SYVECS SYV-X20L Expander X20L

Description SYVECS SYV-X20L Expander X20L

The Syvecs X20L expander controls additional I/O (inputs and outputs) in an automotive electrical installation. Using two CAN controllers, it communicates with master devices and operates as a slave, offering its entire I/O complement. All Syvecs ECUs communicate with the X20L using two wires, while incorporated logic also supports devices from other manufacturers.

Eight outputs support high-side or low-side loads and can be paired to control external DC motors for drive-by-wire and other automotive applications. Twelve low-side outputs can drive solenoids, relays, and external devices, with configurable internal pull-up and flyback diodes. Four DAC outputs convert a binary input number into an analog voltage output, such as mirroring a sensor signal to an external device.

The X20L has 12 flexible AS inputs supporting frequency detection, SENT decoding, thermistors with an internal 3k pull-up, and bipolar operation for VR sensors. The remaining eight inputs are standard 0–5 V ADC inputs. Two NTK lambda sensor circuits allow sensors to connect directly and output the oxygen ratio via CAN to the master device.
