Franklin 1250B-4-M Programmable Position Monitor
The Franklin Electric INCON 1250B-4-M Position Indicator is an advanced instrument engineered for precise measurement of absolute local and remote transformer load tap changer (LTC) positions. Designed for use with synchro transmitters, this monitor is an integral component for balancing transformer loads, regulating line voltage, and reducing overall power costs across power grid operations.
Equipped with a highly visible 5-digit LED display, this programmable monitor can define and track up to 100 specific position segments. It features both a 4-20 mA analog output and an RS-485 serial port for multi-drop communication capabilities. The 1250B-4-M also offers the specialized capability to convert rotational position into a non-linear indication, making it highly adaptable for complex monitoring applications such as hydro dam gate positioning.
