BMX EHC 0200/0800 counter modules
Presentation
BMX EHC 0200 and BMX EHC 0800 counter modules for the Modicon M340
automation platform are used to count the pulses generated by a sensor or to process
the signals from an incremental encoder.
The two modules differ in their number of counter channels, maximum input frequencies,
functions and auxiliary input and output interfaces:

2 –
The sensors used on each channel can be:
2-wire 24 V proximity sensors
3-wire 24 V proximity sensors
10/30 V output signal incremental encoders with push-pull outputs
BMX EHC 0200/0800 counter modules can be used to meet the demands of
applications such as:
Alarm generation on empty unwinder status using the ratio
Sorting small parts using the period meter
Single electronic cam using the dynamic setting thresholds
Speed control using the period meter
These standard format modules can be installed in any available slot of a Modicon
M340 PLC. They are hot-swappable.
In a Modicon M340 PLC configuration, the number of BMX EHC 0200/0800 counter
modules should be added to the number of application-specific modules
(communication).
The function parameters are set by configuration using the Unity Pro software.
Description
BMX EHC 0200/0800 counter modules are standard format. They occupy a single
slot in BMX XBP ppp racks. They come in a plastic case, which ensures IP 20
protection of the electronics, and are locked into position by a captive screw.
BMX EHC 0200 module, 2 channels, 60 KHz
The front panel of the BMX EHC 0200 counter module features:
Module and channel status display block
16-way connector for connecting the sensors of counter 0
16-way connector for connecting the sensors of counter 1
10-way connector for connecting:
Auxiliary outputs
Sensor power supplies
To be ordered separately:
A BMX XTS HSC 20 kit containing two 16-pin connectors and one 10-pin
connector
A BMX XSP pp00 shielding connection kit if the rack is not already equipped with
one (see page 1/11).
BMX EHC 0800 module, 8 channels, 10 KHz
The front panel of the BMX EHC 0800 counter module features:
Module and channel status display block
Connector taking the
3 BMX FTB 20p0 20-way removable terminal block (same
as that of I/O modules)
To be ordered separately:
A 20-way removable terminal block
3 (cage clamp, screw clamp or spring-type)
BMX FTB 20p0
A BMX XSP pp00 shielding connection kit if the rack is not already equipped with
one (see page 1/11).
