Description
MT-91-ARC FP A (MT91) — ABB Operator Panel
Product Overview
The MT-91-ARC FP A, identified on the nameplate as type MT-91 and ordered within the MT91 operator panel family, is an industrial human–machine interface panel manufactured by ABB’s German unit, ABB SST GmbH. Surplus dealers that have handled the physical units describe it consistently as an operator panel for robot control and industrial automation, while the same hardware appears in the used-market records as an MT91 alarm monitoring display panel — the two roles that define the unit: an operator display and annunciator for control systems that need live status, alarms, and operator input at the machine or console.
The panel communicates over industrial serial lines — RS-422/485, with V.24/RS-232-C also carried on the interface — and is powered from a 24 V DC supply, with the nameplate rating a maximum of 60 V / 0.5 A. These are the characteristics of a long-distance-capable, low-power operator terminal designed for integration into control cabinets and consoles rather than a desktop device. The ABB service identity for the panel is recorded as GATS 11 01 67 R 0401, with hardware article number 200010450702, giving maintenance organizations two unambiguous reference keys when sourcing the unit.
For facilities running ABB robot controllers, machine automation, or marine alarm systems, the MT-91-ARC FP A is a recognizable field item: a German-built, serial-interfaced operator panel that presents machine state and alarm conditions to the operator and returns control inputs to the system — a role that keeps it relevant long after newer touch panels have appeared, because the replacement need is defined by the installed system, not by the age of the display technology.

MT91-ARC MT-91-ARC FP A MT91
Key Features and Advantages
Purpose-built for machine-side operation: The MT-91-ARC FP A is an operator interface in the truest sense — display, alarm indication, and control entry in one panel, positioned where the machine is. Its dual identity in the market (robot operator panel and alarm monitoring display panel) reflects a single engineering strength: the panel presents operating state and alarms clearly enough to be used as an annunciator, and accepts operator input directly enough to serve robot and machine control.
Serial connectivity built for distance and noise: RS-422/485 gives the panel its industrial character — differential serial signaling that tolerates longer cable runs and electrically noisy machine environments far better than a short-hop desktop link, while the V.24/RS-232-C option covers legacy connections. For a panel mounted at a robot cell or on a control console some distance from the controller, this is the difference between a stable link and a nuisance fault.
A low-power, low-heat design: A 24 V DC feed with a nameplate maximum of 60 V / 0.5 A means the panel draws modest power and dissipates little heat, so it can be mounted inside consoles and enclosures without the ventilation burden of a PC-class HMI. In retrofit and marine work, where available panel space and cooling are scarce, this matters more than a specification sheet suggests.
Cleanly identified for procurement: The GATS 11 01 67 R 0401 service identity and hardware article 200010450702 give sourcing and maintenance teams two exact reference keys, eliminating the ambiguity that comes with a panel marketed under several spellings (MT-91-ARC, MT91ARCFPA). A spare can be verified against ABB’s part structure before it reaches the cabinet.
German-built longevity: Manufactured by ABB SST GmbH, the MT-91-ARC FP A belongs to the generation of industrial HMIs engineered for years of continuous service in production environments — the reason these panels still surface regularly in the surplus market as serviceable units, and the reason plants keep them in their installed base rather than re-engineering around them.
Vendor-documented display behavior: Dealers that have inspected working units report a 12.1-inch TFT LCD at 800 × 600 (SVGA) with 262K colors — a display large enough for alarm lists and machine status pages without the cost and fragility of a modern touch panel, which makes the MT-91 a practical, maintainable choice in control rooms and on machine consoles.
Application Areas
The MT-91-ARC FP A serves the operator layer of industrial control systems: on robot cells and automated production lines it is the panel at the station — displaying machine state, alarms, and diagnostics while accepting the operator’s control entries, typically over a serial link to the robot or machine controller. In these roles the panel replaces the need to walk to a central HMI for every status check, keeping operations and fault awareness at the point of use.
In marine and offshore control rooms the same hardware appears as an MT91 alarm monitoring display panel — a dedicated annunciator that keeps watch over alarm conditions from the vessel’s automation system and presents them in a form the watchkeeper can read at a glance. The panel’s 24 V DC supply and RS-422/485 communication align naturally with shipboard power and long serial runs through the vessel, which is why marine electronics dealers carry it as a spares item.
Across these settings the MT-91-ARC FP A covers the machine-adjacent HMI and alarm-annunciation duties that sit between the controller and the operator: live status presentation, alarm reporting, and control input, delivered through a serial-interfaced, low-power, panel-mounted unit that integrates into the existing control architecture rather than requiring a platform change.

Installation and Maintenance
Installation preparation: Before mounting the MT-91-ARC FP A, confirm the panel identity against both reference keys — service part GATS 11 01 67 R 0401 and hardware article 200010450702 — since the model circulates under several spellings and only the identifiers guarantee the correct unit. Verify the cabinet supplies 24 V DC within the nameplate limits (max. 60 V / 0.5 A), and check the serial interface type of the installed unit — RS-422/485 or V.24/RS-232-C — against the controller’s port before wiring, because the two standards use different signal levels and wiring rules. Mount the panel in the console or cabinet cutout with adequate clearance for ventilation and connector access, and route the serial and power cables clear of power conductors.
Maintenance advice: Treat the serial link as the primary suspect in interface faults: check cable, connectors, and wiring terminations before the panel itself, since RS-422/485 installations fail most often at the connector. Keep the display and front membrane clean with a soft, dry cloth, and inspect the panel during routine rounds for damaged connectors or signs of moisture. Store a spare MT-91-ARC FP A in dry, temperature-stable storage, and when replacing a unit, record both the service part ID and hardware article number in the equipment log so the installed panel identity remains traceable for future sourcing.
Product Warranty
The MT-91-ARC FP A is supplied as a tested unit — new, new-surplus, or reconditioned — with warranty covering functional condition, materials, and workmanship, and the panel is verified against the nameplate identity GATS 11 01 67 R 0401 before delivery. Because the panel remains a recognized item in the ABB service-parts structure and in the marine and industrial surplus market, replacements and documentation remain accessible, and technical guidance covers serial wiring, 24 V DC integration, and panel-level fault isolation. For robot cells, machine consoles, and vessel control rooms running the MT91 family, this makes the MT-91-ARC FP A a dependable, traceable spare that keeps the operator interface of the installed system in service.
