DPM8001T

Quantity:  
8 Digit process TOTALISER/INTEGRATOR (Rate display 5½-digit) (4 - 20mA)

These high accuracy, high quality LED indicators are used for universal process, counting and frequency applications. The -T option includes process integration / totalisation function. These indicators can be applied to most process variables with analogue & digital inputs, such as the measurement & display of pressure, level, flow, frequency, DC voltages or currents & revolutions per minute. Options include linearisation, analogue output and set-points up to a total of four.
  • 24Vdc supply for 2 / 3 wire transmitters
  • Process inputs, frequency & counting functions
  • Process x frequency for kW, mass flow applications etc.
  • Keypad lockout standard to prevent authorised access to programming menu
