Functional Description

5437-283 is an analog FTM developed by Woodward. It comes in low and high voltage models, each with specific voltage ranges and power requirements, providing flexibility and reliability in control and automation systems. It is available in low voltage models that operate on 20 to 40 Vdc and high voltage models that work with either 88 to 132 Vac or 90 to 150 Vdc. Both variants necessitate a minimum power capacity of 15 W to function effectively.

Actuator Current Ranges

• This FTM offers models tailored to three different actuator current ranges. Additionally, there is a high-voltage model, compatible with both 90 to 150 Vdc and 88 to 132 Vac power sources, and a low-voltage model designed for 20 to 40 Vdc.
• The high voltage model is distinguishable on the front panel, allowing for easy identification.

Reverse-Acting Systems and Actuator Control

• In reverse-acting systems, the actuator responds by increasing fuel flow when the actuator voltage decreases. Moreover, in cases of complete voltage loss to the actuator, it will automatically move to the full fuel position.
• This design ensures that a backup mechanical ballhead governor can assume control, preventing the prime mover from shutting down, as typically seen in direct-acting systems.

Optional Deceleration Ramp

• An optional deceleration ramp feature is available with this FTM. When enabled, it takes approximately 20 seconds to transition from rated speed to idle speed, enhancing control precision.

Precautions for PCB Removal

• In instances where you need to remove the PCB (Printed Circuit Board) from the control cabinet, it's crucial to exercise caution. Avoid touching any part of the PCB except its edges. Steer clear of the electrical conductors, connectors, or components, using only non-conductive devices. When replacing a PCB, keep it inside the provided plastic antistatic protective bag until installation.
• Immediately place the old PCB in the same protective bag after removal from the control cabinet.
• These precautions are essential to prevent damage and ensure the PCB's integrity during handling and replacement.

Frequently Asked Questions

What is 5437-283?
It is a Field Terminal Module developed by Woodward.

What types of connections do FTMs provide for field wiring?
FTMs provide cage-clamp terminal connection points for field wiring. These terminals are designed to securely hold and connect wires, ensuring reliable electrical connections.

What additional functions do module offer?
FTMs also provide shield termination and EMI (Electromagnetic Interference) protection. Shielding helps protect the system from external interference, which is particularly important in industrial environments where electrical noise can be a concern.

How are FTMs mounted?
It can be conveniently mounted on 35 mm DIN Rails, simplifying the installation process. This eliminates the need for interposing terminal blocks, streamlining field wiring connections.

What wire sizes are compatible with the cage-clamp terminals?
The cage-clamp terminals and relay modules can accept a maximum of one #12 AWG (American Wire Gauge) wire or two 18 AWG wires. This flexibility accommodates a range of wire sizes commonly used in industrial applications.

How is field wiring hookup performed?
Field wiring hookup is straightforward with FTMs. It involves stripping the wire back approximately 0.312 inches (8 mm), inserting it into the cage clamp terminal, and then tightening the screw. This process ensures a secure and dependable connection.
