What is BS EN 50325-1 ‒ Controller-device interfaces about?
BS EN 50325-1 is the first part of an international multi-series standard that covers industrial communications subsystem for controller-device interfaces.
BS EN 50325-1 applies to controller-device interfaces that provide, defined interfaces between low-voltage switchgear, control gear, control circuit devices, switching elements, and controlling devices.
BS EN 50325-1 specifies requirements for controllers and devices utilizing these interfaces, including not only the communication protocol specification, but also associated relevant electrical and mechanical characteristics.
BS EN 50325-1 establishes a consistent terminology and format for the subsequent interfaces. It also harmonizes requirements of a general nature, in order to reduce the need for testing to different standards, increase understanding and facilitate comparisons of controller-device interface standards.
Note: The controller-device interface standards currently part of this series are:
EN 50325-4: CANopen
EN 50325-5: Functional safety communication based on EN 50325-4
