Applications
- Digital signal acquisition: Acquires 24 VDC digital signals through 16 parameterizable input channels.
- Counter operation: Counts input events using up to 2 counters at a maximum counting frequency of 6 kHz.
- Input event handling: Supports parameterizable interrupt inputs, hardware interrupts, and diagnostic alarms.
Key Features
- 16-channel digital input: DI 16x24VDC HF provides 16 digital inputs in groups of 16 with parameterizable inputs and IEC 61131 type 3 characteristics.
- 24 VDC signal ranges: Input rated value is 24 VDC; signal 0 is -30 to +5 V and signal 1 is +11 to +30 V.
- Configurable input delay: Standard input delay is parameterizable from 0.05 / 0.1 / 0.4 / 1.6 / 3.2 / 12.8 / 20 ms, with 0.05 ms minimum and 20 ms maximum.
- Diagnostics and interrupts: The module has diagnostics, diagnostic alarms, hardware interrupts, supply-voltage monitoring, wire-break detection to I < 350 μA, and channel and module diagnostic LEDs.
- Counter operation: Counter mode supports up to 2 counters, a maximum counting frequency of 6 kHz, 32-bit counting width, and upward counting direction.
- SIPLUS construction: The module has conformal coating and a -40…+70 °C range, with OT4 and ST1/2 (+85 °C for 10 minutes).
