Klockner-Moeller PS3-DC 24VDC Programmable Controller

Description

3. Key Technical Specifications

4. Product Introduction & Supply Chain Strategy

The Klockner-Moeller / Eaton PS3-DC is a compact programmable controller from the SucoControl PS3 family. It was designed as an economical solution for low- to medium-complexity machines, offering a balanced mix of digital and analog I/O, a real-time clock, and high-speed counting capability in a single compact package.

These controllers were widely installed in industrial machinery and are still found in service worldwide. Because the PS3 platform is no longer in active production, genuine New Surplus units are valuable for maintaining existing systems. Securing new, unused controllers helps avoid the reliability risks of aged or refurbished modules and supports lower total cost of ownership by minimizing unplanned downtime.

5. Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)
Lock out and tag out all power sources. Record the existing controller’s program, I/O mapping, and any Suconet or communication settings. Photograph wiring and terminal connections. Wear ESD protection when handling the unit.

Stage 2: Removal
Power down the system completely. Disconnect all input, output, power, and communication wiring. Unmount the existing PS3-DC from its panel or DIN-rail location.

Stage 3: Installation (Clone & Seat)
Mount the new PS3-DC securely. Reconnect power, digital and analog I/O, and any fieldbus wiring exactly as documented. Observe correct polarity on the 24 VDC supply and I/O circuits.

Stage 4: Power-On & Testing
Restore control power. Load or verify the application program using the appropriate programming tool (PRG3 or Sucosoft). Test digital and analog I/O points under controlled conditions and confirm real-time clock and counter operation before returning the machine to production.

6. Firmware/Software Versions & Upgrade Notes

The PS3-DC is programmed with the PRG3 handheld programmer or Sucosoft S30-S3 software via the appropriate interface cable. Always back up the existing program before replacement.

Confirm that the replacement unit accepts the original program without modification. After installation, verify I/O addressing, analog scaling, and any communication parameters. Incorrect program transfer or mismatched hardware variants can prevent proper machine operation.

7. Frequently Asked Questions (FAQ)

Is this controller new or refurbished?
This is Brand New Surplus / Original New. It has never been installed in a system and is not a repaired or rebuilt unit.

Why is New Surplus preferred for legacy PLCs?
Compact controllers from this era often operate in continuous-duty machines. New Surplus units retain full expected service life and avoid the risks of aged memory, degraded power components, or undocumented prior use common with refurbished units.

What I/O does the PS3-DC provide?
It offers 16 digital inputs, 16 digital outputs, 4 analog inputs (0–10 V), 1 analog output (0–10 V), a real-time clock, and high-speed counter capability.

How is the PS3-DC programmed?
Programming is performed with the PRG3 handheld device or a PC running Sucosoft software and the appropriate interface cable.

Is the PS3 series still supported?
The product is discontinued and was succeeded by the PS4 series and later Eaton platforms. Support is limited to remaining New Surplus inventory and specialized service providers.

What is the main risk of using a refurbished unit?
Aged components, memory corruption, or degraded I/O circuits can lead to intermittent faults, program loss, or complete controller failure.

What warranty is provided?
New Surplus units typically carry a 1–2 year warranty covering defects in materials and workmanship under normal industrial operating conditions.
