Introduction to 1771-VHSC-B E02 Counter Module

1771-VHSC-B E02 is a High Speed Counter Module in the Allen Bradley (AB) 1771 series, used for high-speed counting and processing of pulse signals in industrial automation systems. This module is often used in conjunction with PLC for position control, speed monitoring, or event counting.

Main functions
1. High speed counting

Support multi-channel pulse input for high-speed counting

Suitable for encoder, rotary switch or sensor signals

Can achieve pulse accumulation, direction counting, and incremental counting

2. Signal processing

Built in filtering and signal shaping functions to improve pulse recognition accuracy

Supports multiple input types such as TTL/HTL, NPN/PNP, etc

Can be used for counting range setting, preset values, and reset control

3. Communication with PLC

Module data can be directly transmitted to the 1771 series PLC

Used for closed-loop control, position monitoring, and automated logic operations

Support interrupt triggering or periodic scanning to read count values

4. Industrial grade reliability

The module design meets the requirements of industrial environment and has strong anti-interference ability

Built in fault detection and alarm interface to improve system reliability

Typical Applications

Pulse counting of CNC machine spindle or feed axis

Position detection of automated conveyor lines

Rotating machinery, packaging equipment, and conveyor belt counting

Joint position feedback of industrial robots

High speed counting and control of sensor or encoder pulse signals
