ABB TP857 (3BSE030192R1) – Thin Client Operator Panel for System 800xA HMI Stations

The ABB TP857-3BSE030192R1 is an industrial thin client panel typically used as an operator interface in ABB System 800xA environments. From my experience, teams choose the TP857 when they want a reliable, panel‑mounted HMI front end without managing a full industrial PC in the cabinet. It’s built for 24 VDC operation, fanless performance, and a rugged, glove-friendly touch front – in many cases with IP65 protection at the bezel – which makes it a solid fit for process areas and utilities control rooms.

You might notice that the TP857 behaves like a dedicated terminal: it runs as a thin client to connect to server-based operator stations (RDP/ICA), so there’s no field I/O onboard to worry about. One thing I appreciate is the straightforward installation—panel mount the unit, feed 24 VDC, plug in Ethernet, and you’re basically ready to enroll it into the 800xA environment. It seems to be the pragmatic option when lifecycle, serviceability, and low heat dissipation matter.

Company’s Order Placement Process and Guarantees

Key Features

• Industrial thin client HMI – Designed to act as an operator interface for ABB System 800xA stations via server sessions (RDP/ICA).
• 24 VDC power input – Typically fed from the control cabinet’s 24 VDC bus for consistent uptime.
• Fanless, solid-state design – Reduces moving parts and maintenance in dusty or vibration-prone areas.
• Industrial touchscreen – Resistive touch front in many cases supports gloved operation; suitable for process lines.
• Ethernet-based connectivity – Simple tie-in to control networks; supports common thin client protocols used in 800xA.
• Panel-mount, IP-rated front – The front bezel typically meets IP65 when correctly installed with the gasket.
• Lifecycle and service – Built for long availability and straightforward field replacement.

Application Fields

The TP857 is typically deployed wherever 800xA is the control backbone:

• Oil & gas, chemicals, and petrochem plants needing sealed front panels on operator doors
• Power generation and water/wastewater plants where thin client stations simplify patching
• Pulp & paper, mining & metals lines with 24/7 operator consoles
• Pharma and food facilities that prefer glove‑friendly HMI fronts

A customer recently noted that swapping a legacy panel for TP857 cut their cabinet heat load and they stopped replacing failed fans. That’s a small thing day one, but over a year it adds up.

Advantages & Value

• Reliability – Fanless design and simplified OS image reduce failure points.
• Compatibility – Plays nicely with 800xA thin client and domain policies; no awkward workarounds.
• Lower lifecycle cost – Fewer moving parts, less patching overhead versus full industrial PCs.
• Service & spares – Straight swap in most cabinets; standardized 24 VDC and Ethernet minimize change effort.

Installation & Maintenance

• Cabinet & mounting – Install on a flat, rigid door or panel; use the supplied clamps and gasket. Keep clearances for cable bend radius and convection.
• Power & grounding – 24 VDC SELV/PELV; bond protective earth; avoid sharing supplies with inductive loads without proper filtering.
• Networking – Use shielded industrial Ethernet when possible; segregate control and corporate VLANs; follow 800xA network zoning.
• Environment – Operate within 0…50 °C typical; protect from direct spray on the rear, and prevent condensation.
• Routine care – Wipe the front with non‑abrasive cleaner; check bezel seal annually; update thin client firmware/images per site policy; touchscreen recalibration if pointer drift appears.

Quality & Certifications

• CE marking; RoHS compliance
• UL/cUL listings typically applicable for industrial panels (model/revision dependent)
• Manufactured under ISO 9001 quality systems
• Our warranty: 365 days from delivery

Related and Supporting Components

If you’re building out or refreshing an 800xA operator station cluster, these pair well with the TP857:

• ABB CP-E 24/5.0 – 24 VDC, 5 A industrial power supply; compact, reliable feed for a single panel.
• ABB CP-E 24/10.0 – 24 VDC, 10 A supply when multiple panels or accessories share the same rail.
• Panel mounting kit & gasket (TP8xx series) – Replacement clamps/seal to maintain IP65 at the front bezel.
• Industrial Ethernet switch (managed) – For control network segmentation and redundancy; select models with QoS and IGMP snooping for HMI traffic.
• USB industrial keyboard/pointing device – Stainless or sealed types for washdown or dusty environments.
