It carries 12 discrete inputs rated for 100–240 V AC and includes a relay output rated for 10 A (resistive). The unit performs a program memory integrity check on every power-up, and its cycle time ranges from 6 to 90 ms depending on program size and logic type. This relay is sized for standalone control of small machines, conveyors, or lighting panels. The front panel carries IP40 protection, terminals are IP20. Supply is 100–240 V AC, 50/60 Hz, consuming 11 VA without extension modules.","metaTitle":"Schneider SR2B201FU Zelio Logic Smart Relay, Real-Time Clock","metaDescription":"Compact smart relay with 12 inputs, 100-240 VAC, real-time clock, program memory check.
