TBUX297378

The TBUX297378 is a compact 16-point discrete digital input expansion module from Schneider Electric, operating on 12/24V AC/DC signals and designed for use with SCADAPack 300 series, 300E series, and 32 series remote terminal units. Built around the SCADAPack Model 5414-24 platform, it gives engineers a reliable and cost-effective way to extend their field I/O capabilities without replacing existing controller hardware. Whether monitoring valve positions, motor states, or level switches, this module integrates seamlessly into established SCADA and telemetry architectures.

Each of the 16 inputs on this unit is optically isolated, protecting the controller backplane from field-side voltage spikes and electrical noise—a critical requirement in oil and gas, water treatment, and utility infrastructure applications. Status LEDs on every input channel provide real-time visual feedback during commissioning and troubleshooting, reducing diagnostic time in the field. Configuration is handled through SCADAPack RemoteConnect software, keeping the setup process consistent with the rest of the SCADAPack ecosystem.TBUX297378

This listing is for a used and fully tested unit. Each module goes through functional verification before shipping, giving buyers confidence that what they receive is ready for installation. Sourcing a pre-owned expansion module is a practical choice for system expansions, spare inventory, or replacement of failed hardware—especially for installations running legacy SCADAPack controllers where new production units may carry long lead times.TBUX297378

With its compact form factor, universal AC/DC input capability, and broad controller compatibility, this module remains a workhorse in industrial automation and remote monitoring applications worldwide. Buyers maintaining SCADAPack-based infrastructure will find this a dependable, fully interchangeable drop-in solution for their existing systems.
