AEM Electronics 22-Channel CAN Sensor Modules 30-2212

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
