Open collector output (DO-A type)
The output status is an 8 points/common open collector output.
For the internal circuit driver of the DO module, connect the minus (-) terminal of an external power
supply to the number 6 terminal and connect the positive (+) terminal of the power supply to the
common line of each output.
In using the open collector output, an external power supply of 24 V DC is required.
Note that if this power supply is not connected, there will be no output from the module.
