The Keyence KV-8000A serves as the central processor for the KV-8000 series building-block PLC. Specifically, it pairs a 64 MB CPU memory with a program capacity of roughly 1,500 k steps. Machine builders often select it for high-speed lines, packaging equipment, and complex assembly stations.
Additionally, the unit executes basic instructions in a minimum of 0.96 ns and applied instructions in a minimum of 5.75 ns. Double-precision floating-point operations complete in a minimum of 58 ns. Such speed supports precise motion sequencing and fast data handling.
Furthermore, the KV-8000A CPU unit includes a built-in operation recorder function. This feature captures device and program behavior without extra hardware. Therefore, engineers can trace faults quickly during commissioning and maintenance.
The CPU memory capacity is 64 MB, and the program capacity reaches approximately 1,500 k steps. First, the unit supports expanded ladder, KV Script, and mnemonic programming. Second, instruction execution speed stays at a minimum of 0.96 ns for basic instructions. Third, the max I/O points reach 3,072 for expansion via backplane modules.
Built-in Ethernet ports (RJ-45) support EtherNet/IP communication. Moreover, the CPU acts as an OPC UA server and an FTP client/server. KV STUDIO software connects directly for programming and monitoring. In addition, communication expansion is possible through backplane modules such as the KV-XL202 RS-232C serial unit. However, no other built-in fieldbus ports are present.
The system accepts up to 16 installable units with KV-8000/7000 expansion. With a KV-EB1 extension, that figure rises to 48 units. Hence, the platform scales from compact machines to large distributed systems.
Supply voltage is 24 VDC (-15%/+20%) with KV-8000/7000 expansion only. When paired with KV-5000/3000 expansion, the unit accepts 24 VDC (±10%). Internal current consumption stays at 400 mA or less.
Operating temperature ranges from 0 to +55 °C without freezing, using KV-8000/7000 expansion. Storage temperature spans -25 to +75 °C. Relative humidity stays between 5 and 95% RH without condensation. Besides, no official protection rating is available. The CPU weighs approximately 0.34 kg, and the KV-B1 battery adds about 0.01 kg.
Mount the KV-8000A on the base unit and secure it with the fixing screws. First, confirm the power supply matches 24 VDC and wire the terminals with correct polarity. Next, attach expansion modules to the backplane in the planned order. Then, connect the Ethernet cable for programming and network access. After that, load the program through KV STUDIO and run a test cycle. Finally, install the KV-B1 battery to protect retained data during power loss.
