170AAO92100 | Schneider Electric | Modicon Momentum 4-Channel Analogue Output Base

Product Overview

The Schneider Electric 170AAO92100 serves as a high-precision analogue output base for the Modicon Momentum automation platform. This module provides four independent channels capable of delivering both voltage (+/- 10 V) and current (4...20 mA) signals to field actuators, valves, and drive controllers. By utilizing a full 16-bit signed data format, it ensures granular control and smooth signal ramps for demanding process applications. We supply this component as 100% brand new original hardware, ensuring factory-spec accuracy and long-term stability for your distributed I/O architecture.

Engineering Advantages

• High-Resolution Signal Control: The 16-bit signed data format provides superior resolution compared to standard 8-bit or 12-bit modules. This precision allows for the fine-tuning of variable speed drives and proportional valves, directly improving process yield and reducing mechanical wear.

• Rapid Loop Response: A 2 ms update time ensures that the field devices receive control commands with minimal latency. This speed supports fast-acting PID loops and dynamic positioning tasks that require immediate output adjustments.

• Rugged Electrical Isolation: The module features 500 V AC isolation between channels and ground, along with a 250 V permissible common mode voltage. These specifications protect the PLC backplane from ground loops and electrical surges common in heavy industrial wiring.

• Flexible Fail-Safe Modes: Upon a communication fault or processor halt, the 170AAO92100 defaults to a "Hold" state. This preserves the last valid output value, preventing sudden process shutdowns or equipment damage caused by erratic signal drops.

• Compact Momentum Footprint: The standard module format integrates seamlessly with any Momentum I/O base or processor adapter. This modularity solves the problem of limited cabinet space by allowing for high-density analogue control in a small physical envelope.

FAQs

• Can I mix voltage and current outputs on the same 170AAO92100 base?

  Yes. The base supports both +/- 10 V and 4...20 mA ranges. You configure the specific output type per channel within your PLC programming software (such as Concept or Unity Pro).

• Does the module require external power?

  Yes. The 170AAO92100 requires an external 24 V DC power supply to drive the analogue output circuits. The module monitors this supply and provides status feedback via local LEDs.

• How do the local LEDs assist in troubleshooting?

  The base includes four dedicated channel status LEDs. These indicators allow technicians to verify at a glance whether each individual output is active or if a channel-specific fault has occurred, reducing the time required for field diagnostics.

• What is the condition of this unit?

  We guarantee this 170AAO92100 is 100% Brand New original stock. It arrives in factory-sealed packaging with a unique GTIN (3595861147720), ensuring it meets all Schneider Electric quality standards for immediate deployment.
