At HONGKONG XIEYUAN TECH CO. LTD, reliable automation begins with clean, protected signals. Our GMI D9000 Series Surge Arresters are purpose-built to stop lightning and switching transients before they travel from the field into your control room. Engineered for Oil & Gas, petrochemical, steel and other heavy-duty industries, these arresters keep 4-20 mA, digital, RTD and bus signals intact while safeguarding DCS, PLC and SCADA hardware. Where a single strike can cost days of downtime, the D9000 series gives you the surge immunity your operation demands.

Why Choose the GMI D9000 Series

When outdoor cables enter control cabinets, surge energy is inevitable. The D9000 family absorbs it—repeatedly—without degrading measurement accuracy or safety.

Here’s what makes them stand out:

● Multi-Stage Protection – Gas tube + MOV + diode matrix clamps surges to <40 V, regardless of waveform or energy level.

● Industry-Rated Housing – IP20 finger-safe, DIN-rail mountable, -40 °C … +80 °C certified for desert sun or arctic cold.

● Threaded or Plug-In Terminals – Maintenance-free spring-clamp or M3 screw options; hot-swap modules without breaking the loop.

● Wide Signal Compatibility – Covers 4-20 mA, 0-10 V, thermocouple, RTD, HART, Modbus, Profibus PA, Foundation Fieldbus and NAMUR sensors.

● Fail-Safe / End-of-Life Indication – Visual flag and optional dry-contact tell you exactly when replacement is due—before the next storm.

These arresters are designed to eliminate nuisance trips and keep your control room assets alive.

Cleaner Signals with GMI Surge Arresters
Our D9000 units install at the cable entry point—marshalling cabinet, junction box or field device—creating a “surge firewall” between the plant and sensitive electronics. They help maintain SIL loops, custody-transfer accuracy and communication uptime even during severe weather.

You can deploy them on hundreds of I/O without adding panel depth, shrinking overall surge-risk metrics for insurance and compliance audits. For reliability engineers who need measurable MTBF improvement, these devices deliver quantified protection in every volt.

Compact and Capable D9000 Variants

The D9000 family is ideal for high-density panels where space, weight and heat dissipation matter. Each module merges heavy-duty surge capacity with micro-second response, making specification and stocking straightforward. The 6 mm single-channel, 12 mm dual-channel and 22 mm trunk versions share accessories and mounting, so you scale protection without redesign.

Some of its user-friendly features include:

● Color-Coded Voltage Classes – 24 VDC, 48 VDC, 120 VAC and 230 VAC variants prevent wiring mix-ups

● Integrated Shield Grounding – Clamps shield to earth through the same foot-print, eliminating extra terminals

● ATEX / IECEx Non-Sparking Approval – Safe to use in Zone 2 / Div 2 locations when installed in appropriate enclosure

These features make the series a dependable choice for brown-field upgrades and green-field projects alike.

Simple Integration and Certified Performance

Incorporating D9000 arresters into your infrastructure is effortless. Each unit ships with IEC 61643-21 test certificates, impedance curves and ready-to-insert CAD symbols. You can upgrade surge immunity while preserving existing cable schedules and cabinet layouts.
