CSS CANmod.input
8 Analog, Digital, Pulse to CANBus Converter
This sensor-to-CAN module produces analog, digital and pulse measurements from 8 input channels and outputs the data via CAN bus. The module is 100% standalone, no PC required.
The compact device offers pro specs include high accuracy and high frequency sampling as well as configurable input ranges and digital thresholds.
The module integrates with any CANbus to provide data for ECUs or CAN tools. Example, you can use the module as an add-on for the CANedge.
Connect analog sensors
Sensors that produce analog outputs include force/pressure (load cells), current, distance (ultrasonic, laser, lidar, infrared), rotation (potentiometers), temperature, hall effect, magnometers, humidity, sound, atmospheric pressure, acceleration, gyroscopes - and many more.
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.

CSS CANmod.input module lets you connect up to 8 analog, digital or pulse type sensors - and output the sensor data via configurable CSS CAN frames into any CSS CAN bus 
Customers can install the CSS CANmod.input 'standalone' in any CSS CAN system (cars, trucks, ships, …) to inject configurable CSS CAN frames with input sensor data into the existing CSS CAN traffic 
Optional CSS DB25-input adapter cable enables plug & play connection of a variety of sensors via open wires for each channel (insulated via heatshrinked pin headers) 
CSS CANmod.input module can e.g. be used as a plug & play add-on for the CSS CANedge (powered via 2nd port) - letting you combine CSS CAN/LIN data with timesynced analog/digital/pulse data 
Customers can also log 2 x CSS CAN/LIN with a CSS CANedge along with data from the CSS CANmod.input, by e.g. utilizing a CSS DB9 Y-splitter to connect both devices to one of the bus networks 
CSS 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 
CSS CANmod.input can be configured via the USB connector using our online/offline config editor tool (or a simple JSON text editor) 
CSS CANmod.input measures both the analog, digital and pulse signal of every channel, enabling powerful analyses and high flexibility (picture from the asammdf GUI) 
Customers can easily mix and daisy chain multiple CSS CANmod modules, thus adding different sensor types and/or more channels
Log, Stream Sensor Data
CSS 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 realtime via USB using SavvyCAN to view raw/decoded data (e.g. via plots), ideal for validating your setup pre-deployment or for lab testing.
