About The ABB TEU471-EX.A Temperature Transmitter

The TEU471-EX.A temperature transmitter is equipped with a local communication interface (LKS) for workshop parameterization, and its power supply is provided by a PC; it also supports frequency shift keying (FSK) for remote parameterization and bus operation. The data format follows the HART protocol. The device provides a variety of power supply options, including 24 V UC, 115 V AC and 230 V AC (switchable to 24 V UC), an AC voltage range of -15% to +10%, a frequency of 48 to 62 Hz, a DC voltage of 18 to 33 V, and a residual ripple of no more than 20% within the tolerance range. The power consumption is approximately 1.2 W and 1.5 VA for 24 V UC, approximately 2 W and 5 VA for 115 V AC, and approximately 2 W and 8 VA for 230 V AC. Under rated conditions (according to IEC 770), the measurement deviation (relative to the set measuring range) is 0.1% × MV + 0.1% + K1, the additional error of the internal reference junction is 0.25 K, the additional error when using MK 44, MK 45 is 0.1% × MV, the consistency error (included in the measurement deviation) is 0.1% + K2.
