GE IC697RCM711C PLC Power Supply Modules

The GE IC697RCM711C, also cataloged as the IC697RCM711 Power Supply Module, operates as a dedicated hardware component for high-density power conversion and backplane rail regulation within Series 90-70 PLC platforms. Mounted directly into the leftmost slot of standard Series 90-70 racks, the unit converts 120/240 VAC or 125 VDC input sources into regulated DC voltage rails (+5 VDC, +12 VDC, -12 VDC) delivering up to 100 W total output. The module supplies current to CPU processors, I/O modules, and field communication devices across one or two interconnected rack configurations.

Hardware Specifications

Backplane Bus Communication Velocity & Network Integration

The IC697RCM711C maintains precise backplane voltage stability across variable module loading conditions, directly preventing logic errors and backplane bus communication velocity degradation caused by voltage ripple. Its internal regulated output stages supply high-density logic cards with up to 20 A on the +5 VDC line, while integrated overvoltage and short-circuit protection circuits shield backplane communication channels from external power transients. Firmware flash compatibility and CPU execution stability are preserved across system power cycles via fast-acting internal shutoff routines during line-voltage dropout events.

Frequently Asked Questions

Q: What are the primary output current limits for each voltage rail delivered to the backplane?

A: The module delivers a total power budget of 100 W divided into three regulated DC rails: +5 VDC rated at 20 A, +12 VDC rated at 2 A, and -12 VDC rated at 1 A.

Q: Can the power supply module accept high-voltage DC input in place of standard AC mains?

A: Yes, the dual-input power circuit operates from either 120/240 VAC at 50/60 Hz or a direct 125 VDC source without requiring manual jumper reconfiguration.

Field Installation Guidelines

1. Ensure main AC/DC supply power is de-energized prior to inserting or removing the module from the rack.
2. Align the module card edges with the leftmost dedicated slot guides of the Series 90-70 rack chassis.
3. Slide the unit firmly backward until the rear backplane connectors fully seat into the rack backplane receptacle.
4. Tighten the top and bottom retaining screws to secure the physical ground path and prevent connector movement under vibration.
5. Wire incoming AC (120/240 VAC) or DC (125 VDC) power leads to the removable terminal block, verifying solid single-point ground connection before applying power.
