METRIX TXR Series Technical Notes

The Evolution of TXR Architecture

The TXR series originated as a rack-mounted analog signal conditioning platform targeting turbomachinery OEM integrators. Early-generation modules (TXR-1000 through TXR-9000 range) relied on discrete analog circuitry with hardwired trip setpoints, requiring physical jumper configuration for each channel. As plant automation migrated toward digital fieldbus topologies in the late 1990s and early 2000s, METRIX introduced firmware-configurable variants with HART and Modbus RTU overlays, enabling remote setpoint adjustment without module extraction.

The mid-generation TXR-20000 and TXR-30000 series introduced dual-channel architectures, SIL 2-rated trip logic, and expanded transducer compatibility covering eddy-current proximity probes, velocity sensors, and accelerometers. The TXR-33505 belongs to this mature mid-to-late generation, offering a consolidated I/O footprint with integrated relay outputs and diagnostic LED arrays. Compatibility across backplane generations requires verification of rack revision levels; TXR-33505 is confirmed compatible with METRIX 5500 and 5900 series racks but requires an adapter bracket for legacy 4000-series enclosures.
