GE 169C4752G0001
Product Name: GE Fanuc RX3i 8-Channel Analog Input Module
Product Introduction: The 169C4752G0001 is an 8-channel analog input module designed for the GE Fanuc RX3i PLC system. It acquires continuously varying analog signals from the field—such as temperature, pressure, flow, and level (4-20mA or 0-10V)—performs A/D conversion, and transmits the digitized data to the PLC for processing.

Structural Features: Standard 169C module form factor compatible with RX3i PLC racks. Front panel: 8 channel LEDs plus signal-type indicator. Backplane: standard RX3i bus connector plus analog signal terminal block.
Application Scenarios: Chemical process control, power instrumentation acquisition, water treatment, HVAC, pharmaceutical manufacturing.
Installation Requirements: Insert into a standard RX3i rack slot and lock into position. 4-20mA signal wiring must use shielded twisted pair with the shield grounded at a single point. In voltage input mode, the signal source impedance must be less than 100Ω.
Usage Precautions: Never disconnect the signal loop in current input mode, as this may damage the module. Unused channels must be shorted or connected to an appropriate load resistor.
