5503-279
WOODWARD 5503‑279 is a High‑Density Versatile Input Module (HDVIM) of the MicroNet control series, manufactured by Woodward, USA. It is a high‑density multi‑type analog signal acquisition card, specially used for MicroNet/MicroNet Plus turbine and generator control systems, responsible for collecting temperature, pressure, flow, speed and other field analog signals, and transmitting data to the CPU through the VME bus. It supports simplex and redundant control systems, and is widely used in power generation, petrochemical, marine power and compressor control systems.
Description
Product Details
This module has 34 configurable analog input channels + 2 cold‑junction compensation inputs, supporting 4‑20 mA current signals, thermocouple (TC) and RTD thermal resistance signals. The front 12 channels are isolated in groups, effectively resisting electromagnetic interference and ensuring high‑precision signal collection.It adopts industrial‑grade isolation design, with wide‑temperature working range and strong anti‑vibration performance. Plug‑in modular structure is compatible with MicroNet control chassis, supporting hot‑swap, built‑in signal self‑diagnosis and fault alarm functions, realizing real‑time monitoring of field equipment operating status.
