The IC757C series represents Emerson's dedicated web-hosted HMI platform within the PACSystems RXi family. Unlike full Windows-based panel PCs, these ARM-powered devices run a lightweight Linux Yocto distribution with QT WebKit and Chromium browser engines — purpose-built for HTML5-based visualization served from a remote PAC or edge controller. Available in six sizes from 7″ to 24″, with indoor and sunlight-readable outdoor variants, they cover operator stations from compact machine-mounted displays to large-format overview screens.

How does a web panel differ from a full panel PC?

The IC757C runs an embedded ARM processor (iMX6 Freescale dual-core 1.0 GHz) with 2 GB DDR3 and 4 GB internal Flash — not an x86 CPU with Windows. It is designed to display web-hosted HMIs: the visualization application runs on a central PAC, edge controller, or server, and the IC757C renders it in a browser. This architecture centralizes application management, eliminates software deployment to individual operator stations, and reduces per-node hardware cost and complexity. For applications requiring local Windows-based computing, Emerson's IC758C panel PC series provides that alternative.

What are the indoor and outdoor (SLR) display options?

Standard indoor models (CSW prefix) deliver 350–500 cd/m² brightness. Outdoor Sunlight Readable models (COW prefix, available in 7″ to 15″) boost brightness to 1000 cd/m² for readability in direct sunlight. All models use LED-backlit PCAP touchscreens rated for 50,000 hours MTBF at 25 °C, with software-dimmable backlight control. Contrast ratios range from 800:1 to 5000:1 depending on screen size.

What certifications does the IC757C series carry?

The series is certified for hazardous locations (UL HazLoc Class 1 Div 2 / Class 2 Div 2 / Class 3 Div 1), explosive atmospheres (ATEX Zone 2/22, IECEx), and marine applications (ABS, BV, DNV GL, LR). This certification suite supports deployment in oil and gas, chemical processing, marine, and other regulated industrial environments without additional enclosure requirements for the HMI itself.
