Inputs

Each analog input can be jumper-configured in 1 of 4 ways:

²        0-5V signal

²        0-10V

²        0-20mA

²        Dry contact, thermistor, open-collector. thermistor default is 10K NTC, but can custom according to your sensor type

All digital inputs can be jumper-configured in 1 of 2 ways:

²        Wet contact input

²        Dry contact, open-collector input
