Applications
- Digital signal acquisition: Acquires signals from NAMUR encoders and changeover contacts through 8 digital input channels.
- Counter operation: Counts input signals with up to 4 counters, 5 kHz maximum counting frequency, and selectable up/down counting direction.
Key Features
- Digital input channels: 8 parameterizable NAMUR digital inputs support DI and counter operation.
- Counter function: Up to 4 counters are supported, with a maximum counting frequency of 5 kHz and 32-bit counting width.
- Supply and current: Rated supply is 24 V DC, with a permissible range of 19.2 V to 28.8 V DC and maximum current consumption of 70 mA.
- Diagnostics: Channel-by-channel diagnostics include wire-break and short-circuit detection, diagnostic alarms, and hardware interrupts on channels 0 to 7.
- NAMUR encoder supply: The module provides 8.2 V NAMUR encoder supply with a maximum output current of 8 mA per channel.
- Connection and isolation: BU type A0 is supported for 2-wire and 3-wire connections; channels are isolated from the backplane bus and load voltage L+.
