Product Model: WOODWARD 5441-695

Brand: WOODWARD (Woodward)

Product Type: MicroNet / NetCon 5000 Series DataForth Analog Field Terminal Module (DataForth Analog FTM Module)

Generation Time: 2026-05-18 11:40:27

I. Product Overview

WOODWARD 5441-695 is a high-precision analog signal conditioning and interface module specifically designed for the MicroNet and NetCon 5000 control systems. As an FTM (Field Termination Module), it integrates the DataForth SCM7B series isolation signal converter, which is tailored to convert complex on-site sensor signals such as thermocouples, RTDs, millivolts, 4-20mA, etc., into standard voltage signals (0-5V) that can be recognized by the control system. This module is a discontinued model, and the market mainly circulates refurbished / spare parts. 

II. Core Functional Characteristics

DataForth Isolation Technology: Built-in plug-in DataForth SCM7B signal conditioning module, providing full isolation between channels and extremely strong anti-interference capability.

24/8 High-Density Analog I/O: Offers 24 analog input (AI) channels and 8 analog output (AO) channels. High-density design, saving rack space.

Universal Signal Input: By replacing the SCM7B module, it can be adapted to thermocouples (J/K/T/E/S/R/B types), RTD (Pt100/Pt1000), 4-20mA, 0-10V, millivolt signals.

No Calibration Design: Both the FTM base and the SCM7B sub-module are of no-calibration design, plug-and-play, and maintenance is simple.

Channel Independent Configuration: The 24 input channels are completely independent. Each channel can be independently configured with different signal types, with extremely high flexibility.

Full Electrical Isolation: 2500V AC three-terminal isolation for input, output, and system side. Effectively protecting the control system from on-site surges and interference.

Standard FTM Specifications: Compatible with MicroNet standard rack, supports hot swapping, and installation and replacement are convenient.

Industrial-grade Reliability: Wide temperature, shock-resistant design, compliant with CE, UL certifications, suitable for high-precision measurement and control scenarios in power plants, petrochemicals, etc.
