Schneider Electric SR3B102BD | Relay & Timer

SR3B102BD Schneider Electric - Modular Smart Relay Zelio Logic SR3 - 10 I/O - 24V DC - with Clock - with Display - 4 Transistor Outputs. The Schneider Electric SR3B102BD is a modular smart relay from the Zelio Logic SR3 series, designed for simple automation system management with expandable I/O capability. It features 6 discrete inputs (24V DC, 4 usable as analog inputs with 0-10V range) and 4 transistor outputs, providing 10 total I/O points. The relay operates on 24V DC supply with a power consumption of 4W without extension and includes a backlit LCD display with contextual navigation buttons for on-site programming and monitoring. It includes a real-time clock for time-based automation functions. It supports both Function Block Diagram (FBD) and Ladder Diagram (LD) programming and mounts on standard DIN rail with screw terminals. The transistor outputs provide 24V DC at 0.625A per channel with short-circuit and overvoltage protection, and a response time of 1ms or less. The module is rated IP20 on the terminal block and IP40 on the front panel, with an operating temperature range of -20 to +55 degrees Celsius. Built-in EEPROM flash memory provides data backup up to 10 years for easy recovery after power interruption.
