Actuator Sensor Interface (AS-Interface or ASi) is an industrial networking solution (Physical Layer, Data access Method and Protocol) used in PLC, DCS and PC-based automation systems. It is designed for connecting simple field I/O devices (e.g. binary ON/OFF devices such as actuators, sensors, rotary encoders, analog inputs and outputs, push ...

ASi makes it simple. Equipping Moniteur VPTs with an ASi interface card adapts your on/off automated valves to an advanced ASi valve network. Money and time are saved as installation and maintenance are streamlined with reduced wiring and improved system diagnostics.

As-i valve, inductive sensor, and temperature sensor options. The AS-i AirBox is a combination of an I/O module and a solenoid valve. In pneumatic applications, it is used for decentralised …

devices such as process valves are connected over the AS-i cable and the AS-i master to the controllers at the field level. AS-Interface provides the option of transferring standard data and safety-oriented data on the same cable. This allows, for example, the emergency stop cabling of a machine or system to be implemented over AS-i.

The ASi protocol is a simple interface system for connecting sensors and actuators with only two wires. It has very high-speed communication, very reliable, and has high levels of noise immunity to make it useful for a large variety of field device connections.

The Alfa Laval ThinkTop® AS-Interface is a modular control unit that offers reliable, cost-effective operation and standard functionality for automated sensing and control of hygienic valves. The ThinkTop AS-Interface provides real-time information about valve operating status 24/7 while boosting productivity and securing traceability.

2016年2月17日 · As-I (Actuator Sensor-Interface bus) is a digital communication link that powers up and transmits on/off signals between an AS-I master and AS-I sensors or actuators (for example your valves). Newer profiles have been added in recent versions that support some analog signalling and Safety Integrated.

Moniteur's VPCs with encapsulated ASi interface cards adapt your on/off automated valves to an advanced 2-wire ASi valve network. Money and time will be saved as installation and maintenance are streamlined with reduced wiring and improved system diagnostics.

The Axiom’s pneumatic valve system consists of a low-power pilot that drives the main high- flow spool valve. Pilots may be selected for conventional or bus networking applications.
