Applications
- Digital signal acquisition: Acquires digital signals through 16 parameterizable 24 VDC inputs.
- Input diagnostics: Monitors supply voltage and detects wire breaks, diagnostic conditions, and group errors.
Key Features
- Digital input channels: 16 parameterizable digital inputs with a 24 V rated input voltage and IEC 61131 type 3 input characteristic.
- Input signal ranges: Signal 0: -30 to +5 V; signal 1: +11 to +30V, with a typical signal-1 input current of 2.5 mA.
- Input timing: Parameterizable delay values from 0.05 / 0.1 / 0.4 / 0.8 / 1.6 / 3.2 / 12.8 / 20 ms, plus a 30 to 500 μs delay depending on line length.
- Diagnostics: Module diagnostics include wire-break detection, supply-voltage monitoring, diagnostic alarms, readable diagnostic information, and group error indication.
- Supply and isolation: Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection. Channels are isolated from the backplane bus and tested with 750 V DC.
- Connection and installation: Usable with BU type A0 for 1-wire connection; 2-wire, 3-wire, and 4-wire connections require BU type A0 plus a Potential distributor module. The module is rail-based and has conformal coating.
