Product Overview

The IC697PWR711 is a high-capacity, 100-watt triple-output power supply module engineered specifically for the General Electric Series 90-70 Programmable Logic Controller (PLC) family. This module serves as the primary energy source for the system backplane, converting AC or DC input voltages into the regulated DC power required by CPU, I/O, and communication modules. Designed for high reliability in mission-critical Distributed Control Systems (DCS), the IC697PWR711 features advanced power factor correction and integrated electronic overvoltage protection. Its modular, slide-in architecture allows for seamless integration into any standard IC697 rack, typically occupying the dedicated leftmost slot to facilitate logic-level sequencing and power distribution across the 48-pin backplane interface.

Technical Performance and Electrical Specifications

The IC697PWR711 is built to provide stable, filtered power under varying industrial load conditions:

• Versatile Input Compatibility: Supports wide-range inputs including 120/240 VAC (90–264 VAC range) and 125 VDC (100–150 VDC range).

• Triple DC Output Rails: Provides +5 VDC at 20 Amps, +12 VDC at 2 Amps, and -12 VDC at 1 Amp to support diverse module requirements.

• Power Factor Correction (PFC): Integrated circuitry optimizes AC energy usage and reduces harmonic distortion on the plant power grid.

• Fault Protection: Comprehensive electronic safeguarding against short circuits, overcurrent, and overvoltage events to prevent damage to downstream PLC components.

• Holdup Capability: Features a "ride-through" function that maintains output voltage for at least one full input line cycle during momentary power loss at full load.

• Dual Rack Support: Capable of powering two separate racks simultaneously via a prewired interconnection cable, provided the combined load does not exceed the 100-watt threshold.

Design and Installation Characteristics

• Rack Integration: Designed for high-density mounting in IC697 or VME Integrator’s racks with a plug-and-play 48-pin connector.

• Thermal Management: Efficient heat dissipation design, though power derating is recommended when operating at the lower end of the voltage range or in high-temperature ambient environments.

• Diagnostic Indicators: Front-panel LEDs provide immediate status feedback regarding input power presence and output health.

• Mechanical Build: Compact dimensions of 20 x 11.5 x 5.7 cm and a robust 0.9 kg weight suitable for high-vibration industrial settings.

Industrial Applications

As a core component of the Series 90-70 automation platform, the IC697PWR711 is utilized in:

• Complex Process Control: Providing reliable logic power for chemical processing and refinery DCS.

• Power Generation: Supporting GE Mark VIe systems and turbine control architectures where continuous uptime is mandatory.

• Infrastructure Management: Powering large-scale water treatment and utility automation systems.

• Manufacturing Automation: Serving as the electrical foundation for high-speed assembly and material handling PLC racks.
