Connect digital sensors

Sensors with digital outputs include hall effect switches, buttons (for e.g. registering events), reed switches (e.g. for door/valve/latch position registration), resistance-to-digital (RTD) sensors and more. Many sensors with analog outputs also produce optional digital outputs.

Connect pulse sensors (frequency, counter)

Sensors with pulse-oriented outputs include rotational speed sensors (e.g. hall effect frequency sensors), rotational position sensors, buttons & toggle switches (event counters), frequency meters and sensors producing e.g. Pulse Width Modulation (PWM) outputs.

 

Easily add analog/digital/pulse data to any CAN bus system

Add analog/digital/pulse data via 8 input channels to your CAN bus - e.g. for use by ECUs or CAN hardware.

• Powerful parallel sampling of analog/digital/pulse signals
• Configure input range for optimal resolution/amplification
• Configure digital high/low levels incl. optional hysteresis
• Dedicated excitation signal for powering input sensors (~3.3 V)
• Quickly connect sensors via optional DB25-input adapter cable
• Replace excitation signal with e.g. 12V/24V via DB25-DB25/DB9
• Optionally output signals via CAN FD for fewer frames
• Daisy-chain multiple modules for 16, 24, 32, ... channels
• Power device at 5-26 V DC via standard DB9 adapter cables
• Optionally record the data via any CAN interface/logger/...
• DBC file included for easy decoding to human-readable form

You can easily mix and daisy chain multiple CANmod modules, thus adding different sensor types and/or more channels

You can install the CANmod.input 'standalone' in any CAN system (cars, trucks, ships, ...) to inject configurable CAN frames with input sensor data into the existing CAN traffic

The optional DB25-input adapter cable enables plug & play connection of a variety of sensors via open wires for each channel (insulated via heatshrinked pin headers)

The CANmod.input module can e.g. be used as a plug & play add-on for the CANedge (powered via 2nd port) - letting you combine CAN/LIN data with timesynced analog/digital/pulse data

You can also log 2 x CAN/LIN with a CANedge along with data from the CANmod.input, by e.g. utilizing a DB9 Y-splitter to connect both devices to one of the bus networks

The CANmod.input offers vast functionality and pro specs - yet it is extremely compact, measuring only 7 x 2 x 5 CM and weighing just 70 G

The CANmod.input can be configured via the USB connector using our online/offline config editor tool (or a simple JSON text editor)

The CANmod.input measures both the analog, digital and pulse signal of every channel, enabling powerful analyses and high flexibility (picture from the asammdf GUI)

Example: Log/stream sensor data

The CANmod.input is often used as an 'add-on' for the CANedge. This setup lets you record e.g. vehicle data via Channel 1 and analog/digital/pulse data via Channel 2. The data can be easily DBC decoded via e.g. the asammdf GUI, Python or MATLAB.

You can also stream the sensor data in real-time via USB using SavvyCAN to view raw/decoded data (e.g. via plots) - ideal for validating your setup pre-deployment or for lab testing.

Use Cases

The CANmod.input can be installed standalone in any CAN bus system - including e.g. as an add-on for the CANedge.

 

Add analog/digital/pulse signals to your CAN bus

Need to inject sensor data directly into your CAN bus?

The input-to-CAN module can be used standalone to inject CAN frames with analog/digital/pulse sensor measurements into e.g. your vehicle/machine CAN bus system. The data can be consumed by other CAN nodes on the network - e.g. ECUs, cabin displays, CAN loggers or telematics control units (TCU). To ensure compatibility, you can modify the module output bit rate and CAN IDs via the simple GUI config editor. The module is ideal for e.g. prototype vehicle testing, automotive/industrial development and more.

 

CAN + sensor data logging & telematics

On-road vehicle telematics

Need to collect vehicle and analog input data via 3G/4G?

The CANedge3 can upload data while on-the-road via 3G/4G using your own SIM card. You can use a DB9-Y-splitter to power the CANmod.input voltage recorder via the 2nd port of the CANedge3. The uploaded log files can e.g. be visualized in telematics dashboards. Ideal for e.g. 'sensor telematics' use cases like predictive maintenance, remote diagnostics and more. You can of course also daisy chain other CANmod modules like the CANmod.temp temperature-to-CAN module.

 

Daisy-chaining input modules

Need a larger number of sensor input channels?

The CANmod.input is extremely simple to setup and configure. With easily customizable CAN frame IDs you can quickly daisy-chain several modules to add 8, 16, 24, ... analog/digital/pulse inputs to your CAN bus (e.g. using DB9-Y-splitters). Every individual input channel can be independently configured - allowing for complete customization. If you wish to record the data to a CAN bus data logger, you can use the CANedge to easily power a full chain of modules via the 2nd port.
