About Link Electronics 818 OP

Are you in search of a durable, high-quality, and efficient auto-switching module for your subcarrier rack card Look no further than the 818 OP Auto Switch for Subcarrier Rack Card by Link Electronics. This reliable and user-friendly device is meticulously engineered to offer backup reliability in a compact, economical package, making it an ideal choice for professionals in the audio and video production field.

The 818-OP/SC's advanced modular design, when inserted into the PCO-818 frame, offers unprecedented flexibility in an Automatic Changeover unit. This design allows for seamless integration with its sync generator companion, the SPG-812, enabling the PCO-818 frame to deliver top-tier performance and reliability.

The primary function of the 818-OP/SC is to diligently monitor your installation's analog subcarrier signal. In the event of a failure, it automatically switches to a backup analog subcarrier signal, ensuring uninterrupted operation. This modular design offers several advantages over traditional automatic changeover units, including the ability to monitor only the signals used by your system, eliminating the need for unnecessary monitoring capabilities.

The 818-OP/SC is designed for adaptability. Install only the modules you need now and add more as your requirements grow. The shared common chassis between the PCO-818 frame and the SPG-812 frame allows for easy interchangeability of modules and the ability to mix analog and digital signal monitoring within the same chassis.

One of the standout features of the 818-OP/SC is its resilience in the face of power failures. Its design ensures that AC mains failure will not erase the memory of its last generator selection, and a dual-coil latching relay provides a reliable signal path even if power is lost. Moreover, its power supply boasts a universal voltage input range of 85VAC to 260VAC, making it the last unit to shut down in extreme conditions.

The 818-OP/SC also features bi-color LEDs for instant status indication for each signal in your system. If a signal is not in use, the LED can be easily de-selected to avoid false failure indications. A Manual/Automatic switch allows you to override the automatic changeover function and select either generator in the system.

As your system evolves and new technology emerges, the PCO-818 series of modules, including the 818-OP/SC, stands ready to grow with you, promising years of reliable service. Trust in the quality and reliability of Link Electronics for your professional audio and video equipment needs.
