Datasheet Summary
Bi-directional Remote Sensor Unit Interface Features and Benefits
Two identical interface channels for remote sensor units Two connection modes: connection to OUTx and RETx or connection to OUTx and GND pin 16 bit Standard SPI for control and diagnosis via a microcontroller Supply voltage for each remote unit with a supply current up to 45mA Current limitation with an analog feed back loop for each channel Receive data from the remote unit by current modulation with a transmission rate of 10kHz Transmission of data to the remote unit via PWM voltage pulses Data input/output can be directly connected to a microcontroller input/output (CMOS) Low current consumption All pins to the...
