Applications
- AC digital signal acquisition: The module acquires 8 AC digital input signals.
Key Features
- 8 isolated digital inputs: The module has 8 AC digital inputs with potential separation between the channels, in groups of 1.
- AC input signals: Input voltage is AC, with rated values of 120 V and 120/230 V AC (47 … 63 Hz). Signal 0 is 0 to 40V and signal 1 is 79 to 264V.
- Input current: Typical input current for signal 1 is 7.5 mA at 120 V and 17.3 mA at 230 V. The permissible quiescent current for a 2-wire sensor is max. 2 mA.
- Backplane and isolation: Input current from the backplane bus is max. 100 mA at 5 V DC. Separation from the backplane bus is provided by an Optocoupler, with isolation tested with 1 500 V AC.
- Signal timing and indication: At signal transitions, the maximum time is 25 ms from 0 to 1 and 25 ms from 1 to 0. The digital input status indicator is green.
- Connection and installation: The required front connector is 40-pin. Horizontal installation is up to 60 °C, max. 8; vertical installation is up to 40 °C, max. 8. Dimensions are 40 mm × 125 mm × 120 mm.
