Installation Guidelines

First, power down the control system completely before installation.
Insert the Woodward 5441-693 into the card guides carefully.
Push the module firmly until the motherboard connectors engage.
Secure the module using the top and bottom mounting screws.
Connect field wiring to the 24 optically isolated input terminals.
Connect output devices to the 13 relay circuit terminals.
For relay outputs, observe the maximum current ratings.
Use appropriate suppression for inductive loads on relays.
Verify the 24 Vdc contact supply provides 400 mA maximum.
After installation, power up and verify module communication.

Wiring Recommendations

Use copper cables with 0.5 to 1.5 mm² cross section for inputs.
For relay outputs, use cable rated for the connected load current.
Keep input wiring separate from high-power AC cables.
Use shielded cables for long input runs in noisy environments.
Label each of the 24 input channels clearly for identification.
Label all 13 relay output circuits according to your drawing.

Frequently Asked Questions (FAQ)

1. Can the 5441-693 be used as a standalone controller?

No, the Woodward 5441-693 requires a PLC or DCS system. It functions as a remote I/O module, not a standalone controller.

2. What is the maximum switching frequency for the relays?

The 5441-693 relay circuits are for general purpose control. For high-speed switching, consult the Woodward technical manual for specific ratings.

3. Are the input channels compatible with AC voltages?

No, the Woodward 5441-693 inputs are for 24 Vdc only. AC inputs require an external conversion or a different module.

4. How do I know which communication protocol to use?

Check your PLC system's compatibility first. The 5441-693 typically supports Modbus, Profibus, and Ethernet/IP.

5. Can I replace a faulty relay on this module?

Individual relays are not field-replaceable on the Woodward 5441-693 . The entire module must be replaced or sent for factory repair.
