  • Page 7: General Information

    SECTION 1 • GENERAL INFORMATION GENERAL The BE1-49 Temperature Relay is a solid-state device that monitors the temperature of a remotely located resistive temperature detector (RTD), and provides signals to the protective scheme when the sensed temperature goes above or below predetermined limits. A variety of output options provide a selection of latching or non- latching types of normally open or closed contacts.

    Figure 3-1. Functional Block Diagram Power Supply Basler Electric enhanced the power supply design for unit case relays. The new design created three, wide- range power supplies that replace the six previous power supplies. Style number identifiers for these power supplies have not been changed so that customers may order the same style numbers that they ordered previously.
