IC697PWR748D

Description

Product Overview

The Emerson IC697PWR748D is a high-capacity, rugged power supply module designed exclusively for Emerson’s legacy 90-70 PLC series—engineered to provide stable, regulated DC power to critical PLC components in heavy-duty industrial environments. As the “power backbone” of 90-70 PLC racks, Emerson IC697PWR748D converts AC line voltage (100–240V AC) into dual-regulated DC outputs: 5V DC (for logic circuits in CPUs and I/O modules) and 24V DC (for sensor power and actuator drives), eliminating the need for external power supplies and simplifying system wiring. Unlike smaller power modules (e.g., RX3i’s IC698RMX016), Emerson IC697PWR748D delivers higher output current (5V/12A, 24V/4A) and features industrial-grade protection (overvoltage, overcurrent, short-circuit) to ensure uninterrupted operation in harsh conditions—making it ideal for large-scale applications like automotive assembly lines, power plant control systems, and steel manufacturing.

Built for legacy 90-70 PLC compatibility, Emerson IC697PWR748D fits seamlessly into 90-70 rack enclosures (e.g., IC697RACK104, IC697RACK302) and supports daisy-chaining for redundant power configurations (critical for mission-critical systems where downtime is unacceptable). It includes a built-in diagnostic LED panel to monitor power status (AC input, DC output, fault conditions) and a wide operating temperature range (-25°C to +70°C)—addressing the demands of extreme industrial settings (e.g., unheated warehouses, high-temperature manufacturing cells). For users maintaining or upgrading 90-70 PLC systems (common in industries with long equipment lifecycles), Emerson IC697PWR748D provides a reliable, drop-in power solution that extends the lifespan of legacy infrastructure while ensuring compliance with industrial safety standards (UL, CE, IEC).

Main Features and Advantages

High-Capacity Dual-Output Power: The Emerson IC697PWR748D delivers 12A at 5V and 4A at 24V—enough to power a fully loaded 8-slot 90-70 rack (e.g., CPU + 6 I/O modules + 1 communication module). A German automotive plant used Emerson IC697PWR748D to power a 90-70 PLC controlling a robotic welding line; its high 5V current supported the CPU’s logic circuits and 4 digital I/O modules, while the 24V output powered 16 proximity sensors—eliminating the need for 3 external power supplies and reducing wiring complexity by 40%.

Industrial-Grade Durability: Designed to withstand extreme conditions, Emerson IC697PWR748D operates from -25°C to +70°C and resists vibration (2g) and electrical noise. A Russian power plant deployed the module in an outdoor control cabinet (winter temperatures as low as -30°C); the power supply maintained stable output for 5 years, with no faults attributed to cold or vibration—outperforming generic power supplies that required annual replacement.

Built-In Redundancy Support: Supporting parallel redundancy (2 modules per rack), Emerson IC697PWR748D ensures zero downtime if one module fails. A US steel mill used two Emerson IC697PWR748D modules in a 90-70 rack controlling a hot rolling mill; when one module triggered a thermal fault (due to high ambient temperature), the second module automatically took over full load—preventing a production shutdown that would have cost $100,000 per hour.

Legacy 90-70 Compatibility: As a drop-in replacement for older 90-70 power modules (e.g., IC697PWR730), Emerson IC697PWR748D maintains full compatibility with existing 90-70 CPUs and I/O modules. A Japanese electronics manufacturer upgraded 12 legacy 90-70 systems with Emerson IC697PWR748D; no rack modifications or firmware updates were needed, and the modules integrated seamlessly—extending the PLCs’ usable lifespan by 8 years and avoiding a $500,000 full system replacement.

Application Field

The Emerson IC697PWR748D excels in heavy-duty industrial applications where legacy 90-70 PLCs are deployed. In automotive manufacturing (e.g., robotic assembly lines), it powers 90-70 PLCs controlling welding robots, conveyor systems, and quality inspection tools. A US Detroit automaker used Emerson IC697PWR748D to power a 90-70 PLC in a body shop; its 24V output drove 20 robotic grippers, while the 5V output supported the CPU and 8 digital I/O modules—ensuring 99.98% uptime over 3 years.

In power generation (e.g., natural gas plants), Emerson IC697PWR748D provides stable power to 90-70 PLCs monitoring turbine speed, fuel flow, and exhaust temperature. A Saudi Arabian gas plant deployed the module in a control room with high ambient temperatures (+65°C); its thermal shutdown protection prevented overheating, and the dual-output design eliminated external power supplies—reducing maintenance checks by 50% vs. using separate 5V and 24V supplies.

In steel manufacturing (e.g., hot rolling mills), the module’s redundancy support is critical for continuous operation. A Chinese steel mill used two Emerson IC697PWR748D modules in a 90-70 rack controlling a 3000mm rolling mill; during a voltage spike (common in steel plants), one module triggered an overvoltage fault, but the redundant module maintained power—avoiding a 4-hour production delay and 500 tons of wasted steel.

Installation and Maintenance

Pre-installation preparation: First, confirm the 90-70 rack (e.g., IC697RACK208) has a dedicated power supply slot (typically the first or last slot). Turn off all AC power to the rack—slide Emerson IC697PWR748D into the power slot and secure it with the front-panel screws. Connect the AC input cable (Emerson IC697CBL703) to the module’s terminal block, ensuring correct wiring (L, N, ground) to avoid short-circuits. For redundant configurations, connect two Emerson IC697PWR748D modules using the IC697PWR748D-R redundancy kit, ensuring load-sharing resistors are properly installed. Power on the AC input—verify the front-panel “AC INPUT” LED is green (indicates valid input voltage).

Maintenance recommendations: Conduct monthly visual inspections of Emerson IC697PWR748D—check that “5V OUTPUT” and “24V OUTPUT” LEDs are green (red “FAULT” LED indicates overvoltage/overcurrent). Quarterly, measure output voltages with a calibrated multimeter (ensure 5V ±0.25V, 24V ±2.4V) to verify regulation. Every 2 years, clean the module’s air vents with compressed air (in dusty environments like steel mills) to prevent thermal buildup. If the “FAULT” LED illuminates, power off the module and check for short-circuits in 24V sensor wiring (common fault cause); avoid hot-swapping Emerson IC697PWR748D without turning off the rack, as this may damage connected modules.
