Applications
- Digital signal acquisition: Acquires digital input signals through 8 parameterizable 24 V DC inputs with P-reading.
Key Features
- Digital inputs: 8 parameterizable digital inputs with P-reading and input characteristics according to IEC 61131 types 1, 2, and 3.
- Input voltage: Rated input voltage is 24 V DC; signal 0 is -30 to +5 V and signal 1 is +11 to +30V.
- Input delay: For standard inputs, the 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.
- Interfaces and engineering: Suitable for operation on PROFINET R1 IMs; configurable or integrated with STEP 7 TIA Portal from V14 and STEP 7 from V5.5 SP3 / -.
- Diagnostics and LEDs: Provides supply-voltage diagnostics, diagnostic alarms, group error information, a green PWR LED, green channel-status LED, and green/red DIAG LED.
- BaseUnit and installation: Uses BU type A0 for 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.
