The AI893 analog input module has 8 channels. The module contains intrinsically safe protection components on each channel for connecting process equipment to hazardous areas without the need for additional external equipment.

The module can be configured as a 2-wire or 3-wire RTD sensor or TC sensor. In TC mode, channel 8 is used for cold end (ambient) temperature measurement and thus used as channel 1. CJ channel of 7. The junction temperature can be measured either locally on the MTU screw terminal or on a connection unit far from the device. The cold end temperature is measured using a 3-wire Pt 100 sensor. Alternatively, the user can set the fixed junction temperature of the module (as a parameter). When CJ temperature measurements are not required, channels 8 can be used in the same way as channels 1-7.

The TU890 and TU891 compact Mtus can be used with this module to enable three-wire connections to process equipment without the need for additional terminals. The TU890 is for explosion-proof applications and the TU891 is for non-explosion-proof applications.
