Schneider BMXEHC0800 High-Speed Counter Module

Schneider Modicon X80 8-Channel Counter BMXEHC0800

Product Introduction

The BMXEHC0800 belongs to the Schneider Electric Modicon X80 family. This module provides eight independent high-speed counting channels in a single slot. Industrial engineers use it for position feedback, flow measurement, and motion monitoring. Because the unit fits both M340 and M580 racks, it simplifies spare-part planning across mixed control systems.

Technical Specifications

First, the BMXEHC0800 offers eight counting channels with channel-to-channel isolation. Each channel accepts incremental encoder signals and reaches a maximum frequency of 10 kHz. This range suits moderate-speed applications such as conveyor tracking and shaft rotation monitoring. Furthermore, a module status LED gives technicians fast visual diagnostics during commissioning.

The counting mode supports incremental encoders. Therefore, the module converts pulse trains into digital counts for the CPU. Meanwhile, isolation between channels reduces cross-talk in dense cabinets. For instance, one noisy axis will not disturb neighboring channels. In addition, the compact width of 28 mm saves valuable DIN rail space.

Electrical Parameters

The BMXEHC0800 draws power from the backplane at 24 V DC. Its consumption is 3.6 W, while bus current sits at 150 mA at 24 V DC. Besides, the backplane supply removes the need for extra field wiring to the module. However, engineers must confirm the rack power budget before installation. Specifically, add the bus current of every module to avoid overload.

Mechanical and Environmental Data

Dimensions measure 100 × 28 × 93 mm (H×W×D), and the unit weighs only 0.17 kg. The protection rating is IP20, so the module belongs inside a clean control cabinet. Operating temperature ranges from 0°C to +60°C. Storage temperature spans -25°C to +70°C. Relative humidity stays between 5% and 95%, non-condensing. Moreover, the single-slot design keeps the rack layout tidy. Finally, the shared I/O platform supports both M340 and M580 controllers.

Installation Guide

Next, follow these steps to mount the BMXEHC0800 correctly.

1. Switch off rack power and confirm zero voltage.

2. Align the module with the free slot and slide it into the backplane connector.

3. Tighten the retaining screw to secure the unit.

4. Wire encoder signals to the front terminals according to the pin diagram.

5. Power the rack and check the module status LED.

6. Configure the counter parameters in the engineering software.

Additionally, keep signal cables away from motor power lines. This practice lowers electrical noise. Therefore, counting accuracy improves in harsh environments.
