Foxboro E100T15F Hazardous-Area Power Module

Product Description

The Foxboro E100T15F is an industrial-grade field-mounted power module engineered for hazardous-area installations. It delivers precision-regulated 15 VDC power from a wide-range AC input (95–265 VAC), providing stable, isolated energy for two-wire transmitters and field instrumentation. Its low-noise output ensures accurate operation of 4–20 mA, HART, and Fieldbus devices.

Constructed for extreme conditions, the E100T15F features an IP66-rated enclosure for dust and water protection, advanced overvoltage, undervoltage, and overcurrent safeguards, and high thermal resilience. It is suitable for offshore platforms, chemical plants, refineries, outdoor substations, and high-vibration environments. The module can be mounted on walls or pipes for versatile field deployment.
