Emerson IC695PSD040F DC Power Supply Module

Emerson IC695PSD040F PACSystems RX3i DC Power Supply Module Overview

The Emerson IC695PSD040F is a 40-Watt DC power supply module designed for use with the Emerson (formerly GE Fanuc/GE Intelligent Platforms) PACSystems RX3i Universal Backplane. It provides the necessary power to the RX3i modules installed on the backplane, ensuring stable and reliable operation of the Programmable Automation Controller (PAC) system. The "F" suffix often denotes a specific revision or manufacturing iteration, but the core functionality remains consistent.

Product Detailed Description

• Core Function: The primary function of the IC695PSD040F is to convert an external 24 VDC input power source into regulated power for the RX3i backplane and its installed modules. This includes providing 5.1 VDC and 3.3 VDC for the modules, and sometimes a 24 VDC output for external use or relay modules.

• Mounting: It's designed to snap into any slot on an RX3i universal backplane (IC695 series), typically occupying slot 0.

• Power Output: It delivers a maximum of 40 Watts of total output power across its various voltage outputs. The output power is distributed between the 5.1 VDC and 3.3 VDC rails, with individual maximums for each (e.g., 30 Watts max for 5.1 VDC and 30 Watts max for 3.3 VDC).

• Indicator LEDs: The module typically features four LED indicators to provide visual status feedback:

• Power: Indicates if the power supply is on.

• P/S Fault: Indicates a general power supply fault.

• Overtemperature: Warns of an internal overtemperature condition.

• Overload: Indicates an overload condition on one of the outputs.

• Protection: Includes internal overcurrent protection for its outputs. If an overload or short circuit occurs, the power supply will shut down.

• Ride-Through Time: Provides a specified ride-through time (e.g., 10 ms) during temporary power interruptions, ensuring continuous operation of the system for short dips.

• On/Off Switch: Some versions may include a physical on/off switch for convenient power control.

• Field Wiring: Utilizes screw terminals for connecting the DC input power and ground.

Product Advantages

• Reliable Power: Provides stable and regulated DC power to the RX3i system, crucial for reliable PLC operation.

• Compact Integration: Designed to seamlessly integrate into the RX3i universal backplane, saving space in control cabinets.

• Diagnostic LEDs: Clear LED indicators enable quick visual troubleshooting of power supply status, faults, overtemperature, and overloads.

• Robust Design: Built for industrial environments, ensuring durability and longevity.

• Compatibility: Fully compatible with the Emerson (GE Fanuc) PACSystems RX3i platform, allowing for easy replacement or new system builds.

• Overload Protection: Internal electronic limiting and shutdown protect the power supply and connected modules from damage due to overcurrents or short circuits.

• Ride-Through Capability: Helps maintain system operation during brief power disturbances.

Precautions

• Correct Input Voltage: Ensure the supplied DC input voltage (24 VDC nominal) is strictly within the specified range (18-30 VDC for start, 12-30 VDC for run). Incorrect voltage can damage the module.

• Power Capacity: Do not exceed the maximum total output power of 40 Watts. Also, observe the individual power limits for the 5.1 VDC and 3.3 VDC outputs. Overloading will cause the power supply to shut down.

• Wiring: Adhere strictly to the wiring diagrams in the manual. Use the specified wire gauges (14 AWG to 18/22 AWG) and ensure correct polarity and secure connections to the screw terminals. Proper grounding is essential.

• Environmental Conditions: Install the module within its specified operating temperature and humidity ranges. Avoid areas with excessive vibration, direct sunlight, or corrosive atmospheres.

• Cooling: Ensure adequate ventilation around the module, especially in crowded control cabinets, as maximum output power can be derated at higher ambient temperatures.

• Fault Recovery: Note that in fault conditions (like overload), this power supply often "latches OFF." Input power must be cycled (turned off and then on again) to clear a latched fault and restart the power supply.

• Redundancy: This specific model (IC695PSD040F) does not support power supply redundancy. If redundancy is required, a different power supply module or system design approach would be necessary.

• ESD Protection: Always observe electrostatic discharge (ESD) precautions when handling the module to prevent damage to sensitive electronic components.
