These transmitters accept periodic or pulse waveform signals such as those originating from tachometers, magnetic transducers, and turbine flow meters, and provide a proportional process current or voltage output signal.

Models

250T: Loop-powered transmitter series
350T: DC-powered transmitter series
450T: AC-powered transmitter series

Storage: -40 to 185°F (-40 to 85°C)
Accuracy:
±0.1% of calibrated span. Includes repeat-ability, hysteresis, terminal point linearity, and adjustment resolution.
Ambient Temperature Effect:
Less than ±0.01% of output span per °F (±0.018% per °C)
(Specification includes the combined effects of zero and span over temperature)
Noise Resistance:
RFI: Less than ±0.5% ,of output span effect
EMI: Less than ±0.25% of output span effect
Noise Rejection:
Common Mode: 115dB at 60Hz, 100 ohm unbalance
Normal Mode: Not Applicable
Response Time:
Time for output to reach 98% of output span depends on jumper-selectable frequency range.

250T: RLOAD (max.) = (VSUPPLY – 12V) / 20mA
350T: RLOAD (max.) = (VSUPPLY – 2.5V) / 20mA
450T: RLOAD = 600 ohms

  • Excellent accuracy and stability ensure reliable measurements in harsh industrial environments
  • RFI and EMI resistance minimize the effects of environmental noise
  • 90% span adjustment enables precise application calibration
  • Quartz crystal time-base design improves temperature performance
  • Field-selectable time constants optimize output response time and ripple characteristics
  • Selectable threshold circuits accept uni-polar/bipolar inputs (0V bipolar, 1.5V unipolar)
  • Excitation/pull-up circuit adds flexibility
  • 1500V AC peak isolation (250V AC or 354V DC continuous) prevents ground loops
    • 250T models: Input isolated from output/power
    • 350T models: Input isolated from output and power. Output and power share a common
    • 450T models: 3-way isolation. Input, output, and power circuits are isolated from each other
  • Operating temperature range: -13 to 185°F (-25 to 85°C)
