CSS Electronics -CANmod.input: 8 x Analog/Digital/Pulse to CAN Bus Converter

This sensor-to-CAN module produces analog, digital & 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 incl. high accuracy and high-frequency sampling - as well as configurable input ranges and digital thresholds.

The module integrates with any CAN bus to provide data for ECUs or CAN tools. For example, you can use the module as an add-on for the CANedge.

Connect analog sensors

Sensors that produce analog outputs include force/pressure (strain-gauge), 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.

 

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, load cell analysis, automotive development and more.

CAN + sensor data logging & telematics

Need to collect vehicle CAN bus and sensor data via SD/WiFi?

The CANmod.input can be deployed as an 'add-on' module for the CANedge. Simply configure the CANedge to provide a 5V power out via the 2nd port - and connect the CANmod.input via the optional adapter cable. This lets you log e.g. vehicle CAN bus data via channel 1 and time-synced analog/digital/pulse data via channel 2. Data can be offloaded periodically when the asset is within WiFi range - e.g. via a warehouse or garage WiFi router.

On-road vehicle telematics

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

The CANedge2 can upload data while on-the-road using e.g. a 3G/4G USB router. You can power the 3G/4G hotspot from the vehicle - or use our DB9-DB9/USB adapter to power both the hotspot and CANmod.input voltage recorder via the 2nd port of the CANedge2. 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 temperature-to-CAN and GPS-to-CAN modules.

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.
