EFR - Radio Ripple Control Receiver

• The relays that control the connected devices can often be provided in plug-in format, so that a radio ripple control receiver with three to six relays can be assembled, depending on the design and construction. 
• The long-wave signal antenna is usually built into the equipment, but it also has an interface for connection of additional remote antenna.

• Two protocols are in general use for addressing radio ripple control receivers: Versacom and Semagyr. Independent of protocol, all radio ripple control receivers have an internal memory in which the switching programme for the device is stored. The receiver operates autonomously and is synchronised via long-wave radio; and the same route is used for receiving changes to the programme.
• The Versacom protocol uses a four-level hierarchy of address groups, which allows rapid structuring of a radio ripple control programme. Receiver firmware for Versacom devices has been specially developed to meet the requirements of feed-in management.
• Semagyr permits very flexible addressing by means of a free division of address “bit lists”. Switching programmes using Semagyr protocol are generally rather more complex, but offer a wider range of possibilities.
• Choice of which protocol to use, and the selection of the associated long-wave receivers, depends on what ripple control technology is already in use, and the intended range of tasks.
• We will be happy to advise you about matters relating to addressing systems and protocols.

• Construction: Mast-mounted, top-hat rail mounted, three-point mounted
• Relays: Up to 6 (plug-in)
• Protocols: Versacom, Semagyr
• Antenna: Mostly internal, with interface for external antenna

Field of Application

• Synchronised tariff switching of electricity meters
