Model 1511-LTC

The INCON Model 1511-LTC programmable process monitor is a sophisticated microprocessor-based panel instrument.

Applications

  • The INCON Model 1511-LTC is ideal for use in applications that require accurate position measurement.
  • Indicates tap position for load tap changers on transformers utilizing slidewire (resistive) transmitters
  • Provides flexible, real-time, outputs to interface with SCADA, PLCs, and computers
  • Provides visual and electrical indication of changes in tap position
  • Performs absolute position feedback by providing positive confirmation that the LTC has moved to the required tap position as directed
  • Programmable for uni-polar (0 to 32 taps) or bi-polar (-16 to +16 taps) applications

The Model 1511-LTC indicates the position of transformer load tap changers and can be used to perform a number of functions to help improve system operation.

  • Analog output is unaffected by noisy or intermittent input signals
  • Accepts a 0-24 VDC signal from a slidewire (resistive) transmitter
  • Provides regulated 24 VDC slidewire power
  • Mathematically averages 1000 input signal samples to accurately determine the actual input signal value
  • Provides programmable segmented position indication
  • Offers programmable limit outputs for alarm and control (optional)

Features

  • Interfaces LTC position information to SCADA systems
  • Extremely accurate signal conditioner
  • Analog and/or digital output
  • Large five-digit LED display
  • Hard-wired security/ lockout feature
  • Non-volatile storage of program parameters
  • Easy, menu-driven, set up mode through its front panel
