Honeywell 05701‑A‑0326 System 57 Field Interface Card

Description

Product Overview

The Honeywell 05701‑A‑0326 is a field‑interface plug‑in card designed for Honeywell Zellweger System 57 rack‑mount gas‑detection monitoring system. It provides dedicated wiring terminals for field gas‑detector cables, implements signal isolation and transient‑surge protection between field‑side sensors and internal single‑channel control cards. This card undertakes all field‑cable termination work, separates field‑wiring from the expensive main control card, avoids control‑card damage caused by field‑loop surge, short‑circuit or wiring‑fault. It adopts 3U standard plug‑in mechanical structure, installs into System 57 19‑inch sub‑rack, works cooperatively with 05701‑A‑0301 or 05701‑A‑0302 single‑channel gas‑detection control cards. Widely used for legacy System 57 gas‑monitoring‑system maintenance and spare‑part‑replacement projects for petrochemical, refinery and offshore‑platform sites.

Series

System 57 modular fire‑and‑gas safety‑monitoring hardware platform by Honeywell Zellweger Analytics. The rack‑based system includes gas‑detection control cards, field‑interface cards, relay output cards, DC‑input power‑interface cards and backplane assemblies for continuous toxic‑gas and combustible‑gas safety‑monitoring in industrial‑hazardous‑location cabinets.

Product Features

1. Dedicated field‑interface wiring termination for gas‑detector field‑cable connection
2. Built‑in transient‑surge‑protection circuit, protects downstream single‑channel control‑card hardware from field‑side surge‑voltage damage
3. Electrical‑isolation design separates field‑loop and rack‑internal‑circuit to restrain ground‑loop interference
4. Matches perfectly with System57 single‑channel control cards (05701‑A‑0301 / 05701‑A‑0302)
5. All field‑cables terminate onto this interface card; main control‑card avoids direct contact with field‑wiring fault risks
6. 3U plug‑in form‑factor, directly inserts into System 57 standard 19‑inch sub‑rack chassis
7. Supports hot‑swap replacement; replacement does not affect other channel operation inside the rack
8. Industrial‑grade hardware design for long‑term 24‑hour continuous‑operation inside safety‑monitoring cabinets
