I-87H17W

8-channel HART Current input Module
     
 

The I-87H17W is a HART analog input module. It can measures 4~20mA current and acts as a HART master, allowing communication with HART field devices. Its user-friendly design saves a lot of work when measuring current due to a built-in resistor. Now, users can measure current directly without any external resistor. The baud rate of I-87H17W is changeable and supports DCON protocol. Otherwise, ICP DAS also provides API library for users to develop their own program by VC,VB , C# or VB.Net environment.

  
 
 
   
  • Current Measuring
  • Petrochemical Industry Application
  • Environment Monitoring
  • Tunnel Monitoring
  • Building Monitoring etc.

The XPAC-8000 controller and I-87H17W with eight HART AI channels are used to collect these HART manometers data quickly and easily. Through Ethernet, the control center can monitor all gas pipeline pressure remotely.
