ABB PM783F 3BDH000364R0002 – Controller CPU for Freelance (AC 800F) Systems

• Warranty: 365 days

• Delivery time: 1 week for in-stock items; no more than 1 month at the latest

• Payment: 50% advance payment; full payment before delivery

• Express options: FedEx, UPS, DHL

• Freelance/AC 800F controller CPU – Designed for ABB’s Freelance DCS, with smooth engineering in Control Builder F.

• Fieldbus-focused architecture – In many cases, the PM783F is used with PROFIBUS DP, Modbus TCP/RTU, and FOUNDATION Fieldbus (via linking devices) to cover DI/DO/AI/AO needs.

• Stable 24 VDC operation – Industrial 24 VDC supply helps keep panels compact and maintenance simple.

• Redundancy-ready design – Supports controller redundancy configurations for higher availability where the process can’t stop.

• Integrated diagnostics – You might notice faster fault localization thanks to status LEDs, system logs, and engineering tool diagnostics.

• Open communications – Ethernet-based system access and serial connectivity for legacy equipment are typically available.

The PM783F is commonly deployed in process industries where fieldbus-centric architectures make sense:

• Water and wastewater plants modernizing legacy PROFIBUS networks

• Oil & gas skids and pipelines needing Modbus TCP/RTU integration

• Chemical and pharmaceuticals with distributed FF/DP I/O islands

• Metals, mining, and power balance-of-plant where redundancy matters

• Pulp & paper and F&B lines requiring quick diagnostics and stable uptime

• Reliability – Stable 24 VDC controller with mature firmware; redundancy options for critical services.

• Compatibility – Works well with existing fieldbus I/O. You typically won’t have to rip and replace your remote I/O islands.

• Lifecycle cost – Simple commissioning and diagnostics reduce engineering hours and site visits over time.

• Support – Documentation and service ecosystem for Freelance/AC 800F is widely available, which usually shortens troubleshooting cycles.

A maintenance supervisor told us their team “swapped to PM783F on a shutdown weekend and kept the same DP segments—startup was smoother than expected.” That’s typical when the fieldbus design is already in good shape.

• Panel & environment – Install in a ventilated control cabinet. Keep within ambient limits (commonly 0–55 °C) and avoid condensation.

• Power & grounding – Use a regulated 24 VDC supply with proper earthing. Separate power and signal wiring; twist and shield fieldbus lines per ABB guidelines.

• Network – For redundancy or segmented networks, consider managed industrial switches and ring or star topologies as recommended.

• Maintenance – Periodically back up the controller project, check event logs, clean dust from vents, and review firmware release notes before updates.

• Spare parts – Keep a spare PM783F and critical interface modules if your process cannot tolerate downtime.

• CE compliant; RoHS/REACH conformity is expected for ABB industrial controllers

• UL/cUL certifications are common for this product class (check the specific marking on the unit or datasheet)

• Manufacturer quality management under ISO standards

• Our warranty: 365 days; ABB factory warranty may vary by region and supply route

• 24 VDC industrial power supply with sufficient headroom and buffering

• Managed industrial Ethernet switch (for controller and engineering network)

• PROFIBUS DP cabling and terminators; FOUNDATION Fieldbus linking device when FF H1 is needed

• Surge protection and proper grounding kits to improve EMC resilience

Note: Interface availability and exact mechanical details can vary slightly by hardware revision. If you share your existing network topology and firmware level, we can cross-check the PM783F build against your system for a neat, low-risk drop-in.
