Acromag Releases New Isolated Transmitters

October 11, 2012

The USB-configured 2-wire transmitters feature universal sink/source 4–20 mA output for easy installation and are PC/Windows-programmable.

WIXOM, MI /PRNewswire/ -- The new TT230 series of isolated transmitters release by Acromag 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 4–20mA 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 ruggedized design features –40°C 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.

"The Acromag TT230 Series represents the latest innovations and state-of-the-art advancements in signal conditioning technology. Our two most exciting innovations include simple USB configuration and a universal sink/ source 4–20 mA output to accommodate virtually any process measurement/control application. All units support both 4–20 mA sinking (2-wire) and sourcing output (3-wire) device wiring to eliminate confusing model selection," explained Don Lupo, Process Group Sales and Marketing Director.

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 plus or minus 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 plus or minus 10 mV to plus or minus 150 VDC with multiple selectable ranges. The current units are widely adjustable to support plus or minus 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.

Many other features add greater flexibility. 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.
