Expansion Modules

Using the CAN network at 1Mbsec any number of expansion modules may be added to a data logging system to increase the number of possible channel inputs.

Input modules are available to cover almost any motorsport sensor input type, such as:
• 0-5v single ended
• +/- 5v bi polar
• Strain gauges
• Thermocouple
• Temperature – NTC / PTC / PT1000
• LVDT
• Digital for wheel speed and RPM

 

GPS Module - The VB10SPS is a non-contact speed and position sensor based on 10Hz GPS technology. Data output is via CAN Bus to allow easy integration into most motor sport and testing applications.

The VB10SPS also features analogue and digital outputs. The analogue output corresponds to either vehicle speed or lateral acceleration with user selectable scaling while the digital output can be configured as either a digital speed pulse output or a lap beacon marker.

Ideally suited to marine applications

MPC2C CAN to CAN interface - This user programmable CAN interface has been designed to link multiple different CAN systems to a common high speed CAN network within the logger network. Each MPC2C device is manufacturer programmed to suit the CAN speeds of all common vehicle networks.

All loggers utilise the CAN2-A format with a standardized internal structure to enable simple connection to all of our own system modules and devices. For this reason, nearly all external CAN streams (regardless of speed) are fed through an MPC2C device before entering the logger.

We understand that the format and structure of your CAN systems may be highly sensitive and rarely allowed beyond the walls of your organization. For this reason we give you the tools necessary to create and test the interface, all we provide is the hardware and software to make it happen.

MP16-D 16 input high speed expansion module - The MP16D CAN expansion module has been designed to function as a high acquisition rate, multi purpose channel input module.

16 individual bi-polar inputs with adjustable gain from 1,10 or 100 may be used for the majority of sensor types, as well as temperature compensation for thermocouple inputs. All are programmable via RS232 using a dedicated software tool Three versions are available, the only difference being the CAN transmission rate of 200Hz, 500Hz, 1kHz.

This device may be used with any of the following sensor output types – 0-5V single ended or bi-polar / variable resistance / Thermocouple type K grounded or ungrounded.

MP16-J Input Junction box for the MP16D - The MP16-J junction box has been specifically designed to ’mate’ directly with the MP16-D CAN expansion module, giving access to each of the 16 inputs as individual connections.

This junction box proves invaluable when using the MP16-D in an environment where testing requirements are changeable. Users are given full access to the signal distribution PCB where a range of hardware ‘jumpers’ are available to easily change the input configuration.

The housing is a machined aluminium enclosure with individual connections for each input as well as 2 lemo connections for CAN, and a single RS232 connector for programming the MP16-D module.

The small internal void coupled with free flowing ventilation between the MP16D and the distribution PCB ensure minimal error for remote TCK compensation, although it is recommended that thermocouples are directly wired to the MP16D to avoid any cold junction error.

DKM16A 16 input expansion module - The DKM016A CAN expansion module has been designed to function as a high-resolution generic input expansion module with 16 individual single ended inputs that may be used with the majority of sensor types.

Housing is a horizontally designed machined and anodised aluminium enclosure sealed to IP67 using an Autosport series 37-way connector.  3 x M4 tapped holes are provided for easy mounting.

FM16-A 16 input 4kHz expansion module - The FM16A is a high speed CAN expansion module able to acquire up to 16 inputs at 12bit resolution. The user has the choice to log either 16inputs at 1Khz, 8 inputs at 2Khz, or 4 at 4Khz. Filtering and gain are programmable via software.

Multiple modules may be used within the same system providing the modules are fitted to separate CAN lines, this is done to avoid data throughput overload on the CAN lines.

DKM04IC digital input expansion module - The DKM04IC expansion module may be used as a general-purpose digital input module for use with Hall Effect or inductive sensors**, or as a wheel speed module using the on-board features.

In addition to the 4 separate inputs, associated with inputs 1 & 2 are individual distance counters, a calculated speed channel taken and a re-calculated distance taken from this derived speed channel. Using the Table Manager set-up application the user is able to calibrate the inputs for differing wheel circumference & triggers per revolution.

DKM04A analogue input expansion module The DKM04A expansion module may be used where lower resolution 10-bit measurements of 0-5V inputs are acceptable. Each module is hardware configured to transmit the 4 inputs using a pre-defined set of CAN addresses (Maps) in Word format.

Customised versions of this module are available to provide alternative reference voltages and input ranges. A single Vref voltage supply and analogue ground are common to all inputs.

Housing is a machined aluminium enclosure with individual connections for each input as well as 2 separate ports for CAN-in and CAN-out.

DKM02TK 2 input thermocouple expansion module - The DKM02TK expansion module is pre-calibrated for direct connection to any type K thermocouple. All signal linearisation and the cold junction compensation are carried out within the module.

In standard format, up to 8 thermocouples may be connected to any individual CAN line using the 4 CAN maps that are available. For users who require a far greater number of thermocouple inputs it may be preferable to utilise one of the programmable 16 input modules MP16D

Housing is a machined aluminium enclosure with individual connections for each input as well as a single port for CAN. The CAN junction should be carried out within the wiring assembly.

DKM02TK 2 input strain gauge expansion module - The DKM02D module has been specifically created to enable direct connection to a full bridge strain gauge via a 4 way Lemo connector.

An internal offset of 0.5V (against the 2.5v supply) provides an 80% / 20% shift in the zero value to give greater measurement range in one direction, a feature of most automotive measurements. Alternative voltage offsets are available on request.

Other features of the DKM02D include a reference 2.5V sensor supply and a fixed gain of 500, which may be changed at the time of ordering. Gauge trim for zero and calibration can be carried out within the logger configuration software – Table Manager
