Applications
- Digital signal acquisition: Acquires 24 V DC digital input signals through 32 parameterizable channels.
- Counter operation: Provides up to 2 counters with a maximum counting frequency of 3 kHz, 32-bit counting width, and up counting direction.
- Input event handling: Supports gate start/stop, diagnostic alarms, and hardware interrupts for parameterizable digital inputs.
Key Features
- Digital inputs: 32 parameterizable digital inputs in groups of 16; above +60 °C, a maximum of 16 inputs can be controlled simultaneously.
- Input signals: 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, parameterizable delay is 0.05 / 0.1 / 0.4 / 1.6 / 3.2 / 12.8 / 20 ms, with a maximum of 20 ms.
- Diagnostics and interrupts: The module has diagnostics, diagnostic alarms, hardware interrupts, supply-voltage monitoring, wire-break detection to I < 350 μA, and RUN, ERROR, PWR, channel-status, channel-diagnostic, and module-diagnostic LEDs.
- Supply and consumption: Supply voltage is 24 V DC, with a permissible range of 19.2 to 28.8 V DC and reverse-polarity protection. Maximum current consumption is 40 mA; power consumption from the backplane bus is 1.1 W.
- Isolation and installation: Channels are electrically isolated from each other in groups of 16 and from the backplane bus. Maximum cable length is 1 000 m shielded or 600 m unshielded.
