Description

Human Machine Interface (HMI) is an essential part of process plants since it is one of the major ways through which humans and machines interact.
The TIDA-00343 reference design offers an HMI solution for harsh and hazardous area applications. In process plants, operators need to interact with an explosion-proof display/controller which is encapsulated in a screw-on metallic enclosure with a thick glass window for local read out and programming functions.

Thanks to the TIDA-00343 TI Design which uses MSP430™ microcontrollers (MCU) with CapTIvate™ technology the operator will be able to interact with the controller without the need of opening the enclosure saving time by avoiding work permit or plant shutdown.

Features
  • Four Robust Buttons Option Implemented
  • Variable Airgap between Buttons and Glass(1-2mm)
  • Finger Detection through 10mm Thick Glass
  • Work with Gloves and in Harsh Environment(Water, Oil, Dust, etc)
  • Temperature Range: -40°C to 85°C
  • Low Power(~10Hz Scan Rate): 240µA-avg
