Avtron K663C20438 Analog Converter

Avtron K663C20438 Analog Converter is a two-input, three-output analog signal converter module in the K663 family, designed to integrate with Avtron tachometer and drive systems. Channel 1 accepts current sensing from a shunt or current transformer, or a +/-10 VDC signal; Channel 2 handles armature voltage input up to +/-750 VDC. Its three outputs include a pair of +/-10 VDC lines for armature voltage and armature current, plus a 0–10 kHz quadrature output for current, enabling synchronized speed and torque feedback in control loops. The unit is powered from a standard 115/230 VAC supply, with armature input ranges specified as 250–750 VDC, making it suitable for mid- to high-voltage installations. The K663C20438 SKU is a specific Avtron catalog variant and is commonly referenced in distributor catalogs and repair inventories. As of current manufacturer determinations, the part is listed as discontinued, with remaining stock typically handled by specialist distributors or refurbishment providers and weights around 4.8 lb. This module is part of Avtron’s legacy analog conversion solutions, used to translate high-voltage motor signals into standardized analog outputs for drive controls and tachometer systems.
