Description

Allen-Bradley 1738-VHSC24M23 Ultra-High Speed ​​Counter Module

Product Dimensions：

The Allen-Bradley 1738-VHSC24M23 is a high-performance, dual-channel Very High-Speed Counter (VHSC) module belonging to the ArmorPoint I/O family. Designed for harsh environments, it provides distributed control capabilities without the need for a separate protective enclosure.

## Product Overview

The 1738-VHSC24M23 is an “On-Machine” I/O solution that features an IP67/IP69K rating. It is specifically designed to process high-speed pulse signals from encoders, proximity switches, and other pulse-train devices.

### Technical Specifications

## Key Advantages

• On-Machine Mounting: Its rugged design allows you to mount the module directly on the equipment, significantly reducing wiring costs and cabinet space requirements.

• Precision Timing: With a 1 MHz counting frequency, it handles high-speed applications that standard I/O modules simply cannot track.

• Durability: Built to withstand high-pressure washdowns and extreme vibration, making it ideal for food/beverage and heavy industrial sectors.

• Versatile Operation: Supports multiple modes including Counter, Encoder, and Period/Rate measurement.

## Important Considerations & Safety

Warning: To prevent damage or injury, ensure that the power is disconnected before connecting or disconnecting the M23 cables.

1. Shielding: Use shielded cables for high-speed pulse inputs to minimize electromagnetic interference (EMI), which can lead to false counts.

2. Mounting Orientation: While the module is rugged, it should be mounted to allow for proper drainage during washdown cycles.

3. Current Limits: Ensure that the 24V DC power supply is sized correctly to handle the module’s consumption and the connected sensors.

4. Pin Configuration: Carefully verify the M23 connector pinout against your encoder’s wiring diagram, as incorrect wiring can damage the input circuitry.

## Product Applications

The 1738-VHSC24M23 is typically used in scenarios where rapid movement and precise positioning are critical:

• Packaging Lines: Tracking conveyor belt speeds and coordinating product spacing.

• Material Handling: Determining the exact position of automated guided vehicles (AGVs) or lift systems using rotary encoders.

• High-Speed Sorting: Identifying and diverting items on a line based on pulse-count distance.

• Cut-to-Length Applications: Measuring precise lengths of material (metal, fabric, or paper) for automated shearing.
