FOR SALE: Industrial Control Unit FXM/FX/FXL – Model FXL/NO – Multi-I/O Modular Controller System – 230V RS485 – For Automation, Access Control, Alarms

Overview:
This is a modular industrial automation controller system, based on the FXM / FX / FXL platform. The unit is clearly marked as FXL/NO, and appears to be a custom-configured logic and I/O controller, likely built for use in access control, industrial safety systems, elevator logic, or building automation infrastructure.

This unit features multiple modular I/O and communication boards, heavy-duty industrial connectors, and a large toroidal transformer for integrated power regulation.

While specific manufacturer details are not listed on the outside, the component architecture, markings (eg, FXMC, FXAL08SW110, RS485 SYSTEM 1/2), and build quality suggest this was built in Scandinavia (likely Norway) for commercial/industrial-grade deployments between 2005–2010.

Included Components:
• Main chassis and metal housing (rack-mountable, industrial enclosure)
• Toroidal transformer (230V AC, approx. 700mA, integrated internal power)
• 3x main logic boards:
• FXMC/SW110
• FXAL08SW110
• Likely CPU/control and I/O interfaces
• 6x XIO relay/protection loop boards:
• Marked: “XIO PRO 3.3V / 5V LOOP”
• Labeled 1 through 6
• Connected to main boards via internal pin headers
• Used for fail-safe monitoring, access control doors, sensor loops
• RS-485 System Interface (labelled “RS485 SYSTEM 1” and “RS485 SYSTEM 2”)
• 24V battery backup terminal
• Factory label:
• Type: FXM / FX / FXL
• Model: FXL/NO
• Serial No: 20072585374
• Current draw: 2.2–4.5A (system), 700mA (PWR)
• Verified by QA inspector “MIK” and “HVT”

What this system is likely used for:

This system is clearly part of a larger industrial or municipal control infrastructure. Based on architecture and features, it likely belongs to one of the following use cases:
• Access Control System (eg, controlled doors in secure buildings, prisons, labs)
• Elevator and Lift Control Systems (logic and safety relay coordination)
• Building Management Systems (BMS) (HVAC, lighting, fire override)
• Alarm and Safety Loop Monitoring
• Industrial Automation / PLC I/O Extensions
• Municipal emergency systems or transport infrastructure
• Bank vault / airlock logic
• Legacy security system hubs (2000s era)

Compatibility and Integration:
While the specific manufacturer is not confirmed, this system appears to be compatible or analogous with platforms from:
• Siemens
• ABB
• Schneider Electric / TAC / Satchwell
• Honeywell
• Kongsberg Gruppen
• Eltek / Autronica
• Norwegian/Scandinavian defense & access control integrators
Uses RS-485 serial interface, compatible with most industrial BMS, MODBUS, or custom supervisory systems.

Estimated production period:
• Manufactured: Mid-2000s (likely 2007 based on serial format)
• Still in use in many long-term infrastructure installations
• Typical lifetime of such equipment: 15–25 years, often extended with spare parts

Condition:
• Sold as-is, untested.
• No visible physical damage.
• Assumed functional when removed from service.
• Includes original wiring, connectors, and configuration labels (as found in situ).

Price: NOK 2,000 (Approx. €170 / $180)
Price is firm — these modules are rare and may be valuable to the right engineer or facility operator.

Ideal for:
• Engineers maintaining legacy security or automation systems
• Municipalities or infrastructure operators needing compatible spare parts
