Penerangan
Product Overview
The Allen-Bradley 1794-OM8 is a Flex I/O digital AC output module with 8 nonisolated outputs. It operates at 240V AC nominal output voltage with a 4.0A output current rating. Weighing approximately 0.3 kg, the module fits inside the terminal bus, connecting field devices to the I/O bus. Modules can be inserted or removed under power since no direct wiring attaches to the I/O module, saving commissioning time and eliminating system restart inefficiency.

Installation Guide
Snap the module onto a DIN rail for mounting. Use the 1794-TBNF or 1794-TBN terminal base unit for field wiring connections. The module supports insertion and removal under power since no direct wiring attaches to the I/O module itself. Verify output loads do not exceed 500 mA per output or 4A per module. Confirm output voltage remains within the 159-264V AC on-state range. Maintain 0-55°C operating temperature and 5-95% non-condensing humidity.
Engineering Advantages
The 1794-OM8 supports hot-swap removal and insertion, eliminating system restart downtime during maintenance. Eight nonisolated outputs in a single module reduce panel space requirements. Multiple communication options (ControlNet, DeviceNet, EtherNet/IP, Universal Remote I/O) enable flexible network integration. The 250V continuous isolation rating protects the backplane. XT versions are available for extreme environment operation, reducing panel and maintenance costs.
Technical FAQs
Q1: How many outputs does the 1794-OM8 provide?
A1: This module includes 8 nonisolated AC outputs with 240V AC nominal voltage and 4.0A module current rating.
Q2: Can the module be removed while power is on?
A2: Yes, modules can be inserted or removed under power since the I/O module has no direct wiring, saving commissioning time.
