General Information

Core Description

The IC697PWR710 is a high-performance 55-watt rack-mounted power supply module engineered for industrial environments. Fully compatible with the Series 90-70 backplane, this unit features active power factor correction on AC inputs and works seamlessly with multi-rack setups to deliver a stable 11-amp output at 5 VDC while providing comprehensive overvoltage and short-circuit protection.

Specific Application

• Delivering regulated 5 VDC logic power up to 11 amperes for multi-slot microprocessors and smart communication modules in heavy-duty Series 90-70 PLC racks.
• Powering dual-rack hardware topologies through a specialized 3-foot power extension cable when the combined electrical load falls within the 55W threshold.
• Operating in severe power infrastructure installations requiring active unity power factor correction to eliminate oversized circuit breakers and field wiring.

Ordering Information

System Compatibility

Rack Architecture: Plugs directly into a 48-pin backplane connector in the leftmost slot of any standard IC697 or VME Integrator rack.

Input Infrastructure: Operates universally from a wide input range of 90 to 264 VAC (47 to 63 Hz) or 100 to 150 VDC.

Dual-Rack Integration: Supports expansion to a secondary rack using the IC697CBL700 or IC697CBL713 prewired extension cables.

Alternative Models & Functional Differences

IC697PWR712 (Co-Listed Alternative): Shares identical 55-watt capacities, 11-amp 5 VDC output, and multi-voltage AC/DC inputs with the IC697PWR710 model.

IC693 Power Supplies: Built exclusively for the smaller Series 90-30 PLC platform, utilizing completely different mechanical dimensions and a standard 6-terminal strip rather than the 48-pin VME style backplane link.

Legacy Non-Power Factor Corrected Modules: Lack internal active unity power factor networks, thereby demanding larger circuit protection breakers and thicker field wire sizing during plant installation.

Installation & Troubleshooting FAQ

Q1: What unique wire and terminal specifications are required for incoming electrical connections?

A: Field power connections must be completed using copper AWG #16 wire rated for 75 degrees Celsius, while rack-to-earth grounding loops require thicker AWG #12 wire torqued exactly to 12 in-lb to ensure maximum electrical noise immunity.

Q2: How does the module react to short-circuits or electrical overcurrent events on the logic bus?

A: The module features an integrated electronic overcurrent limit typically set at 12 amperes. If a load threshold or short-circuit occurs, the output voltage drops automatically and safely remains clamped without opening the internal fuse until the fault is completely removed.

Q3: What is the rated ride-through timing buffer during a total loss of input power?

A: The supply incorporates energy-storage capacitors that guarantee a minimum ride-through time of 21 milliseconds from the initial loss of AC power, allowing the PLC processing logic to complete an orderly shutdown cycle before the system reset triggers.

Q4: What explicit parameter limits are enforced by the electronic overvoltage clamping circuit?

A: The unit actively monitors the 5 volt output rail. If an overvoltage condition arises and the internal bus exceeds 6.2 volts, the electronic protection circuit will immediately clamp the output loop to shield downstream backplane electronics.

Q5: Can a single supply safely distribute 5 VDC power to two adjacent equipment racks?

A: Yes, provided the secondary rack only demands 5 volt power, its individual current draw stays below 5.2 amperes, and the combined cumulative load of both racks does not cross the maximum 55W system ceiling.
