ABB RET615 Transformer Protection and Control Relay

Description

ABB RET615 Transformer Protection and Control Relay is a specialized device designed for transformer protection and control applications. Note: Direct technical specifications for this model are not available in provided search results. For reference, related ABB bus coupler modules like CI615 3BHT300024R1 offer comparable industrial automation functionality: this bus coupler serves as an I/O expansion unit interface, enabling connection of multiple I/O modules via a bus to enhance system controllability and flexibility. It is compatible with existing ABB controllers, supports configuration and monitoring via dedicated software, and includes built-in diagnostic functions for fault troubleshooting. Physical specifications for the CI615 variant include dimensions such as 252mm depth, 273mm height, 40mm width, and 1.2kg net weight, with another variant measuring 260mm depth, 25mm height, 122mm width, and 0.17kg net weight. These modules feature mechanical keying to prevent incorrect insertion and voltage/current damage, plus electronic identification IDs to ensure only matched modules operate with the ModuleBus host, supporting both single and redundant module setups for industrial automation systems.
