Product Overview
The Omron G3NA-D210B-UTU DC5-24 is Omron's 10 A DC-output Solid State Relay in the G3NA hockey-puck family, designed to switch DC loads such as solenoid valves, DC heating elements, brushless DC motor coils, and LED lighting arrays from a low-current DC control signal. manufactured by Omron Corporation. Hengyixin Automation stocks this solid-state relay in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
Unlike AC-output SSRs which use a triac and benefit from zero-cross switching, the G3NA-D uses a power MOSFET output stage that switches the DC load on and off cleanly in both directions — there is no AC zero-cross concept for DC loads. The G3NA family is Omron's hockey-puck-style SSR, sharing a uniform mounting pitch so panels can hold a mix of AC and DC output units without drilling new holes.
On a battery formation line, the same SSR switches the charging current to individual battery cells under test.

FAQ for G3NA-D210B-UTU DC5-24
What is the difference between G3NA-D210B and G3NA-210B?
The D prefix means DC output (MOSFET, bidirectional load terminals, no zero-cross concept); the plain G3NA-210B is AC output (triac, zero-cross switching for low-noise AC loads). Pick the D version for DC solenoids, DC heaters, DC motors, and battery switching; pick the AC version for AC solenoids, AC heaters, AC lamps, and any AC mains-driven load.
Does the G3NA-D210B-UTU DC5-24 have a built-in heatsink?
No — the G3NA-D210B-UTU ships as a panel-mount hockey-puck module that requires an external heatsink for continuous high-current operation. Omron's Y92B-P series DIN-rail heatsinks accept the G3NA footprint, or you can mount the SSR directly to a metal chassis with thermal compound. At 10 A continuous DC load, expect about 12 to 15 W of dissipation; at 5 A the unit runs cool without a heatsink.
Can the G3NA-D210B-UTU do PWM proportional control?
Yes — the MOSFET output stage switches in microseconds, so a PWM signal at the input (e.g. from a temperature controller) gives proportional DC output power to the load. Typical PWM frequencies are 100 Hz to 1 kHz for DC heaters; for DC solenoid valves use on/off control rather than PWM to keep the valve fully seated or fully released.
Is the G3NA-D210B-UTU polarity-sensitive on the load side?
No — the MOSFET output stage is bidirectional, so you can connect either polarity of the DC load to terminals 1 and 2. The control input (terminals 3 and 4) is polarity-sensitive: connect +24 VDC to terminal 3 (+), 0 VDC to terminal 4 (-). Reverse input polarity will not turn on the LED and the SSR will not switch the load.
