Applications
- Digital signal acquisition: Uses 2 current-sourcing digital inputs for digital signal acquisition.
- Digital output control: Uses 2 MOSFET solid-state digital outputs for current-sinking/current-sourcing output control.
Key Features
- Digital I/O channels: Has 2 current-sourcing digital inputs and 2 MOSFET solid-state digital outputs, with 2 inputs and 2 outputs in each group.
- 24 V DC signals: Rated input voltage is 24 V DC; rated output voltage is 24 V DC.
- High-speed output capability: The product description specifies 200 kHz capability for the SB 1223 Digital I/O.
- Parameterizable inputs: Standard inputs are parameterizable with selectable times from 0.1 μs to 20.0 μs and from 0.05 ms to 20.0 ms.
- Output protection and diagnostics: The outputs have no short-circuit protection. LED diagnostics indicate input and output status.
- Cable length: Maximum shielded cable length is 50 m; the input specification also requires shielded, twisted pair cable.
