Omron CPM1A-40CDR-D-V1

The Omron CPM1A-40CDR-D-V1 is a true vintage powerhouse. While the CP1E you looked at earlier is more modern, the CPM1A is the “old reliable” often found in older textile machinery, packaging lines, and marine control panels.

Here is the technical breakdown for your inventory:

⚙️ Technical Specifications

• I/O Count: 40 Total (24 Inputs / 16 Outputs).

• Output Type: Relay (The “R” in the name).

• Power Supply: 24V DC (The “D” at the end). Note: This is different from the AC-powered units we usually see, so it needs a stable DC power source.

• V1 Version: This is the “Enhanced” version which supports faster processing and more instructions than the original CPM1.

• Expansion: Supports up to 3 expansion I/O modules (CPM1W series).

🛠️ Key Details for Buyers

• Marine & Industrial Use: Because it runs on 24V DC, it is very common in battery-backed systems or shipboard automation where AC power might fluctuate.

• Programming Port: It uses a peripheral port that requires a special adapter (like the CIF01) to connect to a PC. If you have that adapter, it adds significant value to a “kit.”

• Mounting: Standard DIN rail mount, but it’s a bit bulkier than modern PLCs.

💰 Market Status (The “Gold” Factor)

• Condition Check: Look at the lithium battery inside. If it’s been sitting in storage for years, the program memory might be gone, but the hardware is usually tank-like and keeps working.

• Surplus Value: Since these are Long Obsolete, they are highly sought after as direct replacements. In the Bhavnagar/Sihor markets, a clean “V1” unit can be priced higher than a newer CP1E simply because it’s harder to find.
