Schneider Electric SR2B121BD

Product Description:
SR2B121BD :Zelio Logic smart relays are designed for use in small automated systems. They are used in both industrial and commercial applications. For industry: automation of small finishing, production, assembly or packaging machines, decentralised automation of ancillary equipment of large and medium-sized machines in the textile, plastics and materials processing sectors, automated systems for agricultural machinery. For the commercial⁄building sectors: automation of barriers, roller shutters, access control, automation of lighting installations, automation of compressors and air conditioning systems. Their compact size and ease of setting-up make them a competitive alternative to solutions based on cabled logic or specific cards. Simple programming, ensured by the universal nature of LADDER and function block diagram FBD languages, meets all automation requirements and also the needs of the electrician. Compact smart relays are suitable for simple automated systems, up to 20 I⁄O.

The SR2B121BD is a Zelio Logic Compact Smart Relay with display. It has a backup memory which allows programs to be copied into another smart relay (examples for building identical equipment, remote transmission of updates). The memory also allows a backup copy of the program to be saved prior to exchanging the product. When used with a smart relay without display or buttons, the copy of the program contained in the cartridge is automatically transferred into the smart relay at powerup. The Autonomous operating time of the clock, ensured by a lithium battery, is 10 years. Data backup (preset values and current values) is provided by an EEPROM Flash memory. A module for communication on the Modbus network will be available for Zelio Logic modular smart relay. It is supplied with 24V via the smart relay. It is designed for monitoring or remote control of machines or installations which operate without personnel.
