USB configured 2-wire transmitters

January 2013 Sensors & Transducers

Acromag’s new TT230 series of isolated transmitters are designed to provide easier installation and setup. These signal conditioners are only 12,5 mm wide for high-density mounting on DIN rails and provide a convenient USB connection to a PC for simple, precise configuration using Windows software. A number of models are available to isolate and convert thermocouple, RTD, voltage or current input signals to a 4-20 mA output. These two-wire instruments are loop-powered and support both source or sink output wiring connections on the current loop with a 12-32 VDC supply. A ruggedised design features -40 to 80°C operation, electrical noise immunity and surge protection. CE and UL/cUL Class 1 Division 2 Zone 2 hazardous location approvals are pending.

Each model accommodates a variety of signal types. Thermocouple units accept eight different sensor types (J, K, T, R, S, E, B, N), as well as ±100 mV inputs. RTD units accommodate 2-, 3-, and 4-wire 100 ohm Platinum sensors or 0-900 ohm linear resistance inputs. Voltage models convert bipolar signals from ±10 mV to ±150 VDC with multiple selectable ranges. The current units are widely adjustable to support ±20 mA, 0-20 mA, and 4-20 mA DC input signals.

All models deliver high accuracy, superior noise resistance and fast response times. They also demonstrate excellent linearity and stability with very low temperature drift. Software calibration eliminates zero/span pots, DIP switches, and pushbuttons for easy programming of ranges, over/under scale thresholds, and fail-safe settings. Programmable over/under range and fault/alarm levels enable identification of a runaway process or broken sensor. Selectable up/downscale failsafe modes ensure a safe, predictable shutdown with a NAMUR-compliant fault response.
