Key Features
- Digital output type: SM 1222, DQ 16x relay/2 A with 16 relay outputs.
- Output voltage ranges: Rated output voltage: 5 V DC to 30 V DC or 5 V AC to 250 V AC.
- Output capacity: Maximum switching capacity with resistive load: 2 A; lamp load: 30 W with DC and 200 W with AC.
- Supply voltage: Rated supply voltage: 24 V DC, with a permissible range of 20.4 V DC to 28.8 V DC.
- Diagnostics and isolation: Diagnostics function, diagnostic alarm, supply-voltage monitoring, DIAG LED, and output-status LED are available. Digital outputs have relay potential separation between channels in groups of 8 and 1500 V AC type-test separation from the backplane bus.
- Timing and protection: Maximum output delay is 10 ms for both “0” to “1” and “1” to “0” with resistive load. Short-circuit protection is not included and must be provided externally.
