Product Description
Key Features
- Product identity: SIPLUS S7-300 SM 331 2AI HART based on 6ES7331-7TB00-0AB0 with conformal coating.
- Analog inputs: 2 analog inputs support rated current ranges of 0 to 20 mA and 4 mA to 20 mA, with 50 Ω input resistance for each range.
- Supply: Rated load voltage is 24 V DC. Transmitter supply is 15 V at 22 mA and is short-circuit proof at approximately 30 mA.
- HART and diagnostics: HART communication is active; diagnostics, diagnostic alarms, limit value alarms, overrange, wire-break, and short-circuit detection are supported.
- Ex(i) and protection: The module supports Ex(i) protection and has IP20 protection. Connecting-terminal maximums for gas group IIC include 26 V no-load voltage and 96.1 mA short-circuit current.
Applications
- Current measurement: Supports current measurement with 2-wire and 4-wire transducers.
- HART communication: Supports active HART communication for connected signal encoders.
- Signal diagnostics: Provides diagnostics for overrange, wire-break, short-circuit, and parameterizable alarms.
