I am listing this because it is no longer needed. This is a set of expansion units for the Keyence KV Nano series. [Items included] KV-EP02 x 1 KV-NC32ET x 5 KV-NC32EX x 3 KV-NC4AD x 2 [Condition] I purchased it used, and it was working correctly until it was removed. Power and basic operation have been confirmed. As this is a used item, please understand that there may be minor scratches and signs of use. [Notes] - A CPU unit is required for use. - Individual sales are also possible, so please comment if you are interested. - If there are any initial defects after purchase, please contact me via transaction message and I will respond. I strive for smooth transactions. Thank you.
