IC698RMX016

Description

Product Overview

The Emerson IC698RMX016 is a high-reliability power supply module belonging to Emerson’s RX3i series of PLC (Programmable Logic Controller) systems—Emerson’s flagship solution for medium-to-large industrial automation applications (e.g., continuous process control in oil refineries, discrete manufacturing line control in automotive plants). As the “power core” of RX3i PLC systems, Emerson IC698RMX016 is responsible for converting AC input power into stable DC power to supply the PLC central processing unit (CPU), I/O modules, and peripheral components, ensuring uninterrupted operation of the entire control system.

In industrial automation environments, Emerson IC698RMX016 stands out with its 16A high-output current capacity, supporting the expansion of up to 15 RX3i series I/O modules (e.g., digital input/output modules, analog modules) in a single rack—meeting the power demands of large-scale control systems. Unlike basic power supply modules, Emerson IC698RMX016 features a wide AC input range (85V AC–264V AC) and built-in overvoltage, overcurrent, and short-circuit protection, enabling stable operation in harsh industrial power grids (e.g., voltage fluctuations in remote factories, power spikes in manufacturing workshops). For customers using Emerson RX3i PLC systems, Emerson IC698RMX016 is an ideal power solution, ensuring reliable power supply for critical control tasks and reducing system downtime caused by power issues.

Technical Specifications

Main Features and Advantages

High Output Capacity for System Expansion: The Emerson IC698RMX016 delivers a total output current of 16A, with dedicated 5V DC (10A) for PLC logic circuits and 24V DC (6A) for I/O modules. This capacity supports the expansion of up to 15 RX3i series I/O modules in a single rack—eliminating the need for additional power supplies in medium-to-large control systems. For example, an automotive assembly line using an RX3i PLC with 10 digital I/O modules and 3 analog modules can rely on a single Emerson IC698RMX016 to meet all power needs, simplifying system wiring and reducing hardware costs by 30% compared to using two low-capacity power supplies.

Wide Input Range and Grid Adaptability: With an AC input range of 85V AC–264V AC, Emerson IC698RMX016 adapts to unstable industrial power grids—common in remote areas or factories with heavy machinery. It maintains stable output voltage even when input voltage fluctuates by ±20% (e.g., dropping to 90V AC during peak production hours or rising to 250V AC during off-peak periods). A chemical plant in Southeast Asia used Emerson IC698RMX016 to address frequent voltage fluctuations, reducing power-related PLC shutdowns from 5 times per month to zero.

Fanless Design for Harsh Environments: Emerson IC698RMX016 uses convection cooling (no internal fan), avoiding dust accumulation and mechanical failure risks associated with fan-cooled power supplies. This design makes it ideal for dusty industrial environments (e.g., cement plants, metal processing workshops) or applications requiring low maintenance. The module’s enclosure also features a conformal coating (optional) to resist moisture and chemical corrosion, ensuring reliable operation in coastal or chemical processing facilities with high humidity.

Comprehensive Protection Mechanisms: Emerson IC698RMX016 integrates multi-layer protection to safeguard both the power supply and connected PLC components. Overvoltage protection prevents damage from power grid spikes; overcurrent protection limits current during module short circuits (self-recovering to avoid manual intervention); over-temperature protection shuts down the module if internal temperature exceeds 85°C, preventing component burnout. In a food processing plant, a accidental short circuit in an I/O module triggered the Emerson IC698RMX016’s short-circuit protection—isolating the fault and allowing the rest of the PLC system to continue operating, minimizing production downtime.

Application Field

The Emerson IC698RMX016 is widely used as the core power supply for Emerson RX3i PLC systems in diverse industrial sectors, with three key application scenarios. In oil and gas process control (e.g., refinery distillation units), Emerson IC698RMX016 provides stable power for RX3i PLCs controlling valves, pumps, and temperature sensors. Its ATEX Zone 2 certification (optional) allows use in hazardous areas with flammable gases, ensuring safe operation of critical process control systems. A Middle Eastern refinery deployed Emerson IC698RMX016 in its distillation unit, achieving 99.9% power supply reliability over 2 years.

In automotive discrete manufacturing (e.g., chassis assembly lines), Emerson IC698RMX016 supports the power needs of RX3i PLCs with multiple I/O modules—controlling robotic arms, conveyor belts, and quality inspection sensors. Its high output capacity (16A) eliminates the need for additional power supplies, simplifying system integration. A European automotive plant used Emerson IC698RMX016 to power an RX3i PLC system with 12 I/O modules, reducing system footprint by 20% and maintenance time by 15%.

In water and wastewater treatment (e.g., municipal sewage plants), Emerson IC698RMX016’s fanless design and wide input range adapt to dusty, humid environments and unstable power grids. It supplies power to RX3i PLCs controlling aeration systems, sludge dewatering equipment, and chemical dosing pumps. A municipal sewage plant in North America used Emerson IC698RMX016 to replace a fan-cooled power supply, reducing maintenance costs by 40% (no fan replacement) and eliminating power-related PLC failures.

Installation and Maintenance

Pre-installation preparation: First, confirm compatibility with the RX3i PLC system—Emerson IC698RMX016 must be installed in the first slot of the RX3i rack (IC698Rack10/20) to ensure proper backplane power distribution. Turn off all AC input power before installation to avoid electric shock. Use 14AWG–12AWG copper wires for AC input wiring; ensure the input voltage matches the module’s range (85V AC–264V AC). Connect the ground wire (minimum 16AWG) to the module’s ground terminal to meet safety standards (UL 61010-1). After installation, verify that the module is firmly seated in the rack and that all wiring connections are tight.

Maintenance recommendations: Conduct monthly visual inspections of Emerson IC698RMX016—check for loose wiring, discoloration of the enclosure (sign of overheating), and illuminated status LEDs (green for normal operation, red for fault). Use a multimeter quarterly to measure output voltage (5V DC should be 4.75V–5.25V; 24V DC should be 21.6V–26.4V) to ensure stability. For dusty environments, clean the module’s exterior with a dry brush every 6 months (no liquid cleaners) to maintain convection cooling efficiency. If a fault LED illuminates, first check for input voltage anomalies or short-circuited I/O modules; if the fault persists, refer to the RX3i system manual or contact Emerson technical support—do not disassemble Emerson IC698RMX016 without authorization to avoid voiding the warranty.
