General Information About the BMXETM0200H Module

Definition

The module BMXETM0200H is an expert module for speed and frequency control.

It provides two independent channels for fast speed measuring up to 500 kHz.

Each channel supports:

One input to interface sensors such as:
- Magnetic pickup (MPU) in variable reluctance technology
- Active pickup (APU) including electronic for signal conditioning
- Incremental encoders
One reflex output controlled from an embedded compare function.

Platform Compatibility

This module is compatible with the following platforms:

M340 PLCs
M580 PLCs including Hot Standby configurations.

In M580 Ethernet remote I/O configurations, the module can only be installed in a drop that includes an X80 or eX80 performance EIO adapter module (BM•CRA31210).

Typical Application

The module functionalities enable speed measuring for governor control of turbo-machinery such as hydro-power or gas turbine.

The speed value (also called frequency value) is published each 10 ms to the PLC task. This enables fast regulation loops.

Thanks to a pattern recognition feature, the module provides a fast and accurate measurement for asymmetrical machine rotation patterns, such as slow speed reciprocating engines.
