MXB modules
The SomatXR MXB modules are front end data sourcing modules that can be used as expansion modules with the SomatXR/eDAQXR data processor. They are configurable to interface to a diverse range of transducers and sensors. Generic features for most MX modules include precision measurement capabilities using 24 bit ADCs, TEDS sensor support and multiple digital filtering options. All MXB modules have a similar back panel with a power connector, two FireWire connectors and one Ethernet connector.
MXB modules can be connected to an EXRCPU/EXRLCPU layer directly or through one or more EX23-R Ethernet switches. For more information on setting up a system with MXB modules, see Connecting MXB modules to an EXRCPU/EXRLCPU.
The data processor is designed to use Ethernet based PTPv2 protocol (IEEE1588) for time and data synchronization with MX modules and other peripherals. FireWire connections between MX modules are available and useful to simplify power distribution. When FireWire connections are used, timing and data synchronization between MX modules may or may not be based on the FireWire protocol.
CAUTION
All MXB modules in the system must have an Ethernet connection (either directly to the data processor or indirectly through an EX23-R). Connecting an MXB module to any other MXB module using FireWire without both having an Ethernet connection to the data processor can result in acquired data not being synchronized to the data processor on one or more MXB modules.
Decimal sample rates and Linear Phase FIR and Butterworth FIR digital filters that match the sample rates and digital filters in the eDAQ are available. However, the MXB modules do not phase align the Linear Phase FIR filters as the eDAQ does (i.e., the phase delay of the MXB Linear Phase FIR filters is dependent on the sample rate and digital filter characteristics). In addition, a comprehensive set of Butterworth IIR and Bessel IIR digital filters are available for use with the Decimal sample rates. The data processor also supports the traditional (Classic) HBM sample rates and IIR digital filters.
All SomatXR MXB modules can also be combined with MXB modules of the QuantumX (MXB...) and QuantumX-P (MX...-P) series and can be connected to the CX22 W data recorder and the CX27 Ethernet and EtherCAT gateway. For more information on using MXB modules in a standalone system with the catmanAP and MX Assistant software applications, refer to the MX Modules User Manual.
Available QuantumX modules
For more information about a QuantumX module, download the current manual from www.hbm.com/daq-support. The following non-ruggedized modules are currently supported in the CX23-R/EXRCPU/EXRLCPU interface:
- MX1601B Standard Module (Universal Amplifier): Up to 16 configurable inputs for DC voltage sources (60 V, 10 V, 100 mV), DC current sources (20 mA) or current-fed piezoelectric transducers (IEPE, ICP®). This module is functionally equivalent to the MX1601B-R in laboratory environments.
- MX1609KB Thermocouple Amplifier: Up to 16 type K thermocouples (NiCrNi) for measuring temperatures. This module is functionally equivalent to the MX1601B-R in laboratory environments.
- MX1615B Bridge Module (Strain Gage Amplifier): Up to 16 individually configurable inputs, including strain gage-based transducers, standardized voltage and resistance or resistance-based measurements. This module is functionally equivalent to the MX1601B-R in laboratory environments with the following exceptions – 15V input mode instead of 60V input mode, one positive swing (upscale polarity) shunt resistor only, shunt scaling is not supported.
- MX471B CAN Module: The module has 4 CAN bus nodes that can be configured for receiving messages.
- MX878B Analog Output Module: Up to 8 analog output channels with +/-10V range that can be sourced from any MX module channel that is connected via FireWire. CX23-R/eDAQXR support is limited to an input follower mode where each analog output channel follows the defined input data source using the following scaling. The user defined Range max parameter value for the source MX channel maps to +10V analog output voltage; the user defined Range min parameter value maps to -10V analog output voltage. The nominal data skew between the analog output and the source input to the associated MX module channel is nominally 3 milliseconds when no digital filters are used.
- MX840B Universal Module: Up to eight (8) universal inputs for connecting more than 16 transducer technologies. This module is functionally equivalent to the MX840B-R in laboratory environments with the following exception – one positive swing (upscale polarity) shunt resistor only.
- MX460B Frequency / Counter Module: Up to four (4) digital inputs to measure digital pulses up to 1 MHz (speed, torque, angle position, displacement, PWM in general). This module is functionally equivalent to the MX460B-R in laboratory environments. CX23-R/eDAQXR support is limited in the following aspects. Math functions are not supported. Interactive zeroing of the “crank shaft” sensors is not supported.
