Information About 1756-OA16

The 1756-OA16 is part of the ControlLogix I/O family, offering 16 fused output points arranged in two groups of eight. Each channel supports up to 0.5 A at 60 °C, with a total module rating of 4 A. It requires a 1756-TBSH or 1756-TBNH removable terminal block for wiring and can be installed in chassis models 1756-A4, A7, A10, A13, or A17. The module consumes 400 mA at 5.1 VDC and 2 mA at 24 VDC, dissipating up to 6.5 W at full load. Key protections include per-point fusing, on/off-state detection, and fault reporting tags such as FuseBlown (fuse failure) and FieldPwrLoss (loss of field power). Response times are 9.3 ms from OFF to ON and 11 ms from ON to OFF, suitable for general-purpose AC control. The module operates from 0…60 °C, with storage limits of –40…85 °C, and is rated for 5–95% RH non-condensing. With pilot duty rating and interposing relay recommendations for heavy inductive loads, the 1756-OA16 ensures long service life in demanding automation systems.

Key Features:

  • Design: 16-point AC output module for ControlLogix systems.
  • Output Voltage: Operates at 74–265 VAC, 47–63 Hz.
  • Output Current: 0.5 A per point, 2 A per group, 4 A total at 60 °C.
  • Minimum Load: 10 mA per output channel.
  • Response Times: 9.3 ms OFF→ON, 11 ms ON→OFF.
  • Power Dissipation: 6.5 W max (22.17 BTU/h).
  • Backplane Requirements: 400 mA @ 5.1 VDC, 2 mA @ 24 VDC.
  • Protection: Integrated channel fuses, on/off-state monitoring, fault tags (FuseBlown, FieldPwrLoss).
  • Indicators: Per-channel LED status indicators.
  • Compatibility: Works with all ControlLogix processors and communication modules.
  • Mounting: Installs in local or remote chassis with removable terminal blocks (1756-TBSH or 1756-TBNH).

The 1756-OA16 delivers safe and reliable AC output control, making it a versatile solution for industrial automation systems built on the ControlLogix platform.

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.
