Applications
- Digital signal acquisition: Acquires digital signals through 8 parameterizable 24 V DC inputs with rising-edge, falling-edge, and edge-change evaluation.
Key Features
- Digital input channels: 8 parameterizable digital inputs with 24 V DC rated input voltage and IEC 61131 type 3 input characteristics.
- Input signal ranges: Signal 0: -30 to +5 V; signal 1: +11 to +30 V; typical input current for signal 1 is 2.5 mA.
- Encoder supply: 8 encoder-supply outputs provide a minimum output voltage of 19.2 V; short-circuit protection is provided per channel.
- Input delay: Parameterizable delay is 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.
- Channel diagnostics: Diagnostics include encoder power supply short circuit, wire break, supply voltage, and channel fault LED indication.
- Connection and BaseUnit: BU type A0 supports 1-wire and 2-wire connections; 3-wire connection requires BU type A0 with AUX terminals or a potential distributor module, while 4-wire connection requires BU type A0 + Potential distributor module.
