Applications
- Digital signal acquisition: Acquires digital signals through 8 inputs with defined AC/DC signal thresholds.
Key Features
- Digital inputs: 8 digital inputs with P-reading sourcing/sinking input and an IEC 61131 type 1 input characteristic curve.
- Signal thresholds: Signal 0: AC/DC < 10 V. Signal 1: AC > 14 V, DC > 34 V; typical input current for signal 1 is 3.5 mA.
- Supply voltage: Rated supply: 48 V DC, or 48 V; 24 V/48 V; 50 Hz/60 Hz AC. Permissible range: 40.8 V to 57.6 V DC and 40.8 V to 52.8 V AC.
- Interfaces and engineering: Suitable for operation on PROFINET R1 IMs. STEP 7 TIA Portal is configurable/integrated from V15; STEP 7 from V5.6.
- Diagnostics: Module diagnostics, diagnostic alarms, readable diagnostic information, supply-voltage and encoder-power monitoring, group error, green PWR and channel LEDs, and green/red DIAG LED.
- Connection and installation: Suitable for BU type U0. 1-wire and 2-wire connections use BU type U0; 3-wire and 4-wire connections require BU type U0 plus a Potential distributor module.
