Description

The 1756-OA16 is a digital output module manufactured by Allen-Bradley for the ControlLogix Series. The voltage category is 120/240 Volts AC at 50/60 Hertz, with an operating voltage range of 74 to 265 Volts AC at 47 to 63 Hertz.

• Operating Voltage Range: 74-265 VAC
• Outputs: 16 Pts, Mechanically fused/group
• Pilot Duty: 0.5 mA
• Current Draw (5.1 Volts): 400 milliamperes
• Current Draw (24 Volts): 2 milliamperes
• Total Backplane Power: 2.1 Watts

The 1756-OA16 can be set to different operating or non-operating states, including the on-state, off-state, and last state. The maximum voltage drop in the on-state is 1.5 Volts at 0.5 Amperes and 5.7 Volts at a load current of less than 50 milliamperes. The maximum leakage current in the off-state is 3 milliamperes per point.
The output delay time from ‘off’ to ‘on’ and ‘on’ to ‘off’ is 9.3 milliseconds at 60 Hertz and 11 milliseconds at 50 Hertz.

The module has a current draw of 400 milliamperes at 5.1 Volts and 2 milliamperes at 24 Volts, and a total backplane power of 2.1 Watts. The module has an isolation voltage of 250 Volts (continuous) with basic insulation type.

The maximum power dissipation is 6.5 Watts at 60 degrees Celsius, and the thermal dissipation is 22.17 BTU/hour.

The module operates in a temperature range of 0 to 60 degrees Celsius and can be stored or transported at a temperature range of -40 to 85 degrees Celsius. It has a relative humidity rating of 5% to 95% (non-condensing) and a vibration of 2 G at 10 to 500 Hertz. Operating and non-operating shock are 30 G and 50 G, respectively.

The module can be mounted to any compatible ControlLogix chassis and requires a removable terminal block (RTB) for termination of I/O signals. The RTB can be either 1756-TBSH or 1756-TBNH. The 1756-OA16 can energize or trigger inductive loads such as solenoid actuated devices, valves, cylinders, and other devices.
