Industrial SAC-M1890-S1ND Programmable Indicator

Autotech Controls SAC-M1890-S1ND Programmable Indicator is a refurbished readout module in the M1890-S family, designed to accompany the Programmable Position Transducer (M1890-S) and a Selsyn (synchro) position system. As the indicator portion of Autotech’s Selsyn-based position sensing lineup, the SAC-M1890-S1ND displays angular position information generated by a compatible transducer or resolver, enabling local or remote readouts in industrial automation or motion-control panels. The M1890-S family is described as a Programmable Position Transducer and Selsyn Indicator, and the SAC-M1890-S1ND variant is commonly sold by distributors as a refurbished unit under the SAC-M1890-S1ND part number, with related models in the line offering similar readout capabilities for legacy or retrofit installations. Typical applications include machine control panels and position feedback loops where precise indication of shaft angle is required through a Selsyn/resolver ecosystem.
