Product Description
Key Features
- Digital input capacity: 32 parameterizable digital inputs in groups of 16; above +60 °C, a maximum of 16 inputs can be controlled simultaneously.
- 24 VDC input and supply: Rated supply and input voltage: 24 V DC. Permissible supply range: 19.2 V to 28.8 V DC. Input signal "0": -30 to +5 V; input signal "1": +11 to +30V.
- Input processing: Input delay is parameterizable from 0.05 / 0.1 / 0.4 / 1.6 / 3.2 / 12.8 / 20 ms. The input characteristic curve complies with IEC 61131, type 3.
- Diagnostics and interrupts: The module has diagnostics, diagnostic alarms, hardware interrupts, supply-voltage monitoring, wire-break diagnosis to I < 350 μA, and RUN, ERROR, PWR and channel-status LEDs.
- Product identity and lifecycle: SIPLUS S7-1500 DI 32x24VDC HF based on 6ES7521-1BL00-0AB0, with conformal coating, -40…+70 °C, firmware V1.0.0, and Active Product lifecycle.
- Connections and isolation: Maximum cable length is 1 000 m shielded or 600 m unshielded. The channels are electrically separated in groups of 16 and separated from the backplane bus.
Applications
- Digital input acquisition: The module provides parameterizable digital inputs for signal acquisition.
- Counter operation: The module supports counter operation with up to 2 counters, a maximum counting frequency of 3 kHz under FS04 and FW V2.2.1 or higher, and 32-bit counting width.
- Diagnostic and interrupt signaling: The module supports diagnostic alarms, hardware interrupts, supply-voltage monitoring and wire-break diagnosis.
