Schneider Electric SR3B101BD | Relay & Timer

SR3B101BD Schneider Electric - Modular Smart Relay Zelio Logic SR3 - 10 I/O - 24V DC - with Clock - with Display - 4 Relay Outputs. The Schneider Electric SR3B101BD 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 relay outputs, providing 10 total I/O points. The relay operates on 24V DC supply with a power consumption of 3W 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 relay outputs feature NO contacts with output voltage range of 5-30V DC and 24-250V AC, thermal current of 8A for all 4 outputs, and electrical durability of 500,000 cycles. 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.
