Universal Control Card


The Universal Control Card (UCC) provides multiple control input options using a single control card. Designed for use exclusively with the Envirco family of MAC 10 LEDC and MAC 10 IQ Fan Filter Units, the UCC can be configured for local, remote, or Building Management System control. Cleanroom facility requirements can change as facilities expand or new processes and equipment are brought in. The UCC is fully compatible with all Envirco Control Console Systems and provides the flexibility to add or remove control options without the need to replace existing components. The UCC provides three control options for the FFU; local manual control via the built in potentiometer, remote or wall mount speed control via 0-10V analog signal, and networked system control via MODBUS compatible RTU Network Protocol. The UCC is factory installed in the electrical enclosure of the FFU, eliminating the need for additional or external DC power sources.
