Introduction

Eight full bridges provide mV/V input on 8 independent channels.

Communication interfaces such as USB port, EtherCAT, RS232 or CANbus are available.

Does not support RS-485.

The device has 8 configurable analog outputs (±10 V and 4-20 mA among others). UART

interface serves to control the measuring amplifier via the Raspberry PI (not for versions

with EtherCat).

There are three common types of the BX8.

oAS, HD15 and HD44. Each have their own Input/Output connectors.

8-channel measuring amplifier

8x input configurable

Interfaces

Communication interfaces such as USB port or EtherCAT or CANbus are available. The

device has 8 configurable analog outputs (±10 V and 4-20 mA among others). UART interface

serves to control the measuring amplifier via the Raspberry PI (not for versions with EtherCat).

The interface protocol of USB and UART is identical and described in a separate

documentation. The fieldbus protocols EtherCAT and CANopen are standardized in the lower

protocol layers and the application layer is described in separate documents.

Software

The Windows programs BlueDAQ multichannel with graphical user interface and the console

terminal program BlueDAQ are suitable. A Windows function library (MEGSV8w32.dll) with

commented C header is available for self-programming users and a LabVIEW library with

wrapper VIs for this DLL for programming with LabVIEW ©.

Features

There are 8 analog inputs available. They are individually configurable as:

–Strain gauge input for full bridges in 4 and 6 wire technology or

–Strain gauge input for half bridges or

–Strain gauge input for quarter bridges 120 ohm, 350 ohm, 1 kOhm or

–Single-ended input ±10 V or

–Input for PT1000 temperature sensor

The strain gauge supply voltage can be switched between 8.75 V, 5.00 V and 2.5 V, assigned

to input sensitivities 2 mV/V, 3.5 mV/V or 7 mV/V.
