Built‑in function

AD908JQ breakout interconnect cable realizes signal transition between Foxboro FBM I/O modules and field‑side process wiring. High‑density D‑SUB converts to screw‑type terminal‑block,greatly facilitates on‑site wiring commissioning and later‑period module replacement. Shielded twisted‑pair structure suppresses industrial electromagnetic interference,ensures stable transmission of analog and digital signals for pressure,flow,temperature and liquid‑level loops in petrochemical,chemical and power‑plant DCS cabinets. Removable terminal‑block design avoids repeated wire disassembly when swapping FBM modules,reduces maintenance workload.

Product Brief

AD908JQ belongs to Foxboro I/A Series legacy DCS wiring‑accessory spare‑part family,obsolete original dedicated transition cable. Must pair with corresponding FBM I/O module. Widely used for original Foxboro DCS‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
