DESCRIPTION: The HI-Q116 was specifically designed to replace (form & fit) the old electromechanical T.A. Bailey's "RY" and Dixson's BG101/202P with 21st Century Technology exclusive to OTEK, the originator of the Automatic Tricolor Bargraph P.I.C. (Programmable Intelligent Controllers). The only similarity is the panel cut out, mounting (rack) and bezel, (same edge connector on request) the rest is all OTEK's proven design with thousands of units installed from Outerspace (MIR & I.S.S. Stations) to Military, Petrochemical, Pharmaceutical, Transportation and other critical industries (all products are LIFETIME WARRANTEED (LTD).)
