Specifications

Description

The 5462-757 is a high-density 48-Channel Discrete Input Module designed and manufactured for the Woodward MicroNet and MicroNet TMR control systems. It serves as a vital interface for capturing state changes from field devices such as limit switches, relay contacts, and pushbuttons. By translating these physical on/off signals into digital data for the system CPU, the 5462-757 enables precise sequencing, alarming, and safety monitoring of industrial prime movers.

Applications

Thermal power plants: Used in high-redundancy MicroNet TMR systems to monitor large numbers of valve limit switches and relay contacts.

Large chemical plants: Used in SIS and ESD systems for discrete signal detection, with optical isolation to block electrical noise.

Non-ferrous metal smelting plants: Installed in harsh high-temperature and high-interference environments, ensuring stable operation in demanding conditions.

Seawater desalination plants: Used in pump control systems, simplifying wiring through built-in isolated power for dry contact inputs.

Automotive assembly plants: Used for safety gate, light curtain, and interlock monitoring in large production lines with low power consumption.

Feature

High-Density Optical Isolation

The 48-channel Discrete Input Module uses 48 independent optically isolated circuits to protect the CPU and backplane from noise, ground loops, and high-voltage transients. Each channel uses only 3 mA, reducing heat and power consumption.

Flexible Contact Wetting

It supports an internal isolated +24 VDC supply or an external 18–32 VDC source. This flexibility allows compatibility with different field wiring and power systems without extra hardware.

System Integration And Termination

The module installs in the MicroNet chassis and connects through Field Termination Modules (FTMs). Each unit typically links to two 24-channel FTMs for organized signal wiring and supports hot replacement in some configurations.
