 TO 240 VAC
Best-Fit Applications
- Resistive heater band control on a plastic injection molding extruder barrel driven by a 24 VDC PLC temperature controller through PWM at high cycle rates
- Shrink-wrap tunnel seal bar heater where zero-cross switching keeps electrical noise low on a 10 A 240 VAC load controlled from a 5 VDC signal
- Spare replacement on a packaging panel where the previous 10 A SSR has failed and a like-for-like hockey-puck relay is needed on the same footprint
Buying Checklist
- Pick the G3NA-210B-UTU DC5-24V for a 10 A 24-240 VAC solid state relay driven from a 5-24 VDC control signal with zero-cross switching.
- Pick the G3NA-D210B-UTU instead when the load is a DC circuit at 5-200 VDC, such as a DC heating element or DC solenoid.
- Pick the G3PA-220B-VD-X instead when the panel needs a 3-phase 20 A solid state relay with built-in heat sink.

FAQ for G3NA-210B-UTU DC5-24V
What is the Omron G3NA-210B-UTU DC5-24V used for?
It is a panel-mount solid state relay for ON/OFF switching of a 24-240 VAC load at 10 A, such as resistive heaters, lighting arrays, or small motors. The 5-24 VDC control input is driven directly from a PLC sourcing output.
Does the G3NA-210B-UTU DC5-24V need a heat sink?
For continuous duty at the full 10 A rating, yes - a heat sink is required to keep the case within its -30 to +80 C rating. For intermittent or low-current loads below 4 A no heat sink is needed and the relay can operate at full rated life.
G3NA-210B-UTU vs G3NA-D210B-UTU - what is the difference?
The G3NA-210B-UTU switches AC loads 24-240 VAC at 10 A. The G3NA-D210B-UTU switches DC loads 5-200 VDC at 10 A. Both share the same hockey-puck body and 5-24 VDC control input.
Is the G3NA-210B-UTU zero-cross switching?
Yes. The UTU model is zero-cross, which means the relay turns the AC load on at the next zero-voltage crossing of the AC line. This reduces inrush current and electrical noise for resistive and lightly inductive loads.
How does the G3NA-210B-UTU isolate the control circuit from the load?
Phototriac coupler isolation between the DC control input and the AC load. The unit also carries a built-in varistor that clamps surge voltage from the AC line to protect downstream components.
