Woodward 5441-693 Field Terminal Module 24 Ch

Woodward 5441-693 Field Terminal Module

Product Introduction

The 5441-693 is a high-performance discrete input module designed by Woodward for critical control applications. It provides 24 optically isolated input channels with an update time of just 5 ms. Each channel supports time stamping at 1 ms resolution, which makes it ideal for event sequencing and fault diagnostics.

This module also includes an isolated 24 Vdc contact supply rated at 400 mA maximum. The 5441-693 mounts directly into a Woodward control chassis using card guides and motherboard connectors. Two screws and toggle handles secure the unit and simplify removal.

Additionally, this module is currently in stock and available for fast delivery via Fedex, UPS, or DHL. Its country of manufacture is the United States (USA).

Technical Specifications

Input Characteristics

The 5441-693 features 24 discrete input channels with optical isolation. This design protects the control system from electrical noise and voltage spikes. Each channel detects on/off states from field devices such as limit switches, pushbuttons, and proximity sensors.

• Number of input channels: 24

• Update time: 5 ms

• Time stamping resolution: 1 ms

• Input type: Optically isolated discrete input

Power Supply Details

An integrated 24 Vdc contact supply powers external field contacts. This supply is isolated and delivers up to 400 mA. Therefore, users do not need a separate power source for dry contact inputs.

• Isolated 24 Vdc supply: 400 mA maximum

General Specifications

• Part Number: 5441-693

• Manufacturer: Woodward

• Product Type: Field Terminal Module

• Repair time: 3–7 days

• Availability: In Stock

• Country of Manufacture: United States (USA)

Mechanical and Environmental Parameters

The 5441-693 uses a rugged form factor suitable for industrial control cabinets. Its front panel includes two handles and two screw locks. When you push the handles outward, the module disengages from the motherboard connectors. This feature simplifies maintenance without special tools.

• Mounting: Horizontal card guides inside Woodward chassis

• Securing: Top and bottom front screws

• Removal: Toggle handles for easy extraction

• Dimensions: Standard Woodward module height

• Operating temperature: 0 to +60 °C (typical industrial range)

• Storage temperature: -40 to +85 °C

Furthermore, the module’s optical isolation provides 1500 Vrms withstand voltage between field and logic side. As a result, it performs reliably in electrically noisy environments like power plants and manufacturing lines.

Installation Guide

Follow these steps to install the 5441-693 correctly:

1. Power down the control chassis completely.

2. Insert the module into the appropriate card guide slot.

3. Slide the unit toward the motherboard until resistance is felt.

4. Push the top and bottom toggle handles inward to fully seat the connectors.

5. Tighten the two front panel screws (top and bottom).

6. Connect external field wiring to the terminal blocks.

7. Apply power and verify input status via the PLC system.

Important: Do not force the module if it does not seat properly. First, check for bent pins or misaligned card guides. Additionally, always observe electrostatic discharge (ESD) precautions during handling.

Frequently Asked Questions (FAQ)

1. What PLC systems work with the 5441-693?
This module integrates with Woodward programmable logic controllers and compatible control systems using discrete input signals. It is not designed for Allen-Bradley or Siemens racks directly.

2. Can I use the 5441-693 for high-speed counting?
No. The 5441-693 provides 5 ms update and 1 ms timestamping, but it lacks dedicated high-speed counter inputs. For fast pulse trains, use a specialized counter module instead.

3. Does the 5441-693 support hot swapping?
Woodward does not recommend hot swapping this module. Always power down the chassis before inserting or removing the 5441-693 to prevent damage.

4. How do I troubleshoot a non-responsive input channel?
First, verify the external field contact is closing correctly. Next, measure the 24 Vdc supply from the module’s isolated output. Finally, check the motherboard connection by reseating the module.

5. Is repair service available for the 5441-693?
Yes. Woodward offers repair services with a typical turnaround of 3–7 days. Contact an authorized service center for RMA procedures.
