Telematic SD32X‑Intrinsically‑Safe Surge Protection Barrier

Product Overview

SD32X is DIN‑rail‑mount surge‑protection barrier for intrinsically‑safe instrument signal circuits. It suppresses lightning‑induced surge voltages and currents on 32 V field instrument loops, protecting transmitters, sensors and I/O modules from transient over‑voltage damage. Low series‑resistance design preserves measurement‑signal integrity, avoiding signal distortion for analog and digital instrument wiring in hazardous locations.
