SIEMENS PXA40-T terminal

Product Detailed Description:

The Siemens PXA40-T is a specific terminal within the PXA series of the PXC modular terminal system. The PXC system is designed for efficient and flexible signal distribution and processing in control cabinets and on machines. The “PXA” series typically refers to terminals equipped with active components, such as signal conditioners or amplifiers, which process the electrical signals before they are passed on.

The “40” in the designation likely indicates its specific function or signal type, and the “T” suffix might denote a particular version, configuration, or terminal type (e.g., terminal block style). The PXA40-T is designed for reliable signal transmission, often featuring high signal quality, robust construction, and easy integration into the modular PXC system. It allows for the direct connection and processing of various sensor or actuator signals within a compact and organized terminal block arrangement.

Product Parameters:
