The Schneider Electric SR2B201FU is a Zelio Logic compact smart relay with 20 I/O, supplied at 100…240 V AC, with a built-in display and real-time clock. Per the Schneider data sheet it has 12 discrete inputs and 8 relay outputs, and it is programmed in ladder (up to 240 lines) or FBD (up to 500 blocks).
Zelio Logic relays replace timers, counters and simple PLCs in small automation tasks: pump alternation, lighting and heating control, gates, small conveyors and alarm logic. The program can be written on the front keypad or with the free Zelio Soft software.

Compatibility and replacement
Match the supply voltage (100…240 V AC) and the I/O count of the old relay. Programs from an older Zelio Logic SR2 can be loaded with Zelio Soft if you have the file or a memory cartridge.
Frequently asked questions
Do I need software to program it?
No. It can be programmed from the front keypad and display. Zelio Soft makes larger programs easier.
Can I add more I/O?
This is a compact (non-extendable) model. For more I/O Schneider offers the modular SR3 range.
