SR3XT61B
- Reverse polarity protection
- Simple ladder programming, adapted for non-specialists
- Discovery package, coming with Zelio Soft programming software: the simplest way to learn and use this relay
- Built-in EEPROM flash memory for data backup up to 10 years: easy-to-recover after a power shortage or incident
- More I/O than SR2 model, for larger applications
-
