Open collector output (H-DO-A and H-DO-C type)
The output status is an 8 points/common open collector output.
For the internal circuit driver of the H-DO module, connect the minus (
) terminal of an external
power supply (24 V DC) 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.
