Tap Position Transmitter TPT-20

Tap Position Transmitter TPT-20

Masibus Model TPT-20 is a 4 wire Tap Position Transmitter that isolates & converts the resistance input corresponding to the tap position of transformer and the Output is Proportional to tap position of transformer thus providing Visual and Electrical Output of tap position. The analog output can be further connected to RTU, Logger, PLC, Control units etc.

TPT-20 Resistance-type position transmitter accepts the input range of 0-2.5KΩ or 0-25KΩ. A built-in 4 digit Red LED display facilitates the user to monitor the tap position and helps in fast and easy configuration and calibration. Tap number is programmable upto 100 via keypad and tap change-over delay is 1-60 sec field programmable.

Model TPT-20 offers excellent accuracy and stability for reliable operation in hostile environments. TPT-20 has three port Isolation between Input, Output and Power supply.

TPT-20 has optional two relays for alarm purpose along with optional isolated serial communication on RS485 over MODBUS RTU protocol for interfacing with SCADA/PLC, PC based data acquisition and reporting system. So it is used as Transformer Tap Position Transducer with Communication or transformer tap position Transducer with Alarm. Additionally, TPT-20 has upto two completely isolated retransmission outputs wherein 2nd output is optional. It can also be used as a Digital Tap Position Indicator, Tap Position transducer, Digital Tap Position Repeater or Transformer Tap Position Transmitter
