DeltaV™ M-series AS-I Interface Card
DeltaV M-series AS-I interface Card
The DeltaV™ M-series actuator sensor interface (AS-i) is a field-proven interface for discrete actuators and sensors.
The interface uses an automatic addressing system via the bus connection to provide each field device a specific tag name that identifies the device for configuration and diagnostic purposes. The DeltaV system auto-senses AS-i devices and provides smooth activation of new devices. It is easy to install, reliable and simple to use.
