Product Overview

The SR2B121FU is a Zelio Logic Compact Smart Relay with display, a connecting cable and Zelio Soft programming software supplied on CD-ROM. 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.
