The IS1+ remote I/O system is designed for data transmission in hazardous areas (Zones 1 and 2). Its integrated predictive maintenance and diagnostics features help ensure maximum process availability. The fully intrinsically safe structure with an intrinsically safe fieldbus based on Profibus DP or industrial Ethernet Modbus TCP, EtherNet/IP or Profinet facilitates system expansion or modification in hazardous areas: modules can be hot-worked or hot-swapped at any time. The system includes such multifunctional modules as an eight-channel module for analog inputs and outputs with HART, a 16-channel module for digital inputs and outputs or an eight-channel temperature module for 26 temperature sensors.
