Designed with high-voltage\/low-voltage (HV\/LV) power input capabilities and voted relay outputs, the \u003cstrong\u003e8237-1600\u003c\/strong\u003e provides critical monitoring and trip execution functions for industrial rotating machinery such as turbines and turbo-expanders. The unit features speed settings configurable up to 80,000 rpm (with maximum speed frequency handling up to 32 kHz), a low-pass filter on acceleration signals, sudden speed loss detection, and integrated front-panel display and key navigation. Interface capabilities include consecutive Modbus address mapping and analog\/register reads.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePanel-mount enclosure design with HV\/LV power input configuration and voted trip relay outputs\u003c\/li\u003e\n\u003cli\u003eConfigurable speed settings from 32,000 rpm up to 80,000 rpm facilitating turbo-expander applications\u003c\/li\u003e\n\u003cli\u003eMaximum input speed frequency up to 32 kHz\u003c\/li\u003e\n\u003cli\u003eConfigurable low-pass filter on acceleration signals and customizable speed loss failure thresholds\u003c\/li\u003e\n\u003cli\u003eFront panel interface featuring speed display with configurable filtering, one-decimal precision below 100 rpm, and fast key response\u003c\/li\u003e\n\u003cli\u003eFront panel Trip and Alarm buttons for toggling between Log and Latch screens\u003c\/li\u003e\n\u003cli\u003eDedicated front panel display screens for Shared Reset, Shared Start, and Shared Speed Fail Override\u003c\/li\u003e\n\u003cli\u003eAuto Sequence Test functionality displaying comprehensive sequence test results\u003c\/li\u003e\n\u003cli\u003eConsecutive Modbus register mapping with scaled analog reads for speed and acceleration values\u003c\/li\u003e\n\u003cli\u003eCompatible with ProTech Service Tool (9927-1810 Rev.
