Huge I/O Capacity

Let's start with high-density I/O modules - up to 64 inputs or outputs per module, installed in an 11 slot base, and you've got over 700 I/O in a single rack! Add up to 4 local racks to your local base group, and the possible I/O total grows to over 3500 I/O points. Still need more? Add up to 16 Remote Slave racks, each with its own set of 4 local expansion racks and the number is truly staggering - well over 59,000 I/O points.

What about the cost?
Every P3-550 CPU comes with built-in local and remote expansion ports. The Productivity3000 uses standard (low-cost) USB (A-B) cables (included) for the local expansion, and standard (low-cost) Ethernet cables for the Remote connectivity. The P3-EX Local I/O Expansion Module (required in each local rack) is a true bargain at $72.00. The P3-RS module (required in all remote racks) is also a great value at $449.00. The Productivity3000 is cost-effective at any I/O count!
