Product information
Overview
Key Features
- 8-channel HART analog input: The AI 8xHART HF module has 8 analog inputs, all for current measurement, arranged in groups of 4.
- Current input ranges: Supported rated input ranges are 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA, with 125 Ω input resistance.
- Accuracy and resolution: Accuracy is 0.1% relative to the input range without HART communication, with up to 16 bit resolution including overrange and sign.
- Diagnostics and alarms: The module has diagnostics, diagnostic alarms, limit value alarms, supply voltage monitoring, wire-break detection for 4 mA to 20 mA channel by channel, and overflow/underflow detection.
- Supply and protection: Rated supply is 24 V DC with a permissible range of 19.2 V to 28.8 V DC and reverse polarity protection. Common mode voltage is 60 V DC/30 V AC.
- Included delivery items: Delivery includes an infeed element, shielding bracket and shield terminal.
