Here are some key features of the 2085-IF4 module:

Input Channels: The module has a total of four input channels. Each channel can be configured as either a digital or analog input, providing flexibility in connecting different types of devices.

Input Types: The module supports a wide range of input types, including voltage, current, thermocouple, and resistance temperature detectors (RTDs). This allows it to interface with various types of sensors and measurement devices.

Signal Resolution: The module offers high-resolution analog inputs, typically ranging from 16 to 20 bits, depending on the specific configuration. This enables accurate and precise measurement of analog signals.

Isolation: The 2085-IF4 module provides electrical isolation between the input channels and the control system. This helps prevent noise and interference from affecting the signal integrity and ensures reliable data acquisition.

Communication: The module communicates with the PLC over a backplane connection using the Ethernet/IP protocol. This simplifies the wiring and allows for seamless integration into the ControlLogix system.
