Product Description
Key Features
- Digital I/O configuration: SM 1223, DI 16×24 V DC, DQ 16×24 V DC, with 16 digital inputs and 16 digital outputs.
- 24 V DC supply: Rated supply voltage is 24 V DC, with a permissible range of 20.4 V to 28.8 V.
- Transistor output capacity: Outputs have a switching capacity of 0.5 A maximum with resistive load and 5 W maximum on lamp load.
- Input signal thresholds: Input voltage is 5 V DC at 1 mA for signal "0" and 15 V DC at 2.5 mA for signal "1".
- Installation-dependent capacity: The module supports 16 in all mounting positions up to 40 °C and 8 A current per mass for horizontal installation up to 50 °C.
- Protection and diagnostics: The module has IP20 protection, diagnostic alarms, and status LEDs for inputs and outputs; output short-circuit protection must be provided externally.
