IC698CMX016-ED

Description

Product Overview

The Emerson IC698CMX016-ED is a high-precision multi-channel analog I/O combination module in Emerson’s RX3i PLC series, engineered for industrial control systems requiring integrated analog signal acquisition and output. As a “dual-function analog bridge” for RX3i PLCs, Emerson IC698CMX016-ED combines 8 differential analog input channels (for sensor data collection) and 8 analog output channels (for actuator control) in a single rack-mount module—eliminating the need for separate input and output modules and saving up to 50% of rack space. The “-ED” suffix denotes enhanced precision (16-bit resolution) and industrial durability, including anti-aliasing filters for input signals and short-circuit protection for outputs, making it ideal for process control scenarios with strict accuracy requirements (e.g., chemical reactor temperature regulation, water treatment pH control).

Unlike single-function RX3i analog modules (e.g., Emerson IC698AI016 for input only, IC698AO016 for output only), Emerson IC698CMX016-ED streamlines system design by integrating both functions, while maintaining 16-bit resolution (±0.05% full-scale accuracy) for reliable signal conversion. It supports a wide range of analog signal types: input channels accept 4–20mA DC, 0–10V DC, and thermocouple (Type J/K/T) signals, while output channels provide 4–20mA DC or 0–10V DC signals—compatible with most industrial sensors (e.g., pressure transmitters, temperature probes) and actuators (e.g., control valves, variable-speed drives). For users deploying RX3i PLCs in process industries (e.g., chemical, petrochemical, municipal water treatment), Emerson IC698CMX016-ED offers a space-efficient, high-precision analog solution that reduces module count, simplifies wiring, and ensures consistent signal integrity for critical process control loops.

Main Features and Advantages

Space-Saving Integrated Design: By combining 8 input and 8 output channels in one module, Emerson IC698CMX016-ED reduces the number of modules needed for analog control—saving two rack slots compared to using separate Emerson IC698AI016 (input) and IC698AO016 (output) modules. A German chemical plant used Emerson IC698CMX016-ED in a 10-slot RX3i rack for a reactor control system; the integrated design freed up slots for additional digital I/O modules, eliminating the need to upgrade to a larger 20-slot rack and saving $2,000 in hardware costs.

High Precision for Critical Processes: With 16-bit resolution and ±0.05% full-scale accuracy, Emerson IC698CMX016-ED ensures reliable conversion of small analog signals—critical for processes like pharmaceutical batch mixing, where 0.1% deviations in temperature or pressure can affect product quality. A Swiss pharmaceutical manufacturer used the module to monitor and control 6 mixing tanks; its precise input sampling (100 samples/sec) detected minor temperature fluctuations (±0.2°C), and accurate output signals adjusted heating elements in real time, reducing batch rejection rates by 12%.

Versatile Signal Compatibility: Supporting multiple input/output signal types (4–20mA, 0–10V, thermocouples), Emerson IC698CMX016-ED eliminates the need for signal converters. A US municipal water treatment plant used it to connect 8 pH sensors (4–20mA input) and 8 control valves (4–20mA output); the module’s thermocouple input capability also enabled monitoring of heater temperatures (Type K thermocouple) in the same system, reducing component count by 30% vs. using specialized modules.

Robust Protection for Industrial Reliability: Equipped with anti-aliasing filters (to reduce noise) and short-circuit protection (for outputs), Emerson IC698CMX016-ED withstands harsh industrial conditions. A South African mining plant deployed the module in a dusty, high-vibration environment to control pump pressure; the anti-aliasing filter minimized electrical noise from nearby motors, and short-circuit protection prevented module damage when a valve actuator failed, ensuring 99.9% uptime over 18 months.

Application Field

The Emerson IC698CMX016-ED excels in process control and industrial automation across three key sectors. In chemical and petrochemical processing (e.g., reactor temperature/pressure control), it monitors sensor data and adjusts control valves in real time. A Singaporean petrochemical plant used Emerson IC698CMX016-ED to control a distillation column—8 input channels tracked temperature at different column stages (Type K thermocouples), and 8 output channels adjusted steam valves (4–20mA), ensuring consistent product purity and reducing energy consumption by 8%.

In municipal water treatment (e.g., filtration and disinfection), Emerson IC698CMX016-ED integrates sensor data and actuator control. A Canadian water plant used the module to monitor turbidity (0–10V input) and pH (4–20mA input) of raw water, while output channels adjusted coagulant dosing pumps (4–20mA) and chlorine injectors (0–10V), improving water quality compliance and reducing chemical waste by 15%.

In pharmaceutical manufacturing (e.g., batch mixing and sterilization), the module’s high precision ensures compliance with strict quality standards. An Indian pharmaceutical firm used Emerson IC698CMX016-ED to control 4 autoclaves—input channels measured temperature (Type J thermocouples) and pressure (4–20mA transmitters), and output channels regulated steam flow, meeting WHO GMP requirements and reducing batch documentation time by 20% (via accurate data logging).

Installation and Maintenance

Pre-installation preparation: First, confirm the RX3i rack (e.g., IC698Rack10) has an available slot and that the CPU (e.g., Emerson IC698CPE030) firmware is ≥V3.5. Turn off rack power—install Emerson IC698CMX016-ED in the desired slot and ensure it is fully seated in the backplane. Connect the external 24V DC power supply to the module’s terminal block (follow polarity markings to avoid damage). Wire sensors to input channels (e.g., 4–20mA transmitters to terminals 1–2) and actuators to output channels (e.g., control valves to terminals 17–18), using shielded cables (Emerson IC698CBL040) for noise reduction. Power on the rack—verify the module’s “POWER” LED is steady green.

Maintenance recommendations: Conduct monthly checks of Emerson IC698CMX016-ED’s LEDs—ensure “POWER” is green and “FAULT” is off (illumination indicates short-circuit or calibration error). Quarterly, verify input/output accuracy using a calibrated signal generator (e.g., 4mA/20mA for current channels) and adjust via the RX3i Configuration Tool if needed. Perform annual factory-calibrated field calibration to maintain ±0.05% accuracy. In dusty or humid environments, clean the module’s terminal block with a dry brush every 3 months to prevent corrosion. If a channel fails, use the tool’s diagnostic function to isolate the issue (e.g., open circuit, short circuit); avoid hot-swapping Emerson IC698CMX016-ED without stopping the PLC, as this may cause signal spikes.
