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© provides an 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 a self-contained, NEMA 4X rated model.
