Applications
- Electronic weighing: Provides electronic weighing with a non-automatic weighing instrument using DMS full-bridge load cells.
- Load-cell communication: Connects the weighing module to SIWATOOL V7, SIWAREX DB, or a SIEBERT remote display through RS 485.
Key Features
- 1-channel load-cell input: Connects DMS full-bridge load cells with 4-conductor or 6-conductor connections and supports 1 mV/V to 4 mV/V measuring ranges.
- RS 485 interface: 1 RS 485 interface supports SIWATOOL V7, SIWAREX DB, or a SIEBERT remote display, with transmission rates up to 115.2 kbit/s.
- High input resolution: Load-cell input resolution is ±500 000 parts per mV/V, with a 600 Hz sampling rate.
- 24 V supply: Rated supply voltage and load voltage L+ are 24 V DC; the permissible load-voltage range is 19.2 V DC to 28.8 V DC.
- Diagnostics and alarms: Supports diagnostic alarms, parameterizable hardware interrupts, supply-voltage monitoring, wire-break, short-circuit, and group-error diagnosis.
- SIPLUS environmental design: Has conformal coating and a temperature range of -40…+60 °C.
