Product Overview
The Omron G3NA-D210B-UTU is a single-pole solid state relay for switching DC loads. It combines a 5–200 VDC load range, a 10 A rating when correctly heat-sinked, and a 5–24 VDC control input.
The screw-terminal body provides an operation indicator and can be panel mounted or adapted for DIN-rail mounting. This is a DC-output model: do not use it for an AC load.
Before ordering, confirm the actual load current, inrush, ambient temperature and heat-sink requirement from Omron's derating data. For the AC-output alternative in the same G3NA form factor, see G3NA-210B-UTU DC5-24.
Key Features
- Single-pole DC-output SSR rated 10 A with the required heat sink
- 5–200 VDC load voltage and 5–24 VDC control input
- Screw terminals and operation indicator
- Panel mounting; DIN-rail installation requires the appropriate adapter
- SKU: G3NA-D210B-UTU
- Series: G3NA solid state relays
- Voltage: 200 VDC
Best-Fit Applications
- Switching a DC solenoid or resistive load where frequent operation makes mechanical contact wear undesirable.
- Replacement of an existing G3NA DC-output SSR after matching the load voltage, current, control input and thermal design.
- Low-voltage machine control where a PLC or controller supplies a 5–24 VDC control signal.
Buying Checklist
- Choose this model only for DC loads; G3NA-D210B-UTU is not an AC-output relay.
- Size the heat sink from the actual continuous current and cabinet temperature, not from the 10 A headline rating alone.
- Match the complete part number and check the required mounting adapter or heat sink separately.

FAQ for G3NA-D210B-UTU
Can the G3NA-D210B-UTU switch an AC load?
No. This model is for DC loads. The related G3NA-210B-UTU DC5-24 is the AC-output variant; verify its own load and input ratings before substituting it.
Does the G3NA-D210B-UTU need a heat sink?
Use the heat sink required by Omron's load-current and ambient-temperature derating data. The 10 A rating is conditional on suitable heat sinking; do not treat it as a universal rating without one.
Does zero-cross switching apply to this DC-output model?
No. Zero-cross control is relevant to AC switching and should not be used as a selection claim for this DC-output SSR.
What should I check before replacing an existing relay?
Match the full model number, DC load voltage and current, control voltage, mounting arrangement and heat-sink design. A similar G3NA housing does not by itself establish compatibility.
