The Omron NX-TBA082 Machine Automation Controller System Unit provides an 8-terminal interface for terminal expansion within NX control architectures. A/B terminal number indications support connection identification, while a dedicated ground terminal marking provides the specified reference for system wiring. The unit supports a terminal current capacity of 10 A and is designed for use with the NX-TBC082 terminal block. This combination provides a structured connection arrangement for modular NX installations. The NX-TBA082 supports terminal distribution and wiring organization as part of the NX platform. Its system-expansion role complements the PLC rack and expansion range within Omron machine automation systems.
