170AAI52040 Schneider Modicon Momentum PLC Analog Input Module

Product Description

The 170AAI52040 is a precision analog input module for the Modicon Momentum distributed I/O platform. It provides four high-resolution analog input channels for integrating field instruments such as pressure transmitters, flow meters, and temperature transmitters into PLC-based control systems. The snap-on modular design allows direct mounting to a Momentum processor or communication adapter, delivering a compact and flexible solution for field-level data acquisition.

Technical Specifications

Application

Well suited for distributed analog measurement in space-constrained or decentralized systems, including:

• Process instrumentation monitoring

• Skid-mounted systems

• Water and wastewater treatment

• HVAC and energy management

FAQ

Does the 170AAI52040 support thermocouples or RTDs directly?
No. This module is intended for standard voltage and current signals. Dedicated Momentum temperature input modules should be used for direct TC or RTD connections.

Can the module be hot-swapped?
Hot-swap capability depends on the processor or communication adapter. As best practice, power should be removed before detaching the module to avoid data corruption.

Is the 24 VDC supply used for loop power?
Yes. The 24 VDC supply powers the module and can typically be used to support sensor loop power, depending on wiring configuration.
