TBUX297247

The TBUX297247 is a 32-point discrete digital input expansion module from Schneider Electric, designed for use with SCADAPack Smart RTU systems. Sold under the model designation 5405-24, this module extends the I/O capability of compatible SCADAPack controllers by adding 32 optically isolated DC inputs rated for 12–24V operation. It is an essential building block for industrial SCADA and telemetry installations that require reliable, high-density discrete signal acquisition.TBUX297247

This module organizes its 32 inputs into four isolated groups of eight, with each group sharing a single common return. That group isolation design reduces interference between field circuits and simplifies troubleshooting in complex wiring environments. LED indicators on the faceplate show the real-time status of each input point, and the module supports DIN rail mounting with removable connectors that allow replacement without disturbing field wiring. It is compatible with a wide range of SCADAPack 300 series and 32-series RTU controllers.TBUX297247

This unit is offered in used and fully tested condition, providing a cost-effective path to sourcing a module that has been discontinued by the manufacturer. Each unit undergoes functional verification prior to shipment, helping to ensure it meets the performance expectations of the original design. Buyers replacing failed or aging components in existing SCADAPack installations will find this a practical and budget-conscious alternative to new or retrofit solutions.

As a purpose-built industrial I/O module, the 5405-24 was engineered for demanding process environments. Its optical isolation architecture protects the logic bus from field-side voltage transients, and the removable terminal connectors minimize downtime during maintenance or module swaps. Whether you are maintaining a pipeline monitoring network, water treatment facility, or remote telemetry site, this expansion module delivers the dependable discrete input capacity that SCADAPack-based systems rely on.TBUX297247

32 Discrete Inputs: This module provides 32 optically isolated digital input points rated for 12–24V DC operation, expanding the I/O capacity of SCADAPack RTU systems.
Optical Isolation: All digital inputs are optically isolated from the logic power supply, protecting the controller bus from field-side electrical disturbances.
Grouped Wiring: Inputs are organized in four isolated groups of eight, each sharing a common return, which simplifies field wiring and reduces cross-circuit interference.
LED Status Indicators: Individual LED indicators on the module face display the live on/off status of each of the 32 input channels for easy monitoring and diagnostics.
Removable Connectors: The field wiring connectors are removable, allowing the module to be swapped out during maintenance without disturbing or re-terminating existing field wiring.
