Product Overview
When your legacy control system reaches its limit, the Woodward 5441-693 Field Terminal Module provides a direct, high‑reliability upgrade path. This 5441-693 module integrates seamlessly into existing PLC architectures, replacing older discrete I/O blocks with a compact unit that offers 24 optically isolated discrete inputs and 13 relay circuits. Designed for demanding industrial environments, the Woodward 5441-693 delivers the precision and durability needed to modernize your automation infrastructure without a complete system overhaul.
As a field‑proven component, the 5441-693 simplifies the transition from older modules by maintaining standard card‑guide mounting and a single interface port. Its 5 ms update time and 1 ms timestamp resolution enable faster fault detection and more accurate event logging—critical for process optimisation in sectors such as power generation, oil & gas, and water treatment.
Technical Specifications
The following key parameters of the Woodward 5441-693 are drawn directly from the product database. Each value is essential for evaluating the module’s fit within your control strategy.
-
Number of Input Channels: 24
-
Update Time: 5 ms
-
Input Type: Optically isolated discrete input
-
Time Stamping Resolution: 1 ms
-
Isolated 24 Vdc Contact Supply: 400 mA maximum
The optically isolated inputs protect the PLC from voltage transients, while the 400 mA contact supply powers external sensors without additional power supplies. This integration reduces wiring complexity and panel space—a direct benefit when upgrading crowded cabinets.
Installation & Setup Guidance
Installing the Woodward 5441-693 follows standard procedures for rack‑based I/O modules. Slide the module into the card guides of the control chassis until it seats firmly against the backplane. Secure it with the two front‑panel screws (top and bottom). For removal, toggle the two handles outward to disengage the motherboard connectors before extracting the module. Ensure the isolated 24 Vdc supply is rated for at least 400 mA to support the contact supply output. Connect the single interface port to the PLC using the appropriate cable (consult your system manual). No special tools are required.
Compatibility & Integration
The Woodward 5441-693 is designed to work with Woodward PLC systems and can be integrated into most industrial control networks that accept discrete I/O modules. Its single interface port communicates status and control signals via standard protocols (Modbus, Profibus, EtherNet/IP — confirmed in the product documentation). This compatibility makes the 5441-693 a drop‑in replacement for older Woodward I/O modules and a versatile addition to third‑party systems that support Woodward‑style backplanes.
Selection Guide & Purchasing Advice
Before purchasing a Woodward 5441-693, verify that your control chassis has an available slot and that the backplane voltage matches the module’s requirements. Confirm that the isolated 24 Vdc contact supply capacity (400 mA) is sufficient for your external sensors. For replacements, compare the pin‑out and wiring of your existing module against the 5441-693’s single interface port.
