Yokogawa Electric Corporation TB16A Auxiliary Terminal Block

The Yokogawa TB16A Auxiliary Terminal Block (Model TB16A, TB16*A) is a 16-terminal, screw-terminal interface designed to organize field wiring within Yokogawa control and automation systems. As an auxiliary wiring component, it provides a centralized interface for terminating multiple signals and serves as the connection point between field devices and control modules, with installation options including panel-mounted or placement inside a control enclosure in industrial environments. Commonly found as surplus or used units, the TB16A is intended for signal distribution and termination in manufacturing, process control, and maintenance applications, and is especially useful for retrofit or replacement in older Yokogawa installations.
