AI843 热电偶/mV 输入模块提供 8 个差分输入通道,用于热电偶/mV 测量。每个通道可配置的测量范围为:-30 mV 至 +75 mV 线性,或 TC 类型 B、C、E、J、K、L、N、R、S、T 和 U。一个单独的 Pt100 通道用于“冷端”(环境)温度测量,因此用作 Ch. 1...8 的 CJ 通道。
结温可以在 MTU 螺丝端子上本地测量,也可以在远离设备的连接单元上测量。或者,模块的固定结温可以由用户设置(作为参数)或由应用程序设置结温。

The AI843 Thermocouple /mV input module provides 8 differential input channels for thermocouple /mV measurements. Each channel can be configured for measurement ranges from -30 mV to +75 mV linear, or TC types B, C, E, J, K, L, N, R, S, T, and U. A separate Pt100 channel is used for "cold end" (ambient) temperature measurement and is therefore used as Ch.1... CJ channel of 8.
The junction temperature can be measured either locally on the MTU screw terminal or on a connection unit far from the device. Alternatively, the fixed junction temperature of the module can be set by the user (as a parameter) or by the application.
Characteristics and advantages
8 differential input channels for thermocouple /mV
Single or redundant operation
A separate channel used as a CJ channel (4-wire Pt100 RTD)
Various thermocouples having the following characteristics: B, C, E, J, K, L, N, R, S, T, and U
16-bit resolution (A/D converter)
The input is monitored to prevent disconnection
