A meter relay in which the mechanical contacts on the meter of a mechanically operating type of relay are replaced by solid state circuitry. The circuitry is readily adjustable by a simple potentiometer of rheostat to operate an indicating signal and/or a control for industrial apparatus or the like at any desired point over the entire range of a meter. The circuitry is operative, however with or without a meter. A plurality of identical circuits mounted on separate panels or modular units may be ganged to operate different indicators and/or controls at a plurality of points over the range of one or more relay meter devices.
