SL150 — Explosion Proof GRP Status Light
The SL150 is a flameproof status light column for potentially explosive atmospheres. ATEX and IECEx certified for gas and dust zones and SIL2 compliant, it stacks two to five signalling units on a single 316L stainless steel backplate to indicate several process states at once.
Each unit uses a Glass-Reinforced Polyester housing with a UV-resistant coating with a borosilicate glass lens, optionally protected by a 316L stainless steel guard. Beacons can be triggered jointly or independently, and one beacon can be replaced by a push button or junction box. LED runs flashing, static or rotating at 60–120 FPM; xenon flashes at 60–180 FPM. Ambient range is −40°C to +70°C.
For a 316L stainless steel enclosure, see the SL125.
Typical applications: oil and gas, petrochemical, chemical plants, offshore platforms, refineries, hazardous-area process control.
