Monitor system

1. Overview

AN5800/80 key-phase Monitoring module receives signals from two Magneto-resistive sensors or Proximity sensors; the original signals from the sensor are converted into digital signals by a signal interface unit; the digital signals are transmitted to an embedded microcontroller unit (MCU), and are then identified, judged, processed and compared by software and output by output units, BUF port output phase (TTL level) reference signal

2. Purpose

Vibration monitoring phase reference signal

Axis eccentric monitoring phase reference signal

Throw monitoring phase reference signal

3. Function

Front BNC port buffer output

Terminal wiring buffer output

Internal bus transmitted to the function module channel requiring key-phase signal

Failure (Not ok) on-off output

LED indicator: indicating the working condition of module

4. Features

Perfect self-inspection and diagnosis function; when a failure occurs, current output is 0mA, and "Not Ok" LED on the panel is on;

Embedded microcontroller unit (MCU); an E2PROM data storage unit (for important parameters) and a FLASH process program storage unit are integrated in the chip;

Power unit: a DC-DC/AC-DC module power supply realizes ultra-width power input and isolated output;

Use forward board and back board plug-in module type structure design, after the board (power supply and relay output) and the former board (signal processing, the host) physical isolation, through case motherboard more redundant connectors (needle) in parallel connection, stable and reliable.

5. Application

6. Technical Specifications 


Magneto-resistive sensor (AN1910):

Passive, outputting TTL level signals changing with speed frequency;

Mounting clearance: 2.0mm±0.5mm.

Power supply: +12VDC /20mA;
