1. General Product Overview

2. Application Scope

This modular monitor realizes integrated multi-parameter real-time measurement and emergency trip protection for steam turbines, centrifugal compressors, large induced draft fans, heavy feed pumps and industrial screw blowers. Per fixed code 24 channel definition, onboard universal input ports support software-only mode switching without hardware replacement: receiving negative DC output signal from matched proximitor-probe assemblies for non-contact radial shaft vibration and axial thrust displacement measurement; processing casing vibration signals from velocity or acceleration transducers to monitor absolute housing vibration; accessing pulse signals from magnetic keyphasor pickups to track real-time rotor rotating speed and overspeed status; independent dedicated temperature channels collect bearing bush temperature, motor winding temperature and equipment shell temperature via industrial standard PT100, K, J, T, E-type thermocouples with embedded cold junction compensation circuit to eliminate ambient temperature measuring drift error. After internal high-precision signal conditioning, 24-bit ADC digital sampling and comparison with user-programmable Alert and Danger threshold values, the unit outputs multiple forms of signals: passive C-type dry contact relays drive local sound-light alarm components and equipment emergency shutdown interlock loops; galvanically isolated 4-20mA linear analog outputs transmit measured physical values to DCS distributed control system and local field panel indicators; the integrated Modbus-RTU communication specified by code 24 enables centralized digital transmission of real-time measured data, alarm records and historical fault information to upper computer monitoring platform for long-term equipment trend analysis and predictive maintenance management, meanwhile front panel digital display allows field maintenance staff to directly read on-site operational parameters without extra configuration tool connection.

3. Detailed Electrical Performance Specifications

3.1 Variable Power Supply Definition for XX Code Segment

The XX variable coding position is reserved for flexible factory preset power configuration, covering three mainstream industrial power options: wide-range 18~32VDC industrial DC power, fixed 24VDC standard DC power and 85~264VAC universal alternating current specification to match diversified cabinet power distribution environment on different industrial sites. All power variants integrate built-in multi-layer protection circuits including reverse polarity prevention, instantaneous surge suppression, overvoltage and short-circuit auto-cutoff protection to avoid internal component damage caused by on-site miswiring or sudden power grid fluctuation. Optimized low-power circuit layout controls full-load total power consumption below 9.2W to limit continuous heat generation, enabling stable long-time running inside compact sealed control cabinet without additional external cooling fan or auxiliary heat dissipation accessory.

3.2 Fixed Input Channel Configuration under Code 24

Code 24 corresponds to factory fixed channel allocation combining multi-group universal dynamic signal input ports and independent temperature measurement ports. Every dynamic input channel is pre-calibrated at factory with default 7.87V/mm sensitivity for standard AISI4140 steel target to perfectly match Bently mainstream proximity transducer series, users freely adjust measurement range, scale factor and monitoring mode via official dedicated configuration software without any hardware modification. All temperature input terminals equip automatic cold junction compensation module to offset terminal ambient temperature fluctuation interference and guarantee temperature testing precision within ±0.5℃ under variable cabinet environmental conditions; internal high-resolution analog-to-digital conversion design effectively restrains measurement error interference induced by surrounding high-voltage cabinets and variable frequency drive equipment in complicated electromagnetic field industrial environment. Spare buffered raw signal output terminals are reserved on terminal layout for regular field debugging and periodic instrument calibration work.

3.3 Output & Communication Functional Parameters

Multiple groups of independent passive dry contact relay outputs are configured for equipment normal status indication, Alert warning, Danger protection and channel circuit fault feedback separately, each relay contact bears maximum rated load capacity of 250VAC/5A to directly access on-site safety interlock circuits without intermediate isolation relay equipment. Multi-channel galvanically isolated 4-20mA analog outputs provide proportional linear signal corresponding to real-time measured physical value for remote centralized data collection of DCS system and local field instrumentation. Following code 24 configuration, onboard hardware integrates standard RS485 bus interface supporting Modbus-RTU multi-drop networking communication protocol, allowing multiple monitors to be connected on single communication bus to realize centralized data uploading for whole workshop equipment monitoring network construction.

3.4 Built-in Continuous Automatic Self-Diagnosis System

Background diagnostic program keeps running during full equipment operation cycle to monitor wiring integrity of all connected sensors, extension cables and internal core circuits. Once probe open-circuit, cable short-circuit, proximitor power failure or measured clearance out of calibrated linear range occurs, corresponding front panel fault indicator LED will light up and designated fault relay synchronously changes contact state; all abnormal fault codes, failure occurrence time and channel information are automatically stored into nonvolatile onboard memory supporting over 200 pieces of event data storage for later maintenance troubleshooting and failure root-cause analysis.
