With the I2C input module you can read 8 digital signals up to 30V.
With the I2C input module 8 digital signals can, for example, are read by switches or sensors.
The signal states are displayed on eight low-current LEDs, the HIGH level is detected from 4V.
Changes a signal at an input will be signaled at a red LED and pulled the INT signal to LOW.
The I2C modem detects this signal change and may possibly also automatically retrieve all input cards.
Size of the circuit board 42 mm x 63 mm
