Woodward 5453-276 Relay Discrete Input Module

Functional Description

The Woodward 5453-276 is a F/T Relay Discrete Input Module. When installing the 24/12 TMR Discrete I/O module or the relay module within the context of the FT Relay/Discrete Input module terminal blocks, several critical electrical safety precautions must be observed. The presence of 125 Vdc on the FT Relay/Discrete Input module terminal blocks can have cascading effects, potentially resulting in the transmission of this voltage to various connected components, including the relay module sub D connectors and the cables when connected to the relay module.

Features

• Intermediary Role: Captures input signals from distinct switches or relay contacts.
• Data Transmission: Transmits input signals to the central processing unit (CPU).
• Optical Isolation: Ensures discrete signals remain electrically separate from MicroNet control circuitry, enhancing safety and reliability.
• Isolated +24 Vdc Power: Dedicated power supply for energizing external contacts associated with the 24 Vdc Discrete Input/Output Field Termination Module (FTM).
• Wetting Power Supply Requirement: Ensures proper functioning of LEDs in the Discrete Input (With LEDs) FTM and maintains optimal signal integrity.
