Product Overview

The 5464-654 is a Discrete Output Module developed by Woodward. This module belongs to the MicroNet control family. The 5464-654 provides discrete outputs to the prime mover from field wiring. Each Discrete Output (DO) module can independently control outputs in response to CPU module commands. The module lacks potentiometers and does not require any calibration. Consequently, a module can be replaced with another module having the same part number without modifications. The 5464-654 is manufactured in the United States (USA).

Module Identification and Features

NETCON: 5000
Type: D/O (Discrete Output)
Port type: Dual port
Mounting type: Panel mount
Fault indication: Red fault indication LED

The 5464-654 includes a red fault indication LED for quick diagnostics. Furthermore, the module features a dual port design for flexible connectivity. The 5464-654 mounts directly to a panel using the provided hardware. Therefore, installation and replacement are straightforward tasks for maintenance personnel.

Output and Interface Characteristics

The 5464-654 receives digital data from the CPU and generates relay driver signals. However, these signals are not isolated. Consequently, the system's discrete output modules all interface to one or more Woodward Relay Modules. The relays' contacts are then connected to the field wiring. This design provides reliable switching for prime mover control applications. The 5464-654 module does not provide the relay power source directly.

Power Supply Requirements

The relays require a separate 24 Vdc power source for operation. The 5464-654 does not supply this power internally. As long as sufficient current is available, you can use a section of a multi-output Main Power Supply. Alternatively, power from a single-output Main Power Supply can also be used. Therefore, you must plan your power distribution accordingly when using the 5464-654 in your control system.

Cabling and Connectivity

Each 5464-654 module links to a Relay module via one low density discrete cable. This cable is then daisy chained to a second module via another low density cable. As a result, you can connect multiple modules with minimal wiring. The dual port design supports this daisy chain configuration efficiently. Consequently, the 5464-654 reduces overall cabling complexity in larger MicroNet systems.

Installation Guidelines

1. First, insert the 5464-654 into the card guides within the control chassis.
2. Then, push the module firmly to connect it to the motherboard.
3. Next, tighten the two screws at the top and bottom of the front panel.
4. These screws hold the 5464-654 securely in place.
5. To remove the module, loosen both front panel screws first.
6. After that, toggle the two handles outward (push them outward).
7. This action moves the 5464-654 out just far enough to disengage the motherboard connectors.
8. Subsequently, connect the low density discrete cable to the Relay module.
9. Finally, daisy chain to a second module using another low density cable.

Failure Behavior and Safety Features

The 5464-654 includes a critical safety feature for system faults. If communications with the CPU is lost, all outputs are turned off automatically. This fail-safe behavior prevents uncontrolled operation of the prime mover. Therefore, the 5464-654 enhances overall system safety during communication failures. The red fault indication LED provides immediate visual confirmation of any module fault condition.

Common FAQ

1. Does the 5464-654 require calibration before use?
No, the 5464-654 lacks potentiometers and does not require any calibration. You can replace it with another module without modifications.

2. What happens if the 5464-654 loses communication with the CPU?
All outputs on the 5464-654 turn off automatically. This safety feature prevents uncontrolled operation of connected equipment.

3. Does the 5464-654 provide isolated outputs?
No, the relay driver signals from the 5464-654 are not isolated. Therefore, you must use external Woodward Relay Modules for field wiring isolation.

4. What power source do the relays need with the 5464-654?
The relays require a separate 24 Vdc power source. The 5464-654 does not provide this power, so you must supply it externally.

5. How do I remove the 5464-654 from the chassis?
First, loosen the two front panel screws. Then, push the two handles outward to disengage the motherboard connectors. Finally, pull the 5464-654 out of the card guides.
