The 10-year backup at the same temperature keeps the clock and program memory through extended power outages; no battery replacement hits the maintenance window. Cycle time runs 6…90 ms in ladder, fast enough for simple sequences and interlock loops on a process skid or small panel. ## Installation integration notes Rated supply is 24 V AC (20.4…28.8 V, 50/60 Hz). Power draw: 4 VA without extension modules, 7.5 VA with. Screw terminals accept 1 x 0.2…2.5 mm² solid or flexible with ferrule. IP40 front panel, IP20 on terminals. Isolation voltage 1780 V. 6 discrete inputs at 24 V AC, 4.4 mA each. Relay output mechanical durability 10 million cycles.","metaTitle":"Schneider SR3B101B Zelio Logic Smart Relay, RTC, 24 VAC","metaDescription":"SR3B101B modular smart relay with real-time clock, 6 inputs, relay outputs, 24 VAC.
