Mechanical data: Die‑cast powder‑coated aluminum housing; cabinet cut‑out dimension 324 mm × 252 mm; net weight approx 2.5 kg; certifications: CE, UL/cULus, DNV marine approval.
Real‑time process graphic visualization, numeric value, bar‑chart and status‑indicator display. 20 hardware function keys support quick shortcut operation for frequent field operations. Multi‑level user password access management, alarm and event logging, historical trend curve display, recipe storage and download. Multi‑language text support and offline simulation function are available within Panel Builder 800 software. Optimized for native System 800xA object‑oriented communication.
Difference compared with PP845: PP846A is equipped with 20 physical LED function keys; PP845 is pure touch‑screen panel without hardware keys. Both are 10.4‑inch size and belong to Panel 800 series for System 800xA DCS. PP846A is revised hardware successor of PP846.
Cabinet flush‑mount installation. Confirm cabinet cut‑out dimension complies with mechanical drawing and fit front‑panel sealing gasket properly to guarantee IP66 front‑panel protection. Separate signal cables from high‑power cables to reduce electromagnetic interference. After panel replacement, download complete HMI application project, verify Ethernet communication with AC 800M controller and normal process‑data display. Periodically replace internal backup lithium battery (CR2450) to prevent RTC clock and recipe‑data loss.
Power‑plant control rooms, pulp‑and‑paper mills, chemical plants and general process‑industry facilities, deployed as local operator panel for on‑site process monitoring and frequent quick parameter adjustment under System 800xA DCS system.
- ABB Panel 800‑series revised A‑version 10.4‑inch operator panel combining resistive touch screen and 20 programmable LED function keys for System 800xA DCS environment.
- Rich onboard interfaces: Ethernet, dual‑serial, dual‑USB and CF‑card expansion slot for flexible device connection and data storage.
- Die‑cast aluminum housing, front‑panel IP66 protection, suitable for dusty and humid process‑industry environments.
