Product Details

Product Overview

The Emerson 396604-03-0 functions as a high-performance Isolated Analog Input (AI) module specifically engineered for the ControlWave™ Micro RTU/PLC ecosystem. This module bridges the gap between field transmitters and your control logic by converting signals from pressure, temperature, and flow sensors into precise digital data. Featuring High Common-Mode (HCM) isolation, it excels in electrically noisy environments where ground loops often degrade signal integrity. This unit arrives in 100% Brand New condition, ensuring maximum MTBF (Mean Time Between Failures) for your critical infrastructure.

Technical Specifications

This module provides a robust interface for diverse field instrumentation through the following parameters:

Feature	Specification
Channels	8 Isolated Differential Inputs
Signal Ranges	Configurable: 4–20 mA, 1–5 VDC, 0–10 VDC
Resolution	16-bit High Precision
Isolation	Optical Isolation with HCM Rejection
Power Consumption	309 mA @ 24 VDC
Operating Temp	-40 °C to +70 °C
Certifications	UL, CE, Class I Div. 2 (Hazardous Locations)
Dimensions	100 × 50 × 150 mm

Engineering Advantages

Eliminate Ground Loops: The optical isolation barrier prevents circulating currents between the field ground and the PLC backplane, protecting your processor from surges and ensuring rock-solid data accuracy.
Superior Noise Immunity: The HCM design filters out electromagnetic interference (EMI) typically found near large motors or high-voltage switchgear, making it ideal for power generation and refinery applications.
Flexible Field Deployment: You can configure each channel for different signal types (current or voltage). This versatility reduces the need for multiple spare part types in your inventory.
Rugged Reliability: With a wide operating temperature range (-40 °C to +70 °C), this module thrives in remote oil and gas pipeline stations where climate control is unavailable.

FAQs

Q: Can I use the 396604-03-0 to replace older Bristol Babcock modules?

A: Yes. As Emerson integrated the Bristol Babcock ControlWave line, this module maintains full backward compatibility with existing ControlWave Micro backplanes. Ensure your firmware supports the HCM isolated configuration before hot-swapping.

Q: Does this module support loop-powered 4-20 mA transmitters?

A: Absolutely. The 396604-03-0 supports both external and loop-powered configurations. You can wire it to utilize the internal 24 VDC supply or integrate it into an existing external power loop.

Q: How does "HCM" isolation differ from standard isolation?

A: HCM (High Common Mode) isolation specifically targets high-frequency noise and significant voltage potential differences between the input signal and the system ground. It provides a much cleaner signal in "dirty" electrical environments compared to standard non-isolated or basic isolated cards.
