Detailed data
ABB AI895 3BSC690086R1 Analog Input Module
The AI895 analog input module can directly connect to 2-wire transmitters, and with specific connections, it can also connect to 4-wire transmitters without losing HART functionality. The AI895 analog input module has 8 channels. The module includes intrinsically safe protection components on each channel for connecting process devices in hazardous areas without the need for additional external devices.
Each channel can power and monitor a two-wire process transmitter and HART communication. The input voltage drop for the current input is typically 3 V, including PTC. The transmitter power supply for each channel is capable of providing at least 15 V at 20 mA loop current to power Ex-certified process transmitters, limited to 23 mA in overload conditions.

Frequently asked questions about the product are as follows:
-What is the ABB AI895 3BSC690086R1?
The ABB AI895 3BSC690086R1 is an analog input module that belongs to ABB's System 800xA series of products. It is mainly used to receive analog signals in automation systems and convert them into digital signals for further processing and analysis.
-How many input channels does it have?
The AI895 3BSC690086R1 has 8 differential input channels dedicated to thermocouple/mV measurement.
-What is its measurement range?
Each channel can be configured to measure in a range of -30 mV to +75 mV linear, or the corresponding thermocouple type.
-What are the characteristics of its channel configuration?
One of the channels (channel 8) can be configured for "cold end" (ambient) temperature measurement, so it can be used as a CJ channel of the channel.
