Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1794-OB8EPXT is an Allen-Bradley Flex I/O-XT digital DC output module offering eight electronically fused sourcing outputs. It is part of the 1794 Flex-XT platform and installs on a terminal base such as the 1794-TB3 or TB2. It operates within standard control architectures to switch DC loads in industrial automation systems. Its extended environmental rating makes it suitable for installations exposed to more extreme ambient conditions. Part number 1794-OB8EPXT.
Best Suited For
- Flex I/O-XT installations requiring fused DC outputs
- Applications needing extended temperature range (-20 °C…70 °C)
