The Syvecs X20L expander is a very powerful device for controlling additional I/O (Inputs and Outputs) in an automotive electrical installation. With the use of two CAN controllers, the X20L communicates with master devices to behave as a slave for it, offering the entire I/O compliment to its master device. All our ECU’s (engine control units) will communicate with the X20L with just the use of 2 wires and we have also incorporated logic to allow other manufactures to be able to work with the X20L as well.
8 of the outputs on the X20L are designed to be driven to a high load or low load, making them extremely flexible in what they can offer. These h-bridge outputs can be paired to control external DC motors which are used in drive by wire applications or many other automotive applications.
12 low-side outputs which drive the outputs to ground are also useful for driving solenoids, relays and external devices. These outputs also have the ability to have internal pull-up and fly-back diodes set.
4 DAC (digital-to-analog) outputs are also present on the that convert a binary input number into an analog voltage output. These outputs are useful for sending out a voltage to external device to mirror a sensor signal for example.
While the X20L has 20 inputs not all of them share the same capabilities. 12 of the inputs (AS Inputs) are fully flexible and support frequency detection, SENT decoding, Thermistor (internal 3k pull up) and bipolar operation which means the voltage is monitored above and below the reference ground for use with VR Sensors. The remaining 8 inputs are standard 0-5v ADC inputs.
To finish off the serious I/O compliment that the X20L offers, are 2 x NTK Lambda sensor circuits which allow a sensor to be connected directly and output the oxygen ratio via CAN to the master device.
