CAN UIO16 open collector input
I have CAN-UIO16 device. There are sensors that have open collector output. In other words sensor output can be float or grounded. CAN-UIO16 device input detects float or CANx device power supply (+24 V).
A question does it is possible to detect open collector based signals on CANx inputs.
You need an external pull-up resistor (around 10kohms) between +24V and the input. Most open drain outputs are rated up to 30V but check the device that you want to connect.
