  2. Multi‑sensor compatible input‑channels, single monitor‑unit simultaneously processes vibration, shaft‑displacement, rotational‑speed and multi‑point temperature‑monitoring signals.
  3. Independent Alert and Danger alarm‑threshold setting for each measurement‑variable; supports complex multi‑condition combined‑alarm‑voting‑logic configuration for machinery‑protection‑requirements.
  4. Four‑channel isolated 4‑20 mA recorder‑output transmits processed measurement‑values to external DCS and PLC control‑systems.
  5. Six programmable relay‑contact‑outputs realize alarm‑annunciation and light‑duty machinery‑trip‑protection‑logic.
  6. Dedicated buffered transducer‑output for each dynamic‑channel, convenient for on‑site signal‑verification and portable‑diagnosis‑instrument‑connection.
  7. Built‑in 200‑entry timestamped‑event‑log records alarm trigger‑time, fault‑status and sensor‑loop‑fault‑events, supports post‑fault‑trace‑analysis.
  8. Comprehensive sensor‑loop fault‑detection function, identifies probe open‑circuit, short‑circuit and sensor‑loop abnormal‑condition, outputs Not‑OK fault‑status.
  9. Supports optional remote‑mount display‑keypad‑module, remote‑display module can install separately up to 75‑meters away from main monitor‑unit.
  10. Rich communication‑options including Modbus TCP Ethernet and serial‑port interfaces, directly connect with upper‑level System‑1 condition‑monitoring‑software and plant control‑systems.
  11. Full‑parameter‑configuration via dedicated 1900‑series configuration‑software, no hardware‑jumper‑adjustment required on monitor‑body.
  12. Front‑panel LED indicator array shows channel health‑status, alarm‑state and module‑fault‑information for fast on‑site‑troubleshooting. Application Scenarios: Condition‑monitoring and light‑duty protection for packaged compressors, blowers, large‑fans, process‑pumps and reciprocating‑machinery; OEM skid‑mount equipment supporting; medium‑size unit reconstruction‑project without large‑rack TSI‑hardware; industrial‑site local‑alarm‑monitoring‑points; predictive‑maintenance data‑acquisition‑nodes needing Ethernet‑Modbus communication‑access. Performance Parameters: Measurement accuracy ±1% full‑scale; fast alarm‑response speed; strong industrial‑electromagnetic‑interference‑resistance; high MTBF value for long‑term continuous‑operation. Material Composition: Reinforced metal‑alloy monitor housing; upgraded multi‑layer mixed‑signal PCB‑board; 24‑bit high‑resolution ADC chips; enhanced‑performance digital‑signal‑processing microprocessor; multi‑group electromagnetic‑isolation components; relay‑contact assemblies; screw‑type terminal‑block assemblies; LED status‑indicator components; Ethernet‑communication circuit components. Structural Characteristics: Rectangular metal‑enclosure for panel‑mount or 19‑inch rack‑mount installation; front‑panel LED‑status‑indicator array; rear‑side multi‑group terminal‑blocks for sensor‑input, power‑supply, relay‑output and communication‑wiring; dedicated interface‑port for remote‑display‑keypad‑module connection; housing printed with model‑number, electrical‑rating and unique serial‑identifier. Working Principle: Analog‑signals from field‑installed sensors enter monitor‑unit through input‑terminal‑blocks. On‑board circuit completes signal‑conditioning, filtering and high‑speed 24‑bit analog‑to‑digital conversion. Upgraded internal micro‑processor executes configured multi‑variable measurement‑algorithms, calculates vibration‑amplitude, shaft‑displacement, rotational‑speed and temperature‑measurement‑values. Calculated measurement‑values compare with preset Alert and Danger alarm‑threshold and combined‑voting‑logic‑conditions. When threshold‑exceeding or sensor‑loop‑fault‑event happens, corresponding relay‑output executes action and event‑log records timestamped‑event‑information. Processed measurement‑data converts to 4‑20 mA analog‑output for external control‑system‑input. Measurement‑data, fault‑status and event‑information transmit to upper‑host‑system through serial‑port or Modbus TCP Ethernet‑communication‑interface. Installation Requirements:
  13. Install monitor‑unit onto standard 19‑inch rack or cabinet front‑panel according to dimension‑specification, fasten mounting‑screws fully.
  14. Strictly distinguish power‑supply terminals, sensor‑input terminals, relay‑output terminals, communication‑port and remote‑display‑interface terminals; complete wiring complying with official wiring‑diagram.
  15. Supply regulated 24 VDC power‑supply within allowable voltage‑range for monitor‑unit.
  16. If remote‑display‑keypad‑module is deployed, use specified communication‑cable and control installation‑distance within maximum 75‑meter limit.
  17. Separate sensor‑signal‑cable routing‑path away from high‑current power‑cables to reduce electromagnetic‑interference‑coupling.
  18. Complete channel‑function‑definition, measuring‑range‑setting, alarm‑threshold and combined‑logic‑configuration work by 1900‑series configuration‑software, download all parameters into monitor‑internal‑memory before commissioning.
  19. Check front‑panel LED‑indication status after power‑on, eliminate sensor‑loop Not‑OK‑fault before putting into formal operation. Usage Notes:
  20. Do not exceed maximum contact‑load rating of relay‑output‑terminals; adopt external intermediate‑relay for heavy‑load‑driving‑application.
  21. Do not open monitor‑housing; internal components do not support field‑repair, replace complete monitor‑unit upon hardware‑failure.
  22. Maintain sufficient ventilation‑clearance around monitor‑housing, do not block heat‑dissipation‑area.
  23. Check terminal‑block screw‑tightness during each equipment‑overhaul‑cycle to avoid signal‑abnormality caused by loose‑contact.
  24. Regularly export timestamped‑event‑log‑data for equipment‑fault‑trend‑analysis‑work.
