The Sink Output module requires two power sources. The DC 24V power source is used to drive the internal FET.
The Sink Output Module has a wider output voltage range than the Source Output Module. DC Output Modules can output a pulse of up to 1KHz meaning it can be switched on and off at about 1000 times per second.
The MOACON Digital I/O Modules come in 2 flavors: the Source Output Module, and the Sink Output Module.
General Digital I/O (DIO) modules can be installed in the 6 slots directly to the right of the CPU module in the slots labeled “DIO”. The slot in which the DIO module is installed determines its I/O port number.
When a general DIO module is installed in position “+0” its ports will be assigned numbers 0 through 7. When installed in position “+30” its ports will be assigned numbers 30 through 37.
