The A7 I/O Device 4/4 is a general-purpose digital input
and output device that can be used to control external
devices, such as a torch cleaning station. It is capable of
driving +24 V logic signals, relays, and valves, and reading
logic states, switches, and digital sensors. Inputs are read
and outputs written by a robot.
The A7 I/O Device 4/4 has 4 inputs and 4 outputs by default.
It can be extended by A7 I/O Extension Card 8/8 that is
available separately. The extension card has additional 4
inputs and 4 outputs, resulting in the total of 8 inputs and
8 outputs when equipped.
