ABB 1SVR440713R0100 Logic Relay

The ABB 1SVR440713R0100 Logic Relay is the eight-digital-input, four-relay-output module in ABB’s 1SVR family, mapping to the CL-LSR.12AC2 configuration. This ASEA BROWN BOVERI device provides eight digital inputs that monitor sensors or switches and two analogue inputs that can be used alongside its internal logic for basic signal processing and decision-making. With four relay outputs, the module can directly switch actuators or indicators in compact control panels, enabling localized control without a separate PLC. The CL-LSR.12AC2 configuration is designed to support simple control tasks in industrial environments, offering a modular approach to automation where expansion and customization are common. The 1SVR family is built to operate within ABB automation ecosystems, allowing integration with other 1SVR logic relays and standard ABB accessories for mounting and wiring. Whether used for threshold-based control, sequence logic, or basic interlocks, this module provides a compact, field-installable solution that minimizes panel space while delivering dependable, discrete control functionality.
