Allen-Bradley 1756-OA16K 16-Point AC Output Module ControlLogix

Product Overview

The Allen-Bradley 1756-OA16K is a high-performance AC output module. It belongs to the ControlLogix series. This module provides 16 discrete output points. It operates at 120-140 Volts AC. The module supports a wide voltage range from 74 to 265 Volts AC. Each output point can handle 0.5 Amps at 60 degrees Celsius. The total module current rating is 4 Amps at 60 degrees Celsius. This makes it suitable for various industrial loads.

This module uses a removable terminal block. You can use either the 1756-TBNH or the 1756-TBSH blocks. This design simplifies wiring and maintenance. The 1756-OA16K has a maximum power dissipation of 6.5 Watts. It draws 400 milliamps from the 5 Volt backplane. The isolation voltage is 50 Volts continuous. The module does not come with an enclosure.

Application Scenarios

You can use this module in many factory automation tasks. It controls AC devices like motors and solenoids. It also works with relays and lamps. The module fits into ControlLogix chassis. It is ideal for discrete manufacturing. Use it for packaging, material handling, and assembly lines. The module handles high inrush currents well. This ensures reliable switching of inductive loads.
