ORBIT AL-7108-CCU | Central Communication Control Unit

Product Overview

The ORBIT AL-7108-CCU is a Central Communication Control Unit designed for communication and control applications within Orbit system architectures. The unit is identified by part number L00120004 and is configured as a Central Control Unit with dual LAN connectivity. Available documentation and marketplace specifications identify 115/230 VAC input, 50/60 Hz operation, and Windows CE Pro 5.0.

The dual-LAN configuration makes this unit suitable for systems where communication between multiple controllers, terminals, or networked equipment needs to be coordinated through a central control platform. Its Windows CE Pro 5.0 environment also indicates an embedded-computing design rather than a conventional standalone PLC I/O module.

This model is particularly useful when maintaining an existing Orbit installation where the original communication/control hardware is no longer readily available. Before replacement, the part number, hardware version, connectors, software environment, and system configuration should be compared with the installed unit.

The 115/230 VAC, 6/3 A and 50/60 Hz specifications are consistently shown in multiple current listings for this exact part number.

Typical Applications

The AL-7108-CCU can be considered for:

Industrial communication and control systems
Centralized equipment management
Marine and offshore automation systems
Building or facility control architectures
Legacy Orbit control installations
Replacement of failed or aging communication control units
System spare-parts inventory for existing Orbit equipment

The exact application should be confirmed against the original system documentation because the publicly available information does not provide a complete interface or protocol specification.

Installation & Configuration

Before installation, compare the replacement unit with the existing controller using the complete part number and hardware markings.

Isolate the incoming 115/230 VAC supply before removing the existing unit.
Record all network and control wiring before disconnection.
Verify the installed unit’s AL-7108-CCU and L00120004 markings.
Confirm the required AC input voltage and frequency.
Check LAN connections and network addressing before startup.
Verify that the required Windows CE Pro 5.0-based application or system software is available.
Power up the unit under controlled conditions.
Confirm network communication with connected equipment.
Check system alarms, communication status, and operator functions before returning the system to service.

Do not assume that a visually similar Orbit controller is a direct replacement. The software version, hardware revision, LAN configuration, and system-specific programming can affect interchangeability.

Maintenance & Inspection

For a spare or replacement AL-7108-CCU, inspect the unit before installation:

Check the enclosure for impact or corrosion.
Inspect connectors for bent or oxidized contacts.
Check LAN ports and cable connections.
Inspect the AC input section for loose terminals or heat damage.
Verify the nameplate and part number.
Confirm the software/firmware information where accessible.
Check cooling paths and remove accumulated dust.
Record the hardware revision and serial information for future maintenance.

For equipment that has been stored for a long period, a controlled power-up and communication test is recommended before putting it into an operating system.

Replacement Notes

The complete identification for this unit is:

ORBIT AL-7108-CCU — L00120004

Related descriptions found in current listings include “Central Communication Control Unit,” “Central Control Unit Dual LAN,” and “Communication Control Unit.” These descriptions refer to the same AL-7108-CCU/L00120004 configuration.

When sourcing a replacement, match the complete part number rather than relying only on the AL-7108-CCU model designation.
