Acromag: Process Transmitters Add Temperature and Resistance Measurement Options

这些孤立的信号条件ers support RTD/resistance and potentiometer/thermistor input signals and feature high-density mounting on DIN rails,. With a USB connection to a PC, precise configuration using Windows software is simple. Wiring terminals are front-facing and removable for easy connections and maintenance. Each model accommodates a variety of signal types selected in the configuration software. The TT234 and TT334 interface 100-100 kO via potentiometer/slidewire or 100-1 MO from a thermistor/rheostat. The TT235 and TT335 accept 100 O, 200 O, 500 O, or 1000 O platinum RTD; 120 O nickel RTD; 10 O copper RTD; or 0-450 O linear resistance inputs. Output is ±20 mA, 0-20 mA, or 4-20 mA. The TT330 series also allows for ±10V, ±5 V, 0-5 V, and 0-10 V. The software allows input scaling as well as testing/calibration. TT230 process signal converters have the option of loop-power with a 2-wire connection, or DC-powered with a 3-wire connection. TT330 process signal converters are DC-powered (12-32 V) and support a bussed rail power option for primary or redundant power.
