Emerson IC755CSS15CDA – 15-inch Industrial HMI

• 15-inch TFT LCD (XGA class) – A bright, 4:3 display that typically delivers crisp 1024×768 graphics for clear P&IDs and trend views.

• Resistive single-touch – Works reliably with gloved hands; you might notice fewer mis-taps in oily or dusty environments.

• 24 VDC power – Standard industrial supply range, simplifying cabinet power design and spares management.

• Industrial protection – Front panel rated for harsh factory settings (IP/NEMA front sealing), suitable for washdown splash zones indoors.

• Versatile connectivity – Ethernet for plant networks, RS‑232/485 for legacy devices, plus USB for data backup and service tools.

• Driver flexibility – In many cases, connects to major PLC brands via well-known protocols like Modbus (TCP/RTU) and EtherNet/IP.

• Recipe, alarms, and logging – Built-in functions that reduce external PC dependencies and day-to-day operator workload.

• Panel-mount, slim depth – Easy drop-in on new or retrofit panels with standard clamp hardware and a replaceable gasket.

This model fits mid-to-large operator stations on packaging, material handling, and metal forming lines where the larger screen cuts down on page switching. It also shows up a lot in water/wastewater and utilities, typically for clear mimic diagrams and audit-friendly alarm lists.    One integrator told me they prefer this unit on food & beverage skids (indoor washdown areas) because the front sealing handles routine cleaning without drama.

• Lifecycle confidence – Stable platform and long-availability parts help reduce redesign risk during plant standardization.

• Compatibility – Broad driver support eases migrations from older GE/Emerson HMIs or mixed-vendor PLC fleets.

• Lower total cost – No extra industrial PC for basic logging/recipes; fewer moving parts typically means less field service.

• Maintainability – Replaceable front gasket and straightforward panel clips; technicians usually finish a swap in under an hour.

• Operator acceptance – The resistive touch seems to be more forgiving with gloves and humidity than capacitive panels in many cases.

• Panel and cabinet – Mount on a rigid metal panel with a clean cutout; use the supplied gasket and clips evenly. Provide ventilation to keep the HMI within 0–50 °C.

• Power wiring – Feed from a regulated 24 VDC Class 2/SELV source with a dedicated protective earth. Keep Ethernet/serial cables separated from motor and VFD leads.

• Network & protocols – Assign static IPs for machine networks; validate driver versions for the PLCs you intend to connect (e.g., Modbus TCP/RTU, EtherNet/IP).

• Safety & ESD – Power down before swapping SD cards or USB devices. Confirm enclosure bonding to avoid touch-screen drift caused by noise.

• Routine care – Wipe the screen with a lint-free cloth; avoid abrasive cleaners. Inspect the front gasket during shutdowns and replace if it shows compression set.

• Firmware & backups – Keep a verified runtime image and recipe/alarm backups on secure media; plan periodic firmware and driver updates during scheduled stops.

• CE marked; designed for EMC and LVD compliance for industrial environments

• UL/cUL listing for industrial control equipment (indoor use)

• RoHS compliant materials; WEEE considerations for end-of-life handling

• Manufacturer’s limited warranty: typically 12 months from shipment

• Replacement front gasket – Maintains IP/NEMA seal after multiple services.

• Panel-mount clip kit – Handy to keep a spare set for fast changeovers.

• Industrial 24 VDC DIN-rail power supply – Sizing depends on total cabinet load; choose units with low ripple for HMI stability.

• Shielded Ethernet patch cords – Reduces noise pickup, especially near drives.

• USB service drive – For backups, recipe sets, and event logs.

Field note: A packaging OEM shared that moving to the IC755CSS15CDA cut their operator training time by roughly 20%—largely because the larger screen let them consolidate three screens into one with clearer alarms and bigger trend plots.
