An automation unit.

摘要

A unit (U) enabling computer operation of and data acquisition from a system requiring a fluid input and supplying data in electrical form at an output. The unit comprises a valve (6) for supply of fluid between one and a plurality of selectable ports. A valve actuator (7) brings said one port and a selected port into communication in response to a signal derived from a micro-computer (1). An A/D converter (3) relays data derived from said system to said micro-computer (1) in digital form.
<??>The unit is preferably adapted for communication with an external computer (C) to permit programming of the micro-computer (1) and data acquisition by this computer (C).
