2. Extension board
IM041 input and conversion control module is mainly applied to intelligent building automation field.
It converts four-way on-off outputs to a group resistance output, and get function extension cooperating
with specified thermistor input port (NTC,10K ) of DDC controllor.The extension helps to reduce
hardware cost for building automation system.
