Selection Notes

The SR2B201BD is the 24 V DC member of the 20-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 and 6 of its inputs configurable as 0-10 V analogue channels for simple threshold or setpoint monitoring. Where less I/O is needed, the smaller 10- and 12-I/O SR2 variants in the same family save panel space without changing the programming environment.
