ABB AI845 3BSE023675R1 Analog Input Module
Overview
ABB AI845 3BSE023675R1 Analog Input Module for single or redundant applications. The module has 8 channels. Each channel can be either a voltage or current input when MTU TU844 or TU845 is used, when other MTUs are used all channels become voltage or current inputs.
The voltage and current input is able to withstand an overvoltage or undervoltage of at least 11 V d.c. The input resistance for voltage input is greater than 10 M ohm and the input resistance for current input is 250 ohm.
The module distributes the external HART compatible transmitter supply to each channel. This adds a simple connection to distribute the supply to 2-wire or 3-wire transmitters. The transmitter power is supervised and current limited.
🚀Function & Features
- 8-Channel Analog Inputs: AI845 current: 0 ... 20 mA or 4 ... 20 mA. Voltage: 0 ... 5 V or 1 ... 5 V. Single-ended, unipolar inputs for signal processing.
- Single or redundant operation: AI845 can be configured for single or redundant operation.
- Isolation: AI845 isolates each of 8 channels from ground, ensuring noise immunity and signal integrity.
- Current-limited transmitter power supply: Each channel of AI845 includes a current-limited transmitter power supply to protect connected field devices from overcurrent.
