Acromag TT230 series isolated transmitters

Thursday, 31 January, 2013 | Supplied by: Metromatics Pty Ltd


Acromag’s 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.

All units support both 4-20 mA sinking (2-wire) and sourcing output (3-wire) device wiring to eliminate confusing model selection. 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 Ω platinum sensors or 0-900 Ω 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 and noise resistance, and fast response times. They also demonstrate high linearity and stability with very low temperature drift. Software calibration eliminates zero/span pots, DIP switches and push-buttons for easy programming of ranges, over/under-scale thresholds and fail-safe settings.
