Applications
- Digital signal acquisition: Acquires 24 V DC digital signals through 8 Sink/Source digital inputs.
- Digital output control: Controls digital loads through 8 transistor outputs with 0.5 A rated output current.
Key Features
- Digital I/O configuration: 8 digital inputs and 8 digital outputs; product type designation: SM 1223, DI 8×24 V DC, DQ 8×24 V DC.
- 24 V DC input signals: Input rated value is 24 V DC. Signal "0" is 5 V DC at 1 mA, while signal "1" is 15 V DC at 2.5 mA.
- Transistor outputs: 8 transistor outputs provide a 0.5 A rated output current and 0.5 A maximum permissible range for signal "1".
- Supply and power: Rated supply voltage is 24 V DC, with a permissible range from 20.4 V to 28.8 V DC. Typical power loss is 2.5 W.
- Diagnostics and protection: Diagnostic alarms are available, with LEDs for input and output status. Digital outputs have no internal short-circuit protection; this must be provided externally. Protection degree is IP20.
- Isolation and installation: Digital input potential separation is provided in groups of 2; digital output separation is in groups of 1 and 500 V AC between outputs and the backplane bus.
