AS-i Bus System for Series 79 Actuator

The AS-i Bus system for pneumatic actuators is a module for adapting the series 79 pneumatic actuator for use with the AS-i bus networking protocol. AS-i bus is a low-cost solution for managing complex automation environments and are capable of covering long distances. The AS-i bus system uses stainless steel M12 connections for quick installation and mounts directly to the actuator to create a small package size.
