✅ Typical Applications

PLC DC output expansion, elettrovalvole, spie luminose, DC motors and other small DC loads. Ideal for space-saving high-density wiring inside control cabinets; contact-free, no arcing, far longer service life than electromagnetic relays.

-Nota: For DC loads only, cannot switch AC loads (Select A / AL for AC output)

✅ Replaceable SSR Insert Spare Parts

Internal SSR insert can be replaced separately: G3RV-D03SL (for standard D); high-speed -H insert: G3RV-D03SL-H

✅ Series Quick Selection Chart

G3RV-ST700-D: DC MOSFET output, 3 UN, terminali a vite

G3RV-ST700-D-H: High-speed DC, 0.2 ms operate, for high-frequency pulse applications

G3RV-ST700-A: AC TRIAC output, zero-cross, 2 UN

G3RV-ST700-AL: AC TRIAC output, non-zero-cross, 2 UN (for phase control)

Suffisso 500 = Push-In spring terminals, reduces wiring time

✅ Troubleshooting Guide

Output permanently ON: MOSFET breakdown, usually caused by overload or back EMF surge (freewheeling diode must be fitted in parallel for inductive DC loads)
Input LED ON but no output: Check load polarity; or load current below 100 μA minimum load (unstable for micro-loads)
Excessive heat: Sovracorrente, temperatura ambiente elevata, dense side-by-side mounting; leave ventilation gaps
Indicator lamp faintly lit due to leakage current: Leakage of D-type is already minimal; check common-ground interference if issue persists

MOSFET DC SSR, switches only DC5~24 V loads, massimo 3 UN, 6.2 mm ultra-slim DIN rail mount, contact-free, no spark, lunga durata, screw terminal variant, designed mainly for high-density cabinet PLC interface isolation output

Non-Standard Automation Equipment (Primary Use Case)
PLC DC output port isolation expansion: Native PLC DO ports have limited load capacity. This SSR isolates and amplifies signals to drive DC24 V loads; supports NPN/PNP signal conversion and potential isolation between different circuits to protect PLC outputs.
DC24 V solenoid valve drive: Pneumatic solenoids, generatori di vuoto, low-power proportional valves. Contact-free design suits frequent switching, eliminating contact burnout and welding issues common with mechanical relays.

-✅ For inductive loads: Fit freewheeling diode parallel to solenoid coil

Indicator lights, stack lights, station beacons, alarm lamps (DC24 V): Multi-channel dense output cabinets for space saving.
Small DC electromagnets, magnetic holders, clamping cylinder solenoids.
Semiconduttore & Attrezzatura per batterie al litio (Alta frequenza, Dust-free Requirements)

Semiconductor testers, probe stations, lithium sorting machines, cell testers, pole piece equipment:

Dust-free workshops require no electric arcs / dust tracking from mechanical contacts, SSR’s spark-free operation fits perfectly.

High-density I/O cabinets with massive I/O points; 6.2 mm slim form factor is a major advantage.

Standard version for normal cycle rates; -H high-speed variant for high-frequency pulse control and high-speed sorting triggering.

III. Confezione, Logistica & Sistemi di trasporto

Drive DC24 V stoppers and sorting gate electromagnets after position detection on conveyors;

DC indicator lamps and trigger light sources for barcode scanners & sistemi di visione;

Multi-channel signal isolation for sorters, palletizing auxiliary machines and labellers.

Test Jigs & Burn-in Racks

PCBA burn-in racks, harness test fixtures, BMS test benches for multi-channel DC load switching;

Suitable for micro-load applications (minimum load down to 100 μA): controls miniature sensor supply loops and tiny indicators, where conventional SSRs often fail to turn off micro-loads cleanly.

Macchina utensile & 3C Processing Equipment

CNC auxiliary machines, macchine perforatrici, smerigliatrici, fixture tooling:

Bloccaggio dell'attrezzatura / positioning electromagnets, DC24 V coolant pumps, low-power DC cooling fans;

Machine I/O cabinets with tight space constraints; multiple units mounted side-by-side to replace wider conventional relays.

Other General Industrial Control Scenarios
Low-power DC24 V actuators and electric dampers in building / HVAC control cabinets;
Auxiliary DC24 V signal loops for access control and safety gates (NOT safety-rated safety relays, only ordinary signal circuits);
Robot peripheral jigs, fixture I/O junction boxes and distributed terminal signal isolation.

✘ Unsuitable Applications (Important Warnings)

High-power DC motors, loads exceeding 3 UN
Safety stop, safety gate monitoring and other safety-related circuits (cannot replace Fungo O OMRON G9SX safety relays)
All'aperto, heavily corrosive, high-shock / high-vibration harsh environments
