High precision analog and digital testing board
Complete ECU testing, especially hardware in the loop testing, requires not only connecting the communication network to the testing system, but also connecting digital and analog signal interfaces. The high-precision analog and digital testing boards developed by Fengchuan Power can greatly simplify the setup of testing benches and HIL testing systems, and improve the efficiency of system construction and testing. The analog board supports stable output of positive and negative voltages ranging from -12V to+12V, while the digital board supports output of the ABZ three channel correlated signal of the analog magnetic encoder.
Analog testing board (main parameters)
Power supply: Supports a supply voltage of 9V to 32V, with a supply current greater than 2A.
Input channels: 8 input channels, capable of measuring voltage and current simultaneously. The voltage measurement range is -25V to+25V, and the current measurement range is -25mA to+25mA, with a measurement error of ± 1% for both.
Output channels: 8 output channels, capable of controlling output voltage and current without the need for manual switching of output modes. The output voltage range is -12V to+12V, and the current output range is -25mA to+25mA, with an output error of ± 2% for both.
RS485 communication: Control output voltage, output mode, and read input voltage and current through the RS485 interface. Supports one question one answer mode and power-off memory function.
CAN communication: Control and read board parameters through FDCAN or CAN2.0B, such as output voltage, output current, output mode, and read input voltage, input current, etc. Support power-off memory function.
Digital quantity testing board (main parameters)
Power supply: Supply voltage of 6V to 32V and supply current greater than 1A. The input channel accepts voltages ranging from 3.3V to 12V, while the output channel can be powered by an internal 5V isolated power supply or an external 7V to 25V power supply.
Input channels: 8 input channels, capable of measuring signal period, positive pulse width, and negative pulse width. Supports a maximum period of 429 million microseconds and a minimum pulse width measurement of 10 microseconds, with a measurement accuracy of ± 5 microseconds.
Output channels: 8 output channels, supporting two independent ABZ encoded signal outputs and two independent PWM outputs. The output channel can output PWM signals up to 1MHz and encoded signals up to 600KHz.
RS485 communication: Control and read board parameters through RS485, such as input capture channel, capture data, output encoded signal frequency and phase, etc. Supports one question one answer mode and power-off memory function.
CAN communication: Control and read board parameters through FDCAN or CAN2.0B, such as input capture channel, capture data, output encoded signal frequency and phase, etc. Support power-off memory function.
