AEM 22-channel CAN sensor modules provide a way for users with carbureted vehicles to add an AEM CD digital dash display. They also let users with existing CAN-based devices add more channels to the display for viewing and/or data logging. These 22-channel modules convert analog, digital, and frequency inputs into an AEMnet CAN bus signal that can be transmitted to AEM's CD-5 carbon and CD-7 digital dashes.
AEM Electronics 22-channel CAN sensor module includes:
- Wiring harness with 36 in. flying leads and pre-wired CAN cable
- IP65-rated enclosure is dust-tight and water-resistant
- Daisy-chain two modules together for additional channels (modules sold individually)
- Four dedicated 0-5 V analog inputs
- Four temperature (thermistor) inputs
- Four user-configurable inputs for 0-5 V, temp (including RTD)
- One dedicated fuel level input (0 to 250 ohm range)
- Six digital inputs, active low, protected to about 18 V, frequency, duty cycle or simple switch
- One tach input, trigger when low, 12 V internal pull up
- Two VR pair frequency inputs (crank, wheel, or driveshaft speeds)
- Jumper selectable CAN bus speeds, 250k, 500k, 1M
- Jumper selectable terminating resistor
- Jumper selectable header length, 11 bit or 29 bit
