Gems™ Opto-Pak© Controllers convert standard 110 VAV line current to the 12 VDC input power required for many of Gems solid state level switches. These controllers may be used with all Gems electro-optic sensors operating on 12 VDC. Opto-Paks© provide a SPDT, 5 Amp relay output for direct control of moderate loads. Two models are available: an open circuit board version for incorporation into custom enclosures, and self-contained, NEMA 4X model pictured here.
