ICP DAS I-87H17W - 8 Channel HART Current Input Module
by ICP DAS

8-channel HART Current Input Module

Description
Specification
Datasheet

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 sampling 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.
