The AS-i valve top module contains an AS-i slave as well as two digital inputs and two digital outputs.
The supply of the pcb and all peripherals is carried out via AS-Interface.
The module has been designed especially for the use in valve tops.
Two inductive sensors detect the open/closed position and one or two solenoid valves are used for pneumatic triggering.
The printed conductors are coated with a protecting lacquer against corrosion.
The integrated watchdog ensures that the solenoids are switched off in case of a bus communication failure.
Pack quantity 1 pcs.
