The 1746-OA16 is a Digital AC Output Module manufactured by Allen Bradley/Rockwell Automation as part of the SLC 500 series, and it operates on an input voltage of 85 – 265 volts AC at a frequency 47 – 63 hertz. This module has 16 outputs on 8 points per common group. It operates on a backplane current load of 0.37 amperes at 5 volts DC with a maximum signal delay of 1 millisecond when it’s in ON-state and 11 milliseconds for OFF-state. The 1746-OA16 module features a maximum continuous current of 0.5 amperes per point and 8 amperes per module at 30 degrees Celsius as well as of 0.25 amperes per point and 4 amperes per module at 60 degrees Celsius. This module is designed for general-purpose use with SLC 500 systems of 120 – 240 volts AC of outputs. It collects and stores analog data that is digitally-converted in the data image table from which it is retrievable by all the fixed and modular SLC 500 processors. Additionally, it supports the connections up to 8 actuators or sensors. Allen Bradley 1746-OA16 Digital AC Output Module comes with detachable terminal blocks that can eliminate the need for disconnecting wires when replacing any module. It also comes with a filter circuitry as well as an optical coupling for the reduction of signal noise. The output values of this module can be accessed through the SLC 500 processors by using the Ladder Logic. For troubleshooting, it’s even easier with the LED indicators which show the output status values. The 1746-OA16 module is designed and intended for use in environments with a temperature range of 0 – 60 degrees and non-condensing relative humidity of 5 – 95 percent.

The Allen-Bradley 1746-OA16 Digital AC Output Module is equipped with a NEMA standard ICS 2-230 to combat noise and offer a quieter output. The vibration when this product is operating also has some interesting statistics. The displacement of the device caused by vibration is 0.015 inches at a 5 (five) to fifty-seven (57) hertz, frequency range. The acceleration of the device is 2.5 g at the frequency range of 57 (fifty-seven) to 2000 (two thousand) Hz, or hertz. Additionally, this device this emits a shock when it is operating.

The Allen-Bradley 1746-OA16 has a voltage category of one hundred and twenty (120) to two hundred and forty (240) volts alternating current signal input. The number of outputs for this device is sixteen (16) and it has eight (8) points per common. This Digital AC Output Module has an operational voltage range of eighty-five (85) to two hundred and sixty-five (265) volts alternating current, or AC. This voltage comes due to a frequency range of forty-seven (47) to sixty-three (63) hertz. The backplane current consumption of the Allen-Bradley 1746-OA16 is 0.370 amperes at five (5) volts direct current, or DC. The signal delay with a max resistive load is 1 (one) millisecond when it is on and 11 (eleven) milliseconds when the device is off. The maximum off-state leakage is 2 milliamperes. 

The minimum load current of this output module is ten (10) milliamperes. The current per point when continuous is 0.50 amperes at 30 °C, or 86 °F, and 0.25 amperes at 60 °C, or 140 °F. The continuous current per module at maximum is 8.0 amperes at 30 °C, or 86 ºF, and 4.0 amperes at 60 °C, or 140 °F. The on-state voltage drop is a maximum of 1.50 volts at 0.50 amperes. The surge current per point is a maximum of 10.0 amperes for 25 milliseconds.
