AEG AS-884A-201 High-Speed Counter Module
- Product Introduction: It is a high-performance high-speed counter module of the AEG Modicon 884 series, specially designed for collecting high-frequency pulse signals from industrial field speed sensors, encoders and proximity switches. It can realize high-precision counting, frequency measurement and position detection, and transmit the collected data to the PLC CPU in real time to provide data support for the speed, position and displacement control of the equipment.
- Technical Specifications:
- Counting Channels: 4 independent high-speed counting channels, supporting single-phase and two-phase (A/B phase) pulse input.
- Counting Frequency: Single-phase pulse maximum 500 kHz, two-phase A/B pulse maximum 250 kHz (4X quadrature decoding).
- Counting Range: 32-bit signed integer, range from -2147483648 to 2147483647.
Detailed content
-
- Input Signal Type: Differential TTL level (5 VDC) and open collector NPN/PNP level (24 VDC), configurable per channel.
- Trigger Function: Supports hardware trigger (start/stop/reset) and software trigger, with trigger response time ≤1 μs.
- Communication Interface: Connected to the Modicon 884 series backplane bus, data transmission rate up to 10 Mbps.
- Power Supply: 24 VDC, power consumption of 5 W.
- Isolation: 2500 VAC isolation between channels and between channels and the backplane bus; Operating Temperature: -25°C to +70°C; Protection Rating: IP20; Dimensions: 140mm × 160mm × 55mm (W×H×D).
- Functional Features:
- Supports multiple counting modes: up counting, down counting, up/down bidirectional counting and cycle counting, which can be flexibly set according to application requirements.
- Each channel is equipped with independent preset value and comparison function, which can trigger alarm or control signal output when the counting value reaches the preset value, realizing real-time closed-loop control.
- Built-in pulse signal filtering function, the filtering frequency can be set from 100 Hz to 100 kHz, effectively suppressing the interference pulse in the industrial field and ensuring the accuracy of counting.
- Has high-speed data capture function, which can capture the instantaneous pulse value and time stamp, and is suitable for the detection of fast-changing motion parameters of equipment.
- Supports online parameter modification and real-time counting value monitoring, without shutting down the system to adjust the counting mode and preset value, which is convenient for on-site debugging and operation.
- Equipped with multi-channel LED indicators, displaying the counting status, pulse input status and fault status of each channel in real time, which is convenient for visual troubleshooting.
- Application Scenarios: Widely used in industrial equipment that requires high-precision speed and position control, such as CNC machine tool feed axis position detection, packaging machinery bag length counting and speed regulation, textile machinery yarn length counting, elevator speed and position monitoring, and automated assembly line conveyor belt speed control. It is also applied in the field of industrial measurement, such as the counting of product flow and the detection of mechanical part displacement.
