Smart relay with built-in RTC and display
The Schneider Electric SR2PACKFU is a Zelio Logic compact discovery pack combining a smart relay with 12 I/O: 8 discrete inputs (100-240 VAC, 0.6 mA) and 4 relay outputs. It runs on 100-240 VAC supply, 50/60 Hz, and has a cycle time of 6 to 90 ms. A local display and real-time clock are included; the clock maintains time for 10 years at 25°C without power, with drift of 12 min/year over 0-55°C or 6 s/month at 25°C. The base unit checks program memory on each power-up.
Supply voltage limits are 85-264 VAC, so it handles nominal 120 V or 240 V lines with brownout margin. At 240 V the module draws 30 mA (without extension); at 100 V it draws 80 mA. Inputs are 100-240 VAC, sinking 0.6 mA each — straight off the line, no separate sensor supply needed. Relay outputs switch at 0.1 Hz at rated current (10 Hz no-load), mechanical durability 10 million cycles. Isolation voltage 1780 V. IP20 on terminals, IP40 front panel.
