Applications
- Digital signal acquisition: Acquires digital signals from connectable 2-wire sensors through 8 digital inputs.
Key Features
- Digital inputs: 8 digital inputs with a DC input voltage type and 24 V rated value.
- Input signal ranges: Signal "0": -30 to +5 V; signal "1": +15 to +30 V.
- 2-wire sensor connection: 2-wire sensors are connectable; permissible quiescent current is 1.5 mA max.
- Input timing: For standard inputs, transitions are 2 ms min. to 4.5 ms max. from "0" to "1" and from "1" to "0".
- Isolation and indication: Digital inputs are isolated from the backplane bus and have a green digital-input status LED; the channels are not isolated from each other.
- Supply and protection: Rated supply voltage is 24 V DC with reverse polarity protection. Typical power loss is 1.2 W.
