SR2B202BD Schneider Electric - Compact Smart Relay Zelio Logic - 20 I/O - 24V DC - with Clock - with Display - 8 Transistor Outputs. The Schneider Electric SR2B202BD is a compact smart relay from the Zelio Logic SR2 series, designed for simple automation system management. It features 12 discrete inputs (24V DC, 6 configurable as analog 0-10V) and 8 transistor outputs, providing 20 total I/O points. The relay operates on 24V DC supply with a low power consumption of 3W and includes both a backlit LCD display and a real-time clock. It supports Function Block Diagram (FBD), Ladder Diagram (LD), and Sequential Function Chart (SFC) programming using the free Zelio Soft software and mounts on standard DIN rail with screw terminals. The transistor outputs provide 24V DC at 0.5-0.625A per channel with built-in overload, short-circuit, and overvoltage protection. 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.
