12bits (4096pts)

09.b2-Pag1

The Digital/Analog converters takes an analog signal(current or voltage)and gives a 12bits digital signal, in binary, gray or 3BCD, depending the model.

"HOLD"

Filter When the HOLD signal remains low for a time > 4.2ms, the outputwill give the average of 10 values. Useful for stable readings.

E.g. PLC 16bits input - Connect the 12 bits to the output of the Krenel converter, connecting the 12most important to the PLC and leaving the less important 4 bits connected to 0V.

For the outputs of more of 12 bits, This connection works perfectly, giving a resolution of 4.096 puntos.

< 9 10 11 B0

For the outputs of less than 2 bits, do not use the less important bits (B0, B1, B2, B3 . . . )

Can be connected different inputs to 12bits,like. 8bits . . . 16bits . . .
