Xycom 602939-01 XVME-203/293 Counter Module 70203-00

Xycom 602939-01 XVME-203/293 Counter Module 70203-00

Overview

The XVME-203 is a single-high, VMEbus-compatible board, using two AM9513A timer/counter de

vices to provide a total of ten 16-bit counting channels. 

The timer/counter devices are fully program mable and capable of counting at a rate of up to 5 MHz. 

In conjunction with the timer/counter devices,the XVME-203 employs an AM9519A Universal

Interrupt Controller to provide a complete interrupt structure via eight interrupt channels. 

This interrupt structure allows for the selection of either a fixed interrupt vector for all eight channels or a separate vector for each individual channel.

The XVME-203 can also be used for a quadrature detection.  

Advanced encoding circuitry allows the module to be used with as many as four quadrature transducers simultaneously.

Eight output channels (ten on the XVME-293) are available to provide a variety of utility functions

including: frequency output, one-shot output, fre quency division, and pulse generation.

Product Overview

Xycom 602939-01 XVME-203/293 Counter Module 70203-00 is a powerful counter module launched by Xycom, belonging to the XVME series products. This module is mainly used for precise counting and measurement of pulse signals, playing an important role in industrial automation, testing and measurement, motion control and other fields. By counting, measuring frequency, and measuring period of input pulse signals, accurate counting and timing information is provided to the system, helping to achieve precise control and monitoring functions.

Specification parameters

Input channels: Typically equipped with multiple independent counting input channels, there may be 4-8 high-speed counting channels, each of which can independently count and measure input pulse signals to meet multitasking processing requirements.

Counting range: With a wide counting range, it can achieve 32-bit or 64 bit unsigned counting, with a maximum counting range of 4294967295 (32-bit) or 1844674407909551615 (64 bit), ensuring accurate counting in various application scenarios.

Input signal type: It supports multiple input signal types, including TTL level signal, differential signal, etc., and can adapt to output signals of different sensors and equipment, with good compatibility. The frequency range of the input signal can generally reach several tens of kHz to several MHz, for example, it can support high-speed pulse input signals up to 5MHz, meeting the needs of high-speed counting and measurement.

Output function: Some models may have output functions, such as pulse output, comparison output, etc. The output signal can be used to trigger other devices or as a control signal to achieve collaborative work with external devices. The type and parameters of the output signal can be configured according to actual needs.

Communication interface: It may be equipped with standard communication interfaces such as RS-232, RS-485, Ethernet interfaces, etc., to facilitate data exchange and communication with other devices or control systems. Through the communication interface, the status and data of the counter can be read in real time, and the counter can also be remotely configured and controlled.

Working power supply: Powered by a DC power supply, the common working voltage range is+5V DC ± 5%,+12V DC ± 5%, or+24V DC ± 5%, depending on the product model. The power input has overvoltage and undervoltage protection functions to ensure that the module works properly in unstable power environments.

Working temperature range: capable of stable operation in harsh industrial environments, with a general working temperature range of -40 ℃ to+85 ℃ and a storage temperature range of -55 ℃ to+125 ℃, suitable for environmental conditions in different regions and industrial sites.

Core functions

Counting function: It is the core function of this module, which can accurately count the input pulse signals. Supports multiple counting modes, such as add count, subtract count, add/subtract count, reversible count, etc., and can be flexibly selected according to actual application needs. It can record the number of pulses in real-time and store the counting results in an internal register for the system to read and process.

Frequency measurement: It can accurately measure the frequency of the input pulse signal by counting the pulses within a certain period of time and calculating the frequency value of the signal based on the time interval. High measurement accuracy, able to meet the requirements of high-precision frequency measurement, widely used in fields such as motor speed measurement and vibration frequency monitoring.

Cycle measurement: In addition to frequency measurement, it can also measure the cycle of input pulse signals. By recording the time interval between adjacent pulses, the period of the signal can be calculated, providing important data for analyzing the characteristics of the signal.
