Technical Specifications:
- Signal input range: +10.0V ~ ‑24.0V, built‑in over‑voltage limiting circuit
- Input impedance: 20kΩ
- Typical power consumption: 8.0W
- Operating temperature: ‑40°C ~ +60°C
- Storage temperature: ‑40°C ~ +85°C
- Response time: Fast overspeed trigger response for safety interlock
- Supported sensors: Proximity probes, magnetic pickup tachometer sensors, compatible with 3300 series proximity transducer products Functional Features:
- Independent tachometer signal acquisition channel for rotational speed calculation
- Hardware‑accelerated overspeed judging logic, supports multi‑module redundant voting architecture
- Comprehensive self‑diagnosis for sensor fault, signal loss and module internal hardware failure
- Configurable overspeed alarm and trip threshold parameters via 3500 rack configuration software
- Fault status can be transmitted to gateway module for upper system uploading Application Scenarios: Steam turbine, gas turbine, centrifugal compressor, turbo‑expander, large‑size motor‑generator set in power plant, petrochemical and oil‑gas industry, core safety overspeed protection for high‑speed rotating machinery Performance Parameters: Speed measuring function covers low‑speed to ultra‑high‑speed rotating equipment; fault self‑check runs continuously during full operation cycle; redundant power supply must be matched in system rack for safety requirement Material Composition: Front panel: Aluminum alloy die‑casting surface anodized treatment; circuit substrate: High‑grade industrial FR‑4 printed circuit board; internal components: Industrial‑grade military‑standard chips, tantalum capacitors, high‑stability resistors; backplane connector: Gold‑plated high‑density European‑style connector for anti‑oxidation and reliable contact Structural Characteristics: Standard full‑height plug‑in card for 3500 rack front‑slot installation; front side with signal terminal connectors and status indicator LED lights; rear side adopts high‑density backplane connector for internal rack bus communication; equipped with fixed locking screws to prevent loose under equipment vibration environment Working Principle: The proximity probe or magnetic pickup generates pulse signals proportional to rotational speed. The module conditions, filters and counts input pulse signals, converts pulse frequency value to real‑time rotational speed value. The measured speed value is compared with user‑programmed overspeed setpoints. When speed exceeds threshold, internal logic outputs trip trigger instruction, and cooperates with other modules to complete voting protection action。 Installation Requirements:
- Must insert into designated slot of Bently 3500 series rack, use anti‑static wrist strap during installation
- The whole rack must configure redundant dual power supplies, this is mandatory requirement for overspeed safety system
- Torque screws shall be tightened to specified torque value to fix module firmly
- Transducer signal cables must use shielded dedicated cables, single‑point grounding for shielding layer, avoid laying together with high‑power power cables
- Complete firmware compatibility verification between module and rack backplane before power‑on Usage Precautions:
- Do not apply input signal exceeding ‑24V ~ +10V range, otherwise permanent hardware damage may occur
- All overspeed threshold parameters must be downloaded and verified by configuration software, do not modify parameters in running status without authorization
- Regularly check status LED indicator, once fault alarm light lights, carry out troubleshooting timely
- For safety protection function, module hot‑swap is not recommended under equipment running status
- Keep rack cabinet well‑ventilated, avoid dust accumulation and high‑humidity environment
