PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-OE8H FLEX I/O Analog Output Module provides process control outputs across industrial automation architectures. This module incorporates eight single-ended output channels. It operates on a nominal supply voltage of 24 VDC. Power is supplied directly across the FLEX I/O backplane interface. Channel-to-backplane electrical isolation protects control hardware from electrical disturbances.
The 1794-OE8H module supports standard HART protocol communication. Field devices connect through electrical terminal bases with full HART pass-through capabilities. LED indicators provide real-time status updates for module power and I/O operational health. The IP20 open-style enclosure mounts directly onto standard DIN rail systems. This design suits indoor process control cabinets and automation environments.
