Product details

The Schneider SR2B201FU is a Zelio Logic compact smart relay with a built-in real-time clock (RTC) that supports time-based sequencing and logging. 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.

Frequently asked questions

What is the real-time clock accuracy?

Clock drift is specified at 12 min/year over 0–55 °C, or 6 s/month at 25 °C.

What compliance documentation is available for the SR2B201FU?

It conforms to IEC 61000-6-2, -3, -4, IEC 61131-2 (both EMC and Low Voltage directives), and radiated/conducted emissions at Class B per EN 55022-11. The unit also meets several immunity standards (IEC 61000-4-2/3/4/5/6/11/12 and shock/vibration per IEC 60068-2-27/6).
