Foxboro P0916AW Universal Mixed Analog I/O Module for I/A Series DCS Process Control

The Foxboro P0916AW is a high-performance universal analog mixed input/output module belonging to Foxboro I/A Series distributed control system, serving as the core signal interface between field sensors, actuators and DCS host stations. Equipped with 16-bit high-precision ADC conversion chip, it supports flexible channel configuration (each channel switchable between analog input AI and analog output AO). Compatible with mainstream field signal types including 4-20mA, 0–10V, ±10V, RTD and thermocouple, it achieves full-span measurement accuracy of ±0.1%. It adopts 1500V AC channel-to-channel galvanic isolation design, with common-mode rejection ratio over 120dB, effectively suppressing strong electromagnetic interference in industrial sites. Powered by backplane 24VDC, power consumption is less than 5W. It integrates built-in signal filtering, overrange protection, channel fault self-diagnosis and PID auxiliary control functions. Equipped with detachable terminal blocks and independent LED status indicators for each channel, supporting hot swapping without system shutdown. It has passed UL, CE, ATEX and SIL 2 safety certifications, with a wide operating temperature range of -25℃ to +70℃, stable operation under G3-level dusty and corrosive industrial environments.
