Emerson A6220

Description

• Functional Features: Pulse signal acquisition and frequency conversion; real-time speed calculation; overspeed, low-speed alarm and interlock protection; digital and analog dual output.
• Performance Parameters: Measurement Accuracy: ±0.1% FS; Response Delay: ≤15 ms; Analog Output: 4 ~ 20 mA; Pulse Input Frequency: 1 Hz ~ 10 kHz.
• Material Composition: Shell: **Metal shielding casing»; Internal circuit: high-frequency counting chip, signal shaping circuit; Fixed parts: high-strength engineering plastic bracket.
• Structural Characteristics: Standard rail-type module; front panel with digital display window and indicator lights; independent input, output and power terminals.
• Working Principle: Receives pulse signal generated by speed sensor, calculates actual rotating speed through frequency conversion algorithm, compares with preset safety threshold, outputs speed data and executes protection actions when abnormal speed occurs.
• Advantages & Highlights: Wide speed measurement range; fast response; high counting precision; on-site visible digital display; reliable protection logic.
• Applicable Industries: Power generation units, industrial compressors, large fans, chemical rotating equipment, mining machinery.
• Model Series: Emerson A6000 Series Machinery Protection Modules
• Installation Requirements: Install on DIN rail in well-ventilated cabinet; sensor signal lines use shielded cables; set alarm parameters according to equipment operating requirements after installation.
• Usage Notes: Match the number of gear teeth of the speed measuring gear during parameter setting; do not access over-frequency pulse signal; regularly verify speed measurement accuracy.
