Product Overview

The IC693PWR331D provides essential DC power to the PACSystems RX3i or Series 90-30 backplane, converting a 48 VDC nominal input into the regulated voltages required by the CPU and I/O modules. As a high-capacity version, this module delivers increased current output to support larger rack configurations and power-intensive modules.

We supply this unit as 100% Brand New and original equipment, ensuring stable voltage regulation and minimizing downtime caused by power fluctuations.

Technical Specifications

Engineering Advantages

Supports High-Density Configurations
With 30W output capacity, this module can power a fully populated 10-slot baseplate, reducing the need for auxiliary power supplies.

Industrial-Grade Electrical Isolation
Provides strong isolation between the 48 VDC input and PLC logic circuitry, protecting sensitive components from voltage spikes and electrical noise.

Integrated Status Diagnostics
Front-panel LED indicators (PWR) allow quick verification of power health, enabling faster fault isolation during maintenance.

Built-In Communication Interface
The onboard RS-485 port enables direct connection to compatible programmers or HMIs, saving valuable I/O slots otherwise required for communication modules.

FAQs

Can this module be used in a Series 90-30 expansion baseplate?
Yes. It installs in the leftmost slot of both CPU and expansion baseplates within the Series 90-30 system.

Does it support 24 VDC input?
No. The module requires a 48 VDC nominal input (38–56 VDC range). Using 24 VDC will result in an undervoltage condition.

What is the purpose of the 24V isolated output?
It supplies clean, isolated power for input modules or small field circuits, preventing electrical noise from affecting the PLC backplane.

Is it compatible with PACSystems RX3i?
While physically compatible, it is primarily designed for Series 90-30 systems. RX3i applications typically use IC695 series power supplies for optimal performance, though this unit may be used in migration setups.
