Technical Specifications
| Brand | ABB |
|---|---|
| Model | 3BDH000050R1 |
| Category | Industrial Automation |
| Full Official Name | ABB AM 811F Battery Module, Order Code 3BDH000050R1ABB Group |
| Core Function | Dedicated backup battery slot module for ABB Freelance AC 800F process controllers. Installs into an empty E2 slot of the AC 800F base unit to hold SB 808F lithium backup batteries (batteries sold separately). It maintains CPU program, parameter, and configuration data during complete mains power loss, preventing controller data corruption or full reset. Mandatory software compatibility: AC 800F firmware V7.1SP2a or higher. Designed exclusively for pairing with PM 802F / PM 803F processor modulesABB Group. |
| Main Control System | ABB Freelance AC 800F Distributed Process Control System (DCS) |
| Matching Processor Modules | PM 802F, PM 803F CPU controllers |
| Base Unit Hardware | Standard AC 800F rack backplanes with spare E2 expansion slots |
| Supported Industrial Applications | Oil & gas processing, water/wastewater treatment, chemical manufacturing, pulp & paper plant automation, power plant auxiliary control |
| Required Accessory | SB 808F backup lithium battery (must be purchased separately for operation) |
| Depth | 125 mm, Height: 155 mm, Width: 28 mm (single narrow E2 slot width) |
| Data Loss On Power Failure | Caused by expired SB 808F batteries, loose battery socket contacts on AM811F PCB, or broken internal battery wiring traces. |
| Battery Drain Shortage | Internal PCB diode/transistor component failure creating parasitic current draw, draining SB808F batteries within weeks instead of standard 2–3 year lifespan. |
| Firmware Mismatch Error | System diagnostic alarms triggered if controller software is below mandatory V7.1SP2a revision. |
| Direct OEM Equivalent (Same Part) | 3BDH000050R1 (AM 811F) – no revised superseding ABB factory part number; this is the sole official battery module for AC 800F E2 slots. |
| System Architecture Alternative | AM 810F integrated battery processor module (combines CPU + battery backup in one slot; replaces separate PM80xF + AM811F two-slot setup) |
| System Upgrade Alternative | Migrate to AC 800M controller series with integrated on-board backup battery slots (eliminates need for separate AM811F modules entirely) |
| Mounting | rack mount |
| Origin | Germany / Original |
| Condition | New Original Factory Sealed |
| Warranty | 12 Months |
| Shipping | Global Delivery via DHL/FedEx/UPS |
