Description
Product Overview
The Woodward 5441-693 is a high-density analog I/O module designed for integration with Woodward’s ProAct® series of distributed control systems. This rugged industrial module provides 16 channels of configurable analog input/output with 24-bit resolution and galvanic isolation, making it ideal for precision monitoring and control in power generation, oil & gas, and heavy industrial applications. The 5441-693 supports universal channel configuration, allowing each point to be independently programmed as voltage (0-10V), current (4-20mA), thermocouple, RTD, or resistance input. Its dual-redundant fieldbus communication (Profibus DP and Modbus RTU) ensures reliable data transmission even in electrically noisy environments. Built to withstand extreme conditions (-40°C to +85°C operating temperature, 5G vibration), the module features conformal-coated electronics and gold-plated connectors for maximum reliability in mission-critical control systems.

WOODWARD 5441-693
Main Features and Advantages
Universal channel flexibility: Each of the 16 channels on the Woodward 5441-693 can be individually configured through software as analog input or output, supporting 9 different signal types without hardware changes. This dramatically reduces spare parts inventory requirements.
Advanced signal conditioning: The module features 24-bit Σ-Δ ADCs with programmable low-pass filtering (1Hz to 10kHz) to eliminate noise in sensitive measurements. Built-in lead resistance compensation for RTDs and cold junction compensation for thermocouples ensure laboratory-grade accuracy in field conditions.
Fault-tolerant architecture: Dual self-monitoring power supplies and watchdog timers guarantee continuous operation. The 5441-693 implements channel-level diagnostics that detect open circuits, shorts, and out-of-range conditions, triggering configurable alarms in the control system.
Seamless system integration: Native support for Profibus DP-V1 enables cyclic and acyclic communication, while the dual-port RS-485 interface allows daisy-chaining of multiple modules. The Woodward 5441-693 automatically synchronizes with ProAct® controllers for deterministic control loop execution.

Installation and Maintenance
Pre-installation preparation: Verify grounding integrity (<1Ω to chassis ground) and cable shielding (90% coverage minimum). Configure Profibus node addresses and baud rates before power-up. Allocate 50mm clearance for heat dissipation in high-density panels.
Maintenance recommendations: Perform annual calibration verification using NIST-traceable references. Clean DIN rail contacts every 2 years with electronic-grade cleaner. Monitor channel drift statistics via embedded diagnostics to predict sensor degradation. The 5441-693 supports hot-swapping when using redundant communication paths.
