With the I2C analog input card 5 analog signals of 0-10 V can be read.
The minimum purchase order quantity for the product is 1
New product
The analog-in card has a total of 5 A / D converter with a resolution of 10 bit. The analog-in card is completely controlled register. All data is stored in readable and writable registers.
Controls all operations on the map by a microcontroller (PIC 18F13K22). This establishes the connection between the I2C bus and the A / D converters. It ensures that the data is updated in the registers with a frequency of 80 Hz ..
The minimum value of a register is 0 × 0000 (dec. 0) the Maximum 0x03FF (dec. 1023). The A / D converter to measure against an internal reference voltage of 2.048 volts. Therefore corresponds to the maximum value of a measurable voltage of 2.048 volts at the input. With appropriate input resistors can be the measuring area of the map to expand.
Size of the circuit board 42 mm x 63 mm
