    Chinese RoHS labels, a lower case "e" within a circle with arrows, can also imply compliance. The WEEE directive logo. RoHS 2 attempts to address this issue by requiring the aforementioned CE mark whose use is policed by the Trading Standards enforcement agency. [32] It states that the only permitted indication of RoHS compliance is the CE mark ...

    Today, microprocessor-based relays can perform many protective functions in one device. [1] When one device performs several protective functions, it is typically denoted "11" by the standard as a "Multifunction Device", but ANSI Device Numbers are still used in documentation like single-line diagrams or schematics to indicate which specific ...

    The DTOC relay has been used extensively in the United Kingdom but its inherent issue of operating slower for faults closer to the source led to the development of the IDMT relay. [1]: pp 30-31 A definite time over-current (DTOC) relay is a relay that operates after a definite period of time once the current exceeds the pickup value. Hence ...

  8. Solid-state relay - Wikipedia

    en.wikipedia.org/wiki/Solid-state_relay

    A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.

  9. Numerical relay - Wikipedia

    en.wikipedia.org/wiki/Numerical_relay

    Digital/numerical relays provide a front panel display, or display on a terminal through a communication interface. This is used to display relay settings and real-time current/voltage values, etc. More complex digital relays will have metering and communication protocol ports, allowing the relay to become an element in a SCADA system.
