SchUP120U is subsequent development of  series-produced SchUP120 indicator. It is installed on the control panel and structurally compatible with the standard pointer quotient-meter of UP30 type.
The indicator is suitable for installation on Bulgaria drives MZ-2, MZ-4 instead of stages indicator of LKM type, on Germany drives MR, EM and ED-S, as well as on any other drives with the resistive pickup or the pickup with an output signal “current loop”. The indicator operates in combination with the selsyn transmitter of drive turn angle type BD404 or BD1404 and suitable for installation on all drives (types RNT 13, PDP-1, PDP-4, etc.).
SchUP120U is provided with setting maximum permissible drive positions. Presence of digital and analogue output signals allows transmitting data on a drive stage to telemechanics systems, ADCS, SSE (stepped start equipment).
