Digital inputs of the Monarco HAT are designed to work in 24V, 12V or 5V logic.
- Logic low voltage (FALSE, OFF) of digital inputs on the Monarco HAT is:
−30 V to 1.8 V
- Logic high voltage (TRUE, ON) of digital inputs on the Monarco HAT is:
3.5 V to 30 V
Please note that the digital inputs are optically isolated and they share a common negative potential. The voltage is measured against DIN COM−. To emphasize this fact, the Monarco HAT connector is shipped with a jumper cable between DIN COM− and GND.
