Technical Specifications Power is supplied through 3500 rack back‑plane bus, nominal power consumption 3WBaker Hugh…. Total 16 independent measurement channels, compatible with platinum, nickel, copper RTD and multiple types of isolated‑tip thermocouples. Operating ambient temperature ‑40℃ ~ +70℃, relative humidity 5%‑95% non‑condensing. Standard plug‑in card structure for 3500 series rack, IP20 protection grade. Front‑panel integrated wiring terminals without external termination block required. Back‑plane high‑speed internal system bus communication. Multi‑group LED indicators for module operation, channel alarm and fault status. Support TMR triple modular redundant voting configuration.
Functional Features Realize multi‑channel temperature signal acquisition for RTD and isolated‑tip thermocouple. Built‑in cold‑junction compensation for thermocouple input. User‑programmable alert and danger alarm thresholds for each channel.
Application Scenarios Steam turbine bearing temperature monitoring, gas turbine component temperature supervision, centrifugal compressor thrust and radial bearing temperature measurement, large generator stator winding temperature detection, petrochemical process equipment temperature protection, thermal power plant turbomachinery safety monitoring cabinet.
Structural Characteristics Standard plug‑in circuit card matched for 3500 rack chassis. Front‑panel equipped with integrated signal wiring terminals and multi‑status LED indicator lamps. Gold‑plated back‑plane contact pins guarantee stable bus signal transmission under vibration environment.
Working Principle RTD or thermocouple temperature signals access module front‑end circuit through built‑in terminals. Internal hardware completes signal conditioning, cold‑junction compensation and analog‑to‑digital conversion. The measured temperature value is compared with pre‑configured alarm threshold.
Installation Requirements Insert module into designated slot position of Bently 3500 series rack. Ensure back‑plane gold‑plated contacts are clean, undamaged and fully engaged. Confirm rack main power supply operates normally. Guarantee cabinet internal ventilation and heat‑dissipation performance. Keep installation area away from high‑voltage cable bundles and strong electromagnetic interference sources. Fasten front‑panel anti‑looseness locking buckle after insertion.
