Selection Notes

The SR2B121B is the 24 V AC member of the 12-I/O Zelio Logic SR2 compact range, with a built-in real-time clock for time-based control such as scheduled lighting or pump cycling. Where fewer or more I/O points are needed, the 10-I/O and 20-I/O SR2 variants in the same family cover the range without changing the programming environment.
