These models convert sensor inputs to proportional process current or voltage output signals. Excellent accuracy and stability ensure reliable measurements in harsh industrial environments. 3-way isolation. Input, output, and power circuits are isolated from each other. 250T: Loop-powered transmitter series 350T: DC-powered transmitter series 450T: AC-powered transmitter series","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 ±0.25 mV, whichever is greater. Includes repeatability, hysteresis, terminal point linearity, and adjustment resolution.","Ambient Temperature Effect -RBPx: ±0.01% of output span per °F (±0.018% \/ °C). -RBCx: ±0.025% of output span per °F (±0.045% \/ °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: 120dB at 60Hz, 100 ohm unbalance. Normal Mode: 26dB at 60Hz, 100 ohm source, 20dB at 60Hz, 10 ohm source.","Response Time Output reaches 98% of output span in 350mS.","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.
