Product Description
Key Features
- Analog input configuration: 4 differential analog current inputs support 2-wire and 4-wire transducers.
- Input ranges and resolution: Supported current ranges are 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA; resolution is up to 16 bit including sign.
- Supply and encoder output: Rated supply is 24 V DC, with a permissible range of 19.2 V to 28.8 V. Encoder supply is 24 V with short-circuit protection.
- Module identity and mounting: Product type designation is AI 4xI 2-/4-wire ST. It uses BU type A0, A1 and has a Type A mechanical coding element.
- Diagnostics: The module has supply-voltage monitoring, wire-break detection at 4 mA to 20 mA, short-circuit detection, group error, and overflow/underflow diagnostics.
- Firmware and engineering: FW update is possible. STEP 7 TIA Portal is configurable/integrated from V14 / -, STEP 7 from V5.6 and higher, and PCS 7 from V8.1 SP1.
Applications
- Current measurement with 2-wire transducers: Supports current measurement as a 2-wire transducer with a maximum transmitter burden of 650 Ω.
- Current measurement with 4-wire transducers: Supports current measurement as a 4-wire transducer.
