BMXEHC0800 8-Ch High Speed Counter Schneider Module

Product Overview

The Schneider Electric BMXEHC0800 is an 8-channel high speed counter module for the Modicon X80 automation platform. It supports counting frequencies up to 10 kHz with 5 inputs including 3 special dual-phase mode inputs for incremental encoder connection and 2 single-mode inputs for pulse counting. The module operates on 24 V DC and is compatible with push-pull incremental encoders and 2-wire/3-wire proximity sensors.

FAQ

Q: What is the difference between BMXEHC0800 and BMXEHC0200?
A: BMXEHC0800 provides 8 counter channels at 10 kHz. BMXEHC0200 provides 2 counter channels at 60 kHz for higher frequency applications.

Q: What encoder types are compatible?
A: The module accepts incremental encoders with push-pull (totem pole) outputs operating at 10 to 30 V.

Q: Is there a severe environment version?
A: Yes. BMXEHC0800H features enhanced coating for harsh environments.

Q: What terminal block is required?
A: The module requires a 20-pin removable terminal block such as BMXFTB2010 or BMXFTB2020.

Installation Guide

1. Install the module in any X80 rack slot
2. Attach a 20-pin removable terminal block
3. Connect encoder or sensor signals to the appropriate input terminals
4. Apply 24 V DC sensor power as required
5. Configure counter modes and parameters in EcoStruxure Control Expert
6. Verify count values and LED indicators during commissioning

Selection Tips

• Select BMXEHC0800 for multi-channel counting up to 10 kHz
• For 2-channel 60 kHz counting, choose BMXEHC0200
• For harsh environments, select BMXEHC0800H
• Verify encoder output type is push-pull (totem pole) compatible
• Order compatible 20-pin terminal blocks separately
