Connecting the I/O (RTU-810/DAx types only)
Binary inputs:
The binary inputs are divided into two groups per port. Each group contains 4 inputs
with one common terminal. The inputs are bipolar, so they can be switched with an
active "+" or active "-" signal.
If the "C" terminal is connected to the ground, the inputs will be active if the positive
voltage (12-14V) applies. If the "C" terminal is connected to the positive voltage, the
inputs are activated by applying the ground connection.
Please note that the input voltage should not exceed 24V +20%!
Binary outputs:
The supply voltage for the binary outputs must be connected to the "+" and "-" terminal
of port C. Active outputs will have the positive supply switched to the related terminal.
The maximum load is 0.5A per outputs.
