Functional Description
5462-757 is a Discrete Input Module developed by Woodward. The Discrete Input Module is linked to two separate FTMs via two low density discrete cables. The Discrete Input/Output FTM does not have LEDs, whereas the Discrete Input (with LEDs) FTM does. The FTMs provide access to all I/Os on the module, and the channels are labeled sequentially to correspond to their software locations (for example, discrete input 1 on the FTM will be discrete input 1 in the application software).
Product Attributes
- This module receives discrete signals from 48 individual switches or relay contacts and transmits them to the CPU. The MicroNet control circuitry is optically isolated from the inputs. On the 24 Vdc Discrete Input/Output FTM, the module system provides isolated +24 Vdc power for these external contacts.
- An external contact wetting power supply is required for the Discrete Input (With LEDs) FTM. There are no potentiometers for tuning and no calibration is required. Without requiring any adjustments, a module can be replaced with another 48 Ch DI Module of the same part number.
Installation
- The modules are inserted into card guides in the control's chassis and connected to the motherboard. Two screws, one at the top and one at the bottom of the front panel, hold the modules in place.
- There are also two handles at the top and bottom of the module that, when toggled (pushed outward), move the modules out just far enough for the boards to disengage the motherboard connectors.
- Each 48 Ch DI Module is connected to two 24 Vdc Discrete Input/Output FTMs or Discrete Input (With LEDs) FTMs via two low density discrete cables. The FTMs provide access to all I/Os on the module, and the channels are labeled sequentially to correspond to their software locations (for example., discrete input 1 on the FTM will be discrete input 1 in the application software). The FTM connected to J1 handles channels 1-24, while the FTM connected to J2 handles channels 25-48.
Features
- Designed to accept 24 discrete inputs. It consists of four FT Relay/Discrete Input modules, each capable of accepting six contact inputs. The module offers flexibility in terms of the power source for contact wetting voltage, which can be supplied either by the control itself or from an external source.
- For each relay module, there is 24 Vdc contact wetting voltage available. This voltage can be sourced from the control's internal 24 Vdc power source or from an external power source. The external power source can either be an 18-32 Vdc power supply or a 100-150 Vdc power supply, providing options for different system requirements.
- Since all discrete inputs are fully isolated, it is necessary to establish a common reference point between the inputs and the contact power source. When using the internal 24 Vdc power source for contact wetting, specific jumpers are required between relay module terminals 33, 34, and 35. These jumpers ensure a connection between the relay module's internal power source and the discrete input commons.
- On the other hand, if an external power source is used for contact wetting, the common of the external power source must be connected to the discrete input commons (terminals 34 and 35) of the relay module. This ensures that the reference point is established correctly, allowing proper functioning of the discrete inputs and their associated contact wetting voltage.
- Supports different options for the power source of the contact wetting voltage, be it the control's internal 24 Vdc power source or an external power source. Proper establishment of a common reference point is essential for ensuring the correct operation of the discrete inputs and their associated contact wetting voltage.

Frequently Asked Questions
What is 5462-757?
It is Discrete Input Module developed by Woodward.
How is the Discrete Input Module connected to the control system?
It is linked to two separate Field Termination Modules (FTMs) via two low-density discrete cables. The FTMs provide access to all the input/output connections on the module.
What is the difference between the Discrete Input/Output FTM and the Discrete Input FTM?
The Discrete Input/Output FTM does not have LEDs, whereas the Discrete Input (with LEDs) FTM includes LEDs for visual indication. The channels on the FTMs are labeled sequentially to correspond to their software locations, ensuring easy identification in the application software.
Is there any power supply provided for external contacts?
The 24 Vdc Discrete Input/Output FTM provides isolated +24 Vdc power for the external contacts connected to the module.
