ABB YPC104B (YT204001-BT) – 10.4-inch Industrial Panel Computer / HMI for reliable machine and process control

The ABB YPC104B, ordering code YT204001-BT, is a compact 10.4-inch panel computer typically used as an HMI/industrial PC in machine lines, utilities, and process skids. From my experience, it fits nicely when you need a rugged, panel-mounted operator interface with solid connectivity (Ethernet and serial) and a clean front panel that holds up on the factory floor. You might notice that it slots into existing ABB DCS/PLC architectures with little fuss, making upgrades from older terminals fairly straightforward.

Key Features

• 10.4-inch panel-mounted design – A practical size for local operator stations where space is tight but readability still matters.
• Industrial-grade construction – Front-panel sealing typically rated for harsh environments; good choice for dusty lines and utility areas.
• Versatile connectivity – Ethernet plus RS-232/485 serial ports for legacy devices and field gateways. Helpful during phased upgrades.
• Touch operation – Usually resistive touch for gloved operation; quick access to key process screens and diagnostics.
• 24 VDC power – Standard in control cabinets; reduces the need for additional converters in most cases.
• Works well in ABB ecosystems – Commonly deployed with ABB DCS/PLC platforms, yet open interfaces make it flexible with third-party controllers.
• Service-friendly – Panel-mount clips and accessible I/O help speed up swap-outs, which maintenance teams appreciate on planned stops.

Technical Specifications

One thing I appreciate is how the YPC104B helps bridge old and new—serial for existing drives or weighers, Ethernet for SCADA and historians. A maintenance lead at a food plant mentioned they swapped to a YPC104-series unit without re-cutting the door, which saved them a surprising amount of downtime.

Related or Supporting Products

• ABB Panel 800 series (e.g., PP846, PP865, PP877) – Dedicated operator panels; often simpler runtime and lower power draw compared to a full panel PC.
• ABB CP600/CP600-Eco (e.g., CP651) – Modern HMI terminals with various screen sizes; a good option if you prefer pure HMI without Windows-class computing.
• 24 VDC power supplies (ABB CP-E series) – Stable DIN-rail supplies to feed the panel; choose appropriate current headroom for inrush.
• Industrial Ethernet switches (ABB / third-party) – Managed or unmanaged, depending on your SCADA/VLAN policy.
• Panel mounting kit and replacement gasket – Helps maintain the IP rating after service interventions.

Installation & Maintenance

• Cabinet and cutout – Use a rigid, low-vibration door. Follow the panel cutout specified for the 10.4-inch size; avoid over-tightening clips to keep the front seal intact.
• Ventilation – Provide free air space behind the unit; in most cases, fanless cooling is sufficient if ambient stays within 0–50 °C.
• Power wiring – 24 VDC with proper grounding and surge protection. Keep signal and power separated; use ferrules on conductors.
• Network/serial – Shielded cables for RS-485, with correct termination. For Ethernet, industrial-rated patch cords and strain relief help long-term reliability.
• Safety – De-energize before service. If the unit is in a washdown area, check gasket integrity after any maintenance.
• Routine maintenance – Clean the front with a soft, non-abrasive cloth; avoid solvents. Back up application images and configuration. Apply OS/runtime updates during planned shutdowns.
• Spares planning – Keep a spare gasket and an image of the application. In many cases, this reduces MTTR to under an hour.

Quality & Certifications

• CE marked; typically conforms to EMC and Low Voltage requirements for industrial environments
• UL/cUL listings for industrial control equipment (region-dependent)
• RoHS compliant
• Manufacturer’s warranty: 12 months (365 days)

If you’re refreshing older operator stations or standardizing across lines, the ABB YPC104B seems to be a safe, cabinet-friendly choice. It usually drops in cleanly and gives you enough I/O options to keep legacy devices talking while you modernize the rest.
