IC697PWR722 GE Fanuc Series 90-70 Power Supply
Product Introduction
The GE Fanuc IC697PWR722 is a robust power supply module built for the Series 90-70 programmable controller family. It delivers a total output power of 90 Watts, drawing from a 24 VDC nominal input. This module provides three regulated voltage outputs: 5 VDC, 12 VDC, and -12 VDC. Engineers select the IC697PWR722 when they need reliable, clean DC power for their Series 90-70 racks. Additionally, this unit supports dual-rack operation, making it a flexible choice for expanded systems.
Technical Specifications of the IC697PWR722
The GE Fanuc IC697PWR722 operates with a nominal input voltage of 24 VDC, accepting a range from 21 to 32 VDC. Its maximum output power reaches 90 Watts. The three regulated output voltages deliver currents of 16.5 A at 5 VDC, 1.5 A at 12 VDC, and 1 A at -12 VDC. The inrush energy rating is 22 J at 32 VDC. Overvoltage protection limits the 5V output between 6 and 7 Volts. This power supply also includes overcurrent protection on all outputs and inputs, safeguarding connected modules from damage.
Dual-Rack Support and Expansion
A notable feature of the IC697PWR722 is its dual-rack capability. When a second rack connects to this power supply, only the 5 VDC output is required for that expansion rack. The current drawn by the second rack must remain below 5.2 Amps. Additionally, the second rack must be positioned close to the primary rack, with the connecting cable length not exceeding 3 feet. Therefore, this feature enables system expansion without requiring an additional power supply module for the secondary rack.
Physical Installation and Mounting
The GE Fanuc IC697PWR722 mounts on the left side of a Series 90-70 rack. It offers two installation methods. First, it can be mounted with the right side plate attached at the factory, directly onto a panel. Second, it can be attached to the left side of the rack using a panel, which requires removing the right side plate and using additional hardware. This flexibility accommodates different cabinet layouts and space constraints. For proper operation, the IC697PWR722 must connect to a compatible adapter module like the IC697PWR720, which routes the power supply outputs to the rack backplane.
System Integration and Monitoring
The IC697PWR722 does more than just deliver power. It also monitors the TTL signal of the power supply module and defines the logic of operations with this module. This integration ensures that the power supply communicates effectively with the Series 90-70 CPU and I/O modules. System reset signals are also managed through this module, contributing to orderly start-up and shutdown sequences.
Environmental and Mechanical Ratings
The GE Fanuc IC697PWR722 operates within a temperature range of 0 to 60°C. It withstands shocks of 15 G for 11 milliseconds, making it suitable for industrial environments with moderate vibration. Its standard format fits the Series 90-70 rack system seamlessly.
Installation Guidelines
Installing the IC697PWR722 requires careful attention to power and grounding. First, ensure the rack is powered off and the input supply is disconnected. Then, mount the power supply on the left side of the rack using the chosen installation method. Connect the adapter module (IC697PWR720) to route outputs to the backplane. For dual-rack configurations, attach the second rack with the 5V cable, ensuring the current draw is within limits. Finally, connect the 24 VDC input, apply power, and verify the output voltages.
