Information About 1756-OW16I

The 1756-OW16I is part of the ControlLogix family, designed for use in Rockwell Automation’s ControlLogix chassis-based systems. It functions as a dry-contact relay output module, offering high flexibility by supporting output currents of 1 A at 5–30V DC, 0.5 A at 48V DC, 0.22 A at 125V DC, 1.5 A at 120V AC, and 0.75 A at 240V AC. Each channel is individually isolated, improving noise immunity and ensuring reliable operation in demanding environments. The module has a maximum output delay of 10 ms per transition and a switching frequency of up to one operation every three seconds at rated loads. It includes features such as scheduled outputs and configurable response during program or fault mode (Hold Last State, On, or Off). With backplane current consumption of 150 mA at 5.1V and minimal current draw at 24V, its overall power dissipation is 4.5 W at 60 °C. The 1756-OW16I is compatible with removable terminal blocks (1756-TBCH or 1756-TBS6H), allowing easier wiring and maintenance.

Key Features:

  • Output Channels: Sixteen (16) individually isolated relay outputs with Normally Open (N.O.) contact form.
  • Operating Voltage: Supports wide ranges of 5–125V DC and 10–240V AC for diverse applications.
  • Output Current Ratings: Delivers 1 A @ 5–30V DC, 0.5 A @ 48V DC, 0.22 A @ 125V DC, 1.5 A @ 120V AC, and 0.75 A @ 240V AC.
  • Switching Frequency: Rated at 0.3 Hz (one operation every three seconds) at full load with mean contact bounce of 1.2 ms.
  • Output Timing: Maximum ON-to-OFF and OFF-to-ON delays of 10 ms per channel.
  • Fault/Program Response: Configurable to Hold Last State, turn Off, or remain On during fault or program mode.
  • Backplane Requirements: Draws 150 mA @ 5.1V DC and 2 mA @ 24V DC, with 4.4–4.5 W maximum power dissipation.
  • Installation: Supports removable terminal blocks (1756-TBCH, 1756-TBS6H) for simplified wiring and replacement.

The 1756-OW16I delivers the flexibility, durability, and reliability required for industrial control applications involving AC and DC load switching.

Frequently Asked Questions about 1756-OW16I
Question: What is the primary function of the 1756-OW16I module?
Date Update:03/06/2025
Answer:

The Allen-Bradley 1756-OW16I is a ControlLogix discrete output module designed to interface with electrical actuators and devices through dry contact relay outputs. It is used to control loads such as indicator lights, solenoids, and relays that require voltage isolation and switching flexibility. Each of the 16 output channels is individually isolated, allowing for independent switching and greater application safety. The module supports both AC and DC voltages, making it suitable for mixed-load industrial applications.

Question: What is the switching delay time of the 1756-OW16I?
Date Update:03/06/2025
Answer:

The 1756-OW16I has a switching delay time of up to 10 milliseconds for both ON-to-OFF and OFF-to-ON transitions. This delay is due to the mechanical nature of the relay contacts used in the module. While this is slower than solid-state modules, it is typically acceptable for most general-purpose control tasks. The delay ensures reliable contact operation and prevents bouncing-related errors.

Question: What removable terminal blocks are compatible with the 1756-OW16I?
Date Update:03/06/2025
Answer:

The 1756-OW16I is compatible with the 1756-TBCH and 1756-TBS6H removable terminal blocks (RTBs). These terminal blocks allow for easy installation and maintenance without disconnecting field wiring. RTBs provide secure wiring connections for each output point, maintaining reliability during long-term industrial operation. Using the correct RTB ensures proper signal delivery and system integrity.

Question: What are the dimensions and weight of the 1756-OW16I module?
Date Update:03/06/2025
Answer:

The Allen-Bradley 1756-OW16I has a standard ControlLogix module size that typically measures approximately 142 x 35 x 145 mm (5.6 x 1.4 x 5.7 inches), not including the removable terminal block (RTB). Its weight is approximately 320 to 400 grams (0.7 to 0.9 pounds) depending on the terminal block type used. This compact size allows for easy integration into ControlLogix chassis without requiring excessive panel space. Proper spacing must still be maintained around the module to allow for ventilation and safe access.

Question: Is the 1756-OW16I module still in production?
Date Update:03/06/2025
Answer:

Yes, the Allen-Bradley 1756-OW16I is still in active production by Rockwell Automation and remains a current product in the ControlLogix platform lineup. It continues to be supported in new installations and is included in the latest hardware configuration libraries in Studio 5000 software. Users can order it through official distributors and system integrators. However, it’s always recommended to check the Rockwell Automation Lifecycle Status tool for updates on its availability.
