虽然默认情况下所有通道都使能，但可以禁用未使用的通道，以提高扫描通道的采样速率。每个通道中的硬件低通滤波可抑制50和60Hz线路频率。高、低、高-高和低-低警报提供基本的监控和警告功能，以确保最佳的工艺流程和故障安全应用。精密、低幅度电流源可最大限度地降低传感器自热，并消除引线电阻误差。

输入传感器和输入范围可按每个通道选择，根据传感器的不同，有一到三个范围可供选择。允许超出规定输入值2%的超量程和欠量程。传感器线性化在模块中进行，精度保证到f.s .现场I/O连接通过可插拔接线板进行，其位置指定为接线屏蔽的终端。输入至总线隔离是一种鲁棒的1500Vrms。MAQ20-RTD31的主要特性能够为传感器、范围、报警限值和平均值单独配置通道，确保系统能够满足最苛刻的应用。
NAMU-01C
ABB NAMU-01C selectively enables module channels for scanning data before releasing the maq 20 RTD/potentiometer module. MAQ20-RTD31 can interface with three types of three wire sensors: 100 ω Pt and 120 ω Ni RTD and a potentiometer up to 5k. This module has 6 input channels, each with a continuous overload protection of up to 240Vrms to prevent accidental wiring errors. To ensure data integrity, overloaded channels will not have adverse effects on other channels in the module. Transient protection complies with the ANSI/IEEE C37.90.1 standard.

Although all channels are enabled by default, unused channels can be disabled to increase the sampling rate of scanning channels. The hardware low-pass filtering in each channel can suppress line frequencies of 50 and 60Hz. High, low, high high, and low low alarms provide basic monitoring and warning functions to ensure optimal process flow and fail safe applications. A precise, low amplitude current source can minimize sensor self heating and eliminate lead resistance errors to the greatest extent possible.

The input sensor and input range can be selected according to each channel, and there are one to three ranges to choose from depending on the sensor. Allow for over range and under range exceeding the specified input value by 2%. Sensor linearization is carried out within the module, ensuring accuracy up to f. s. The field I/O connection is made through a pluggable terminal block, which is designated as the terminal of the wiring shield. Input to bus isolation is a robust 1500Vrms. The main feature of MAQ20-RTD31 is the ability to configure separate channels for sensors, ranges, alarm limits, and averages, ensuring that the system can meet the most demanding applications.
