Description
The FieldPoint module with the part number 777318-124 is a specialized device designed for precision temperature measurements. It is identified as model FP-RTD-124 and is characterized as a 4 Wire RTD Input Module, 16 Bit, although it is noted that this model is not intended for new designs. This module is capable of reading temperatures through 8 inputs that accommodate both 2-wire and 4-wire Resistance Temperature Detectors (RTDs).
Each input channel on this module features 4 terminals: a positive sensing input, a negative sensing input, an excitation output, and a common input. This design ensures precise temperature measurements. The module supports RTDs with nominal resistances of 100 Ω or 1000 Ω, compatible with 6 Temperature Coefficient of Resistance (TCR) values, offering flexibility in sensor selection.
Temperature measurement capabilities of this module are extensive, spanning from -200 to 850 °C, 73 to 1,123 K, and -328 to 1,562 °F. With a resolution of 0.016 °C, it ensures high precision in readings. The module updates temperature data at a rate of 1 update/second per channel, ensuring timely and accurate temperature monitoring.
Operating on a mere 35 mW power consumption drawn from a network module, it is an energy-efficient solution for temperature monitoring. Users can choose between data scaling options in resistance (Ω) or temperature units (°C, °F, °K), according to their requirements.
Among its features, the module is hot-swappable, allowing for easy replacement without the need to power down the system. It supports auto configuration for hassle-free setup and features built-in signal conditioning for improved signal quality. Additionally, it is equipped with 50/60 Hz noise rejection filters, enhancing its reliability in environments with electrical noise.
