ABB TU516 I/O Terminal Unit

Description

The ABB TU516 I/O Terminal Unit is a dedicated industrial connectivity component designed for signal transmission and control in automation systems, with a specific part number 1SAP212000R0001 and specification code 330180-50-00. As part of ABB’s I/O terminal unit lineup, it is powered by 24V DC and features integrated spring connection terminals for secure, tool-free wiring of input and output devices. This unit functions as an I/O module base, facilitating reliable connections between field devices and control systems to support seamless data and signal transfer. It is compatible with ABB’s S500 I/O system, a cost-effective automation platform suitable for a wide range of industrial applications, and works alongside related I/O modules such as analog input/output units, digital input/output units, and communication modules. Unlike the similar TU515 model which uses screw terminals, the TU516’s spring terminals enable faster installation and maintenance. It is engineered to integrate with various industrial control equipment, making it ideal for general-purpose automation scenarios requiring efficient I/O signal management.
