Product Summary
The 1794-OA16 Flex I/O AC output module from Allen-Bradley controls sixteen discrete loads. This module switches AC power to devices like contactors and relays. It operates reliably within a voltage range of 74 to 132 VAC. Engineers trust this module for demanding industrial applications.
Theme A: Product Procurement & Buyer Guide
This module solves critical pain points for procurement managers. It offers a high channel density of sixteen outputs in a single unit. This reduces the need for multiple modules, saving panel space. The 1794-OA16 also simplifies inventory management with its broad compatibility.
The module works with ten different terminal base units. These include the 1794-TBN, 1794-TB3, and 1794-TBNF. This flexibility allows you to standardize on one output module across various system designs. You can match the terminal base to your specific wiring and fusing needs.
Application engineers benefit from the module’s robust electrical specifications. Each output channel can handle up to 500 mA at 55 degrees Celsius. The total module output current rating is 4.0 Amps. This provides ample power for energizing multiple industrial loads simultaneously.
The module includes an internal fuse for circuit protection. This built-in fuse is a 2.5 Amp, 150V AC normal blow type. This feature simplifies installation by removing the need for external fusing in many cases. It also protects your downstream equipment from overcurrent faults.
Its key switch position is set to 8 for mechanical alignment. This ensures correct installation with the terminal base and backplane. The module also features 16 yellow status indicators. These LEDs provide immediate visual feedback on the state of each output channel.
Theme B: Step-by-Step User & Installation Guide
Proper installation ensures reliable operation of the 1794-OA16. First, select the correct terminal base for your application. The module is compatible with the 1794-TBN for fused applications. Use the 1794-TB3 for standard screw-clamp terminations.
Mount the chosen terminal base onto a standard DIN rail. Hook the top of the base over the rail and press down. Push the base firmly to lock it into place against the adjacent adapter. Ensure the FlexBus connector engages correctly with the neighboring module.
Next, mount the 1794-OA16 module onto the terminal base. Align the module’s key switch with the base’s keyway. Push the module straight in until it snaps securely into position. This action connects the module to the backplane for power and communication.
Wire your field devices to the terminal base’s screw clamps. The wire size depends on the terminal base you selected. For the 1794-TB3, you can use conductors from 22 to 12 gauge. Strip the insulation to a length of 1.2 mm for a proper connection.
Connect the external AC power supply to the module. The module requires a nominal 120 VAC power source. Ensure the voltage stays within the 74 to 132 VAC range. The output signal delay is only half a cycle for both on and off transitions.
