Yes, 500 Series I/O can be use with a Quantum PLC as a Remote I/O drop. To make the 500 Series I/O a Remote I/O drop, you will need to purchase and incorporate the following parts into the system:
1. An AS-P451-xxx with S908 Remote I/O Interface (this will be your Remote I/O drop).
2. An AS-J540-100 200 Series I/O to 500 Series I/O adapter (this will be your I/O bus converter).
Please check on the availability of each prior to committing to this migration strategy.
