Allen Bradley 1794-OB8EPXT Flex I/O-XT Output Module

Product Introduction

The Allen-Bradley 1794-OB8EPXT Flex I/O-XT Output Module is a high-performance distributed I/O module designed for extended temperature environments. Part of the Flex I/O-XT series, this module provides 8-point 24 VDC sourcing outputs in a compact, DIN-mountable package, making it ideal for remote I/O applications in harsh or space-constrained industrial settings.

The outputs are electronically fused, providing enhanced protection against short circuits and overload conditions. Its open-style construction, combined with an IP20 rating, ensures reliable operation while allowing flexible installation inside control cabinets or enclosures. The extended operating temperature range from -20°C to +70°C makes it suitable for challenging industrial environments where standard modules may fail.

With quick integration into Flex I/O systems and high compatibility with Allen-Bradley controllers, the 1794-OB8EPXT provides a cost-effective and robust solution for distributed control applications.
