The Freedom Series Distributed Control and Monitoring Unit (DCMU) brings intelligence and advanced capabilities to traditional airfield lighting power and control devices. By adding embedded processors, digital signal processing and redundant communications capabilities, the Freedom Series™ DCMU provides state-of-the art distributed control and monitoring to existing equipment including constant current regulators (CCR), circuit selectors, nonregulated controls, approach systems, generators and transfer systems.

• Provides L827/L829 monitoring plus additional analog and digital monitoring to existing constant current regulators.
• Provides customizable inputs and outputs for any type of device to be controlled or monitored.
• Provides redundant communications, eliminating point to point I/O wiring to a centralized PLC or I/O panel. Standard industrial protocols provide direct communication to Liberty or third-party control systems.
• Provides ability to add additional monitoring and control features in a modular fashion without requiring additional centralized I/O or wiring.
• Provides latching failsafe capabilities ensuring that a control system or DCMU failure will not cause a sudden change in lighting patterns.
• Provides control and monitoring status information on a local display, on a centralized remote annunciator panel or through a control and monitoring system.
• Provides a redundant gateway between Serial (RS485) devices and 100MB Ethernet devices.
