Description:

With the I2C input module, 8 digital signals, e.g. Of switches or sensors.

The signal states are indicated on 8 low-current LEDs, the HIGH level is detected between 2.5 and 30 V depending on the used resistor network.

If a signal is changed at an input, this is indicated by a red LED and the INT signal is pulled to LOW.

The I2C modem recognizes this signal change and can also automatically query all input cards.

Dimension of the circuit board 42 mm x 63 mm

Resistors:

The input voltage range of the card can be adapted using the resistance network RBV.
