Product information
Overview
Key Features
- 16 relay outputs: The SM 1222 has 16 digital relay outputs, in groups of 1.
- 2 A rated output current: Output current for signal "1" is 2 A; switching capacity with a resistive load is 2 A max.
- DC and AC output voltage: Rated output voltage is 5 V DC to 30 V DC or 5 V AC to 250 V AC.
- Relay coil supply: The rated supply voltage of relay coil L+ (DC) is 24 V.
- Diagnostics and protection: The module has a diagnostic alarm, output-status LED indication, relay potential separation, and IP20 protection. Short-circuit protection is not included and must be provided externally.
