Description
The AI845-EA 3BSE023675R2 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.
Applications
Petrochemical plants: HART data acquisition and redundant monitoring of reactor pressure and level transmitters.
Offshore oil production facilities (platforms): Safety monitoring of critical oil and gas pipelines in harsh environments.
Natural gas processing plants: Precision signal processing for gas booster stations and desulfurization processes.
Fine chemical production plants: High-value feedstock proportioning control and process safety instrumented systems (SIS).
Nuclear power plants: Redundant parameter acquisition and equipment status diagnostics for auxiliary systems.
Pharmaceutical distillation plants: HART smart instrument integration in high-purity extraction processes.
Features and benefits
8 channels for 0...20 mA, 4...20 mA, 0...5 V or 1...5 V d.c., single ended unipolar inputs

2 Supervision:
Module error: analog read back, reference voltage, internal power supply, checksum, watchdog and memory error
Internal channel error: low pass filter´, multiplexer, test channel error
External channel error: external power supply low, transmitter power, external shunt error
3 Status indication of supervision :Module Error, Module Warning, Channel error
FAQ
Q: What is the AI845-EA 3BSE023675R2?
A: It is a Analog Input Module.
Q: What is the difference between AI845-EA and AI845?
A: AI845-EA (with the -EA suffix) is a version optimized for Essential Automation systems. It is functionally and performance-wise essentially the same as the standard AI845, but is better suited for specific system architectures or project configurations. In practice, they are often interchangeable, but confirmation is needed based on the system version and project configuration.
Q: Does AI845-EA 3BSE023675R2 support hot-swap?
A: Yes. As a member of the S800 I/O series, this module supports hot-swap functionality, allowing module replacement without power interruption. However, in non-redundant configurations, it is recommended to verify the system's safety status and interlocking conditions before operation to avoid impacting process control.
Q: How to Check Price and Availability for AI845-EA 3BSE023675R2?
