Open collector output (H-DO-D type)
The output type becomes the transistor sink load output of 16 channels/2 commons (output type: 2
8
points/common).
In order to drive the output circuit within the H-DO module, connect a minus line (
) of the external
power supply (24 V DC) to the number 9 pin on the DO1 to DO8 side, and a plus line (+) of the same
power supply to the number 10 pin and the common line of each point from DO1 to DO8.
In addition, connect a minus line (
) of the external power supply (24 V DC) to the number 19 pin on
the DO9 to DO16 side, and a plus line (+) of the same power supply to the number 19 pin and the
common line of each point from DO9 to DO16.
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.
