Performance Specifications

Input Ranges

Output Ranges
DC Current: 4 to 20mA.
DC voltage: 0 to 5V or 0 to 10V.

Power Requirements

350T: DC Voltage Source
Output Range                Power
4 to 20mA               10 to 36V DC @ 30mA
0 to 5V                      10 to 36V DC @ 9mA

450T: 115V or 230V AC, ±10%, 50 to 60Hz
Output Range                 Power
4 to 20mA                  115V AC @ 0.050A
4 to 20mA                  230V AC @ 0.025A
0 to 5V, 0 to 10V       115V AC @ 0.020A
0 to 5V, 0 to 10V      230V AC @ 0.010A

Ambient Temperature Range:
Operating: -13 to 185°F (-25 to 85°C).
Storage: -40 to 185°F (-40 to 85°C).

Accuracy: ±0.1% of calibrated span or ±0.01mV, whichever is greater. 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).
±0.025% of output span per °F (±0.045% per °C) for narrow span units.
(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: 130dB at 60Hz, 100 ohm unbalance.
Normal Mode: 30dB at 60Hz, 100 ohm source.

Response Time: Output reaches 98% of output span in 300mS.

Bandwidth: -3dB at 3 Hz, typical.

Output Compliance
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
  • 1500V AC peak isolation (250V AC or 354V DC continuous) prevents ground loops
  • Compact, 1-inch wide housing uses less space for easier installation in control panels
  • Low power consumption. 350T units operate on currents as low as 9mA to help prevent expensive upgrades to larger power supplies
