Product Overview

The IC695PSD040B is a high-efficiency DC power supply module designed specifically for the PACSystems RX3i universal backplane. It converts a 24 VDC nominal input into the required internal bus voltages to operate CPU and I/O modules. Positioned in Slot 0 of the backplane, this module provides a compact, reliable power solution for standalone automation systems.

We supply this unit as a 100% Brand New original component, ensuring optimal performance and factory-certified reliability for long-term system stability.

Technical Specifications

Engineering Advantages

Compact Power Distribution
The IC695PSD040B provides dual-rail output voltages (5.1V and 3.3V) directly to the backplane, eliminating the need for additional bus wiring for individual RX3i components.

Ride-Through Protection
With a 10 ms holdup time, this module prevents system resets during brief power fluctuations, offering stability during voltage drops or brownout conditions.

Auxiliary Power Output
It includes a dedicated 24 VDC output terminal to power external relay circuits or field devices, simplifying wiring and reducing the need for additional power supplies.

Daisy-Chain Capability
Two IC695PSD040B units can be connected in a daisy-chain configuration for extended power distribution, though this does not increase the total wattage capacity for the backplane.

Seamless RX3i Integration
Designed for optimal thermal dissipation and secure mechanical fit, the IC695PSD040B fits perfectly into Slot 0 of the PACSystem RX3i backplane, ensuring seamless operation.

FAQs

Does this module support redundant power configurations?
No, the IC695PSD040B does not support redundant power or increased capacity modes. For power demands exceeding 40 Watts, you will need to distribute modules across separate backplanes, each with its own power supply.

Can I use this power supply in any slot on the backplane?
No, it must be installed into Slot 0 of the RX3i Universal Backplane to properly interface with the power distribution traces.

What happens if the input voltage drops to 15 VDC after the system is running?
The module will continue to operate, as the "Run" requirement is 12-30 VDC. However, the system requires at least 18 VDC to initiate the "Start" sequence.

Is this unit compatible with AC input?
No, this module accepts only DC input (24 VDC nominal). For AC applications, you will need to select an AC-specific power supply from the RX3i series.
