Technical Specifications Input Signal Type: Eddy current probe analog signal, accelerometer signal Terminal Form: Screw clamping terminals Built-in Filter: Low-pass signal filter Operating Temperature: -40℃ ~ +70℃ Storage Temperature: -50℃ ~ +85℃ Mounting Type: DIN rail mount Relative Humidity: 5%~95%, non-condensing
Functional Features Receives weak analog signals from rotating machinery field sensors. Built-in low-pass filter to suppress high-frequency electromagnetic noise. Overvoltage protection to limit abnormal voltage entering rack system. Centralized terminals simplify on-site wiring and troubleshooting. Compact structure to save cabinet installation space. Clear channel marking for rapid maintenance.
Application Scenarios Signal input terminal for Bently 3500 machinery protection system. Shaft vibration and axial displacement sensor signal wiring. Steam turbine, gas turbine and centrifugal compressor monitoring cabinet. Power generator set condition monitoring system. Oil and chemical plant rotating equipment online monitoring.
Structural Characteristics Flame retardant plastic casing with DIN rail buckle. Front panel printed with channel serial numbers. Internal PCB integrated filter and protection components. Screw terminals arranged in order for convenient wiring operation. Locking clip to fix module firmly on DIN rail.
Working Principle Weak analog signals from field sensors enter the module through screw terminals. High-frequency interference noise is filtered out by the low-pass filter circuit. The overvoltage protection circuit limits abnormal surge voltage. Processed clean signals are delivered to rack monitoring modules through matched connecting cables for subsequent measurement and alarm judgment.
Installation Requirements Install the module on standard DIN rail in control cabinet. Separate sensor signal cables from high-power and high-voltage cables. Use shielded twisted pair cables for field sensor connection. Tighten terminal screws to ensure reliable electrical contact. Ground the shielding layer according to Bently official grounding specification. Check signal integrity after wiring completion.
