Product Procurement & Installation Guide
The 1794-OF8IH delivers eight isolated HART analog outputs with 16-bit resolution. You get precise control for 0-20 mA or 4-20 mA loops. This module eliminates jumpers and switches for quick setup. Procurement managers value its factory calibration and reliable performance.
8 isolated outputs support independent programming of current ranges. Each channel uses a 16-bit digital-to-analog converter. The conversion rate is just 10 ms. You achieve seamless integration with Rockwell Automation Flex I/O systems.
Installation requires a compatible terminal base like the 1794-TB3 or 1794-TB3S. Rotate the keyswitch to position 4 to lock the module. Wiring depends on your chosen terminal base type. The module draws power from the FlexBus at 80 mA at 5V DC.
The 1794-OF8IH supports HART pass-through messages with one or two connections. Each connection queues up to eight messages. This allows direct communication with HART field devices. Detect lead breakages and overrange or underrange current alarms easily.
Power dissipation reaches a maximum of 5.0 W at 24V DC. Thermal dissipation is 17.06 BTU/hr. The module operates from 32 to 131 degrees Fahrenheit. It requires no external power supply, simplifying cabinet layout.
Engineers appreciate the dedicated HART data register. It stores device, communication, and primary value in IEEE 754 format. This ensures accurate loop status monitoring. The 1794-OF8IH is a smart choice for demanding process applications.
