The 1762-IF4 from Rockwell Automation is a 4-channel analog input module designed for the MicroLogix 1200 / 1100 / 1400 PLC families.
It is used to acquire and condition analog signals from industrial sensors such as:
- Pressure transmitters
- Temperature transmitters
- Flow sensors
- Analog voltage/current devices
This module is part of the 1762 MicroLogix expansion I/O series.
