Applications
- Digital signal acquisition: Acquires digital signals through 8 sourcing inputs with parameterizable input delay and supply-voltage diagnostics.
Key Features
- Digital input channels: 8 parameterizable sourcing inputs with a 24 V DC rated input voltage and IEC 61131 type 1 input characteristic.
- Signal ranges: Signal "0": 30 V to -5 V; signal "1": -11 V to -30 V, with reference potential L+.
- Input timing: Parameterizable input delay: 0.05 / 0.1 / 0.4 / 0.8 / 1.6 / 3.2 / 12.8 / 20 ms, plus 30 to 500 μs depending on line length.
- Diagnostics: Supply-voltage monitoring, diagnostic alarms, readable diagnostic information, green PWR and channel LEDs, and a green/red DIAG LED.
- Supply and protection: Rated supply voltage: 24 V DC; permissible range: 19.2 V to 28.8 V DC; reverse polarity protection: Yes.
