Allen-Bradley 1790D-T16BV0 | Universal DC Input Base Block

Module Overview

The Allen-Bradley 1790D-T16BV0 simplifies industrial automation by offering 16 universal input points. It supports both sinking and sourcing inputs, which makes it highly versatile. Furthermore, its robust isolation capabilities ensure reliability even in demanding environments. For operators seeking efficiency, this module delivers exceptional performance and adaptability.

Compliance Information

To ensure compliance with the CE Low Voltage Directive (LVD), you must power the DeviceNet network and output devices with a source that meets Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV) standards. Additionally, for UL compliance, always use a source adhering to Class 2 or Limited Voltage/Current requirements. These standards not only promote safety but also enhance operational reliability.
