Information About 1756-OA16

The 1756-OA16 module is a Sixteen (16) point digital output module from the ControlLogix Series of modules made by the Allen-Bradley. The output voltage range of this digital module is 74 to 265 Volts AC at 46 to 63 Hertz. The output current rating per point, per group, and per module are 0.5 Amperes at 60 degrees Celsius, 2 Amperes at 60 degrees Celsius, and 4 Amperes at 60 degrees Celsius, respectively. The minimum load current is 10 mA per point. Furthermore, the backplane current of 1756-OA16 is 400 mA at 5.1 Volts DC and 2 mA at 24 Volts DC, constituting a total backplane power dissipation of 2.1 Watts. Moreover, the maximum power dissipation and thermal dissipation ratings are 6.5 Watts at 60 degrees Celsius and 22.17 BTU/hour, respectively. The 1756-OA16 also supports 2 removable terminal blocks, the 1756-TBSH and the 1756-TBNH.

The 1756-OA16 module can be set to different operating or non-operating states, including the on-state, off-state, and last state (a reset function that resets a module that was suddenly powered down to the last operating state that it was in). The maximum voltage drop in the on-state is 1.5 Volts at 0.5 Amps and 5.7 Volts at a load current of less than 50 mA. On the other hand, the maximum leakage current in the off-state is 3 mA per point. The 1756-OA16 also features an output delay time for the off to on state which is 9.3 milliseconds at 60 Hertz, and one for the on to off state is 11 milliseconds at 50 Hertz. To alert the users if the point or group fuse is blown, the 1756-OA16 module will indicate this with the fault word tag name FuseBlown. Another fault word tag name is FieldPwrLoss which indicates a loss of field power to the modules output points. The 1756-OA16 can operate in a temperature range of 32 to140 degrees Fahrenheit and it can be stored or transported at a temperature range of -40 to 185 degrees Fahrenheit. It can operate and be stored in an environment with a relative humidity range of 5 to 95%, non-condensing.

This module is mounted to any compatible ControlLogix chassis 1756-A4, 1756/A7, 1756-A10, 1756-A13 and 1756-A17. It also requires a Removable Terminal Block (RTB) that serves as the termination points of I/O signals. It may be installed in local or remote I/O ControlLogix chassis. Local ControlLogix chassis is where the ControlLogix processor is installed while remote I/O chassis refers to a chassis that communicates to the local chassis through a communication module. This chassis may also be referred to as Remote I/O or distributed I/O.

This module has a Pilot duty rating of 0.5 A. It can energize or trigger inductive loads such as Solenoid actuated devices which may be valves, cylinders and other devices. It may also be used to activate relays even magnetic contactors however, if the module is planned to energize higher inductive loads with high inrush currents, it is recommended to install an isolation such as an interposing circuit to protect the module.

This module is compatible with any ControlLogix processor. It is also compatible with any ControlLogix communication module including encompass partner modules. It may also work along a GuradLogix module.

This module has front panel indicators that provide status of each channel. Whenever a channel is supplied with an appropriate signal, the dedicated LED indicator will be activated to confirm that the signal is received by the module.

Frequently Asked Questions about 1756-OA16
Question: What is the 1756-OA16?
Date Update:28/05/2025
Answer:

The 1756-OA16 is a 16-point analog output module from the ControlLogix series by Allen-Bradley. It is used to provide analog output signals to control devices like motors, valves, and actuators. It supports both voltage and current output ranges, making it versatile for various industrial applications.

Question: Why should I replace a blown fuse?
Date Update:28/05/2025
Answer:

Replacing a blown fuse is essential to restore the proper functionality of the electrical system. A blown fuse means that the circuit is no longer protected from overcurrent, which can lead to further damage or even pose a fire risk if not replaced promptly.

Question: How do I know if a fuse is blown?
Date Update:28/05/2025
Answer:

You can tell if a fuse is blown by inspecting it visually. For glass fuses, you may see a broken filament or the glass might be blackened. For other types of fuses, such as cartridge fuses, you may notice visible signs of damage or discoloration on the metal ends. Additionally, if the device or circuit isn't working, it could be due to a blown fuse.

Question: Can I use any fuse to replace a blown one?
Date Update:28/05/2025
Answer:

No, you must replace the blown fuse with one that matches the exact specifications of the original. This includes the voltage rating, current rating, and fuse type (e.g., glass, cartridge, blade). Using the wrong fuse can damage the system or cause it to malfunction.

Question: Can I replace a fuse while the system is powered on?
Date Update:28/05/2025
Answer:

No, you should always power off the system before replacing a fuse. Replacing a fuse while the system is powered on could lead to electrical shock or damage to the system. Always ensure the equipment is powered off and properly isolated before working on it.
