Built‑in function

B0142CE analog signal‑processing PCB assembly serves as internal core replacement spare for Foxboro Spec‑200 series plug‑in modules. It completes amplification,filtering and conditioning for various weak‑level process signals. Factory pre‑calibration reduces debugging workload during on‑site maintenance. Built‑in surge‑protection circuit improves anti‑interference performance for complex industrial sites. It can restore measurement and conversion function for aging Spec‑200 I/O and signal‑conversion modules,widely applied for hardware repair of petrochemical,chemical and power‑plant legacy DCS cabinets.

Product Brief

B0142CE belongs to Foxboro Spec‑200 legacy DCS internal‑circuit‑board spare‑part family,obsolete original calibrated PCB assembly. It is an internal component and must be assembled into corresponding Spec‑200 module housing. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during handling and installation.
