  • CLIENT: Schrack Technik

 

The product consists of two parts. AIL15-M in tandem with AIL15-S is a modular system designed to monitor 1 to 16 pieces of three-phase outputs in the low voltage network. The AIL15-M measurement unit is evaluating, processing and publishing data gathered from AM15-S.

AIL15-M

AIL15-M concentrator is gathering data from up to 16 pieces of AIL15-S measurement units. The measured data from every measurement unit - voltage, current, effective power, idle power - is calculated and evaluated. The output values are published through the RS-485 Modbus interface and sent to the FTP server.

Communication interfaces:

  • Ethernet RJ45

  • Modbus RS-485

    • without galvanic separation

    • communication speed 115 200 Bd 8N1

AIL15-S RS-485

  • with galvanic separation

  • 5000 V isolation voltage according to UL1577

  • proprietary, address protocol
