Description
The FieldPoint module described by part numbers 185078E-01L / 777518-122 is identified as model FP-RTD-122. This module is an RTD Input Module featuring an 8-channel configuration, specifically designed for 16-bit resolution but is not recommended for new designs. It operates with a 3-wire configuration and is equipped with a 0.25 mA stable current source for sensor excitation.
The module offers flexibility in measurement scaling, allowing for temperature units in Celsius (°C), Fahrenheit (°F), or Kelvin (°K), as well as resistance measurements. Its input characteristics include a delta-sigma ADC and filters for 50/60 Hz rejection, ensuring accurate readings across a wide range of environmental conditions.
It supports RTD types of 100 and 1,000 Ω platinum, offering resistance measurement ranges of 400 Ω and 4000 Ω. With the capacity to handle 8 inputs and providing an excitation current of 0.25 mA per channel, this module is designed to cater to a variety of measurement needs. Additionally, it features optical bank isolation for enhanced safety and reliability.
For ease of monitoring, the module is equipped with two green LEDs indicating POWER and READY status, providing users with immediate visual feedback on the operational state of the module.
