Reference EN 50295:1999
Title Low-voltage switchgear and controlgear - Controller and device interface systems - Actuator Sensor interface (AS-i)
Project Number 8203
Abstract/Scope This standard specifies requirements for a bit-oriented interface system between a single controlling device and control circuit devices or switching elements as defined in EN 60947-1, connected by an unshielded, untwisted two-wire cable carrying data and power. It also enables the interchangeability of components which have such interfaces. This standard specifies: requirements for interfaces and for electromechanical structures for slaves and masters; performance of slaves, electromechanical structures and masters under normal service conditions; constructional and performance requirements; tests to verify conformance to the requirements. Specific requirements for the various profiles for slaves and masters are given in annexes A and B. NOTE 1: The standardized low-voltage switchgear and controlgear products covered by the EN 60947 series are: EN 60947-1: General rules; EN 60947-2: Circuit-breakers; EN 60947-3: Switches, disconnectors, switch-disconnectors and fuse-combination units; EN 60947-4:Contactors and motor-starters; EN 60947-5: Control-circuit devices and switching elements; EN 60947-6: Multiple function equipment; EN 60947-7: Ancillary equipment. NOTE 2: Where inputs and outputs (I/O) are described in this standard, their meaning is relative to the master. The meaning relative to the application is the opposite

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
