Information About 1756-OW16I

The Allen-Bradley 1756-OW16I is a Sixteen (16) channel discrete output module that is part of the ControlLogix automation platform. This module is a relay output module with contact form of Normally Open (N.O.) with individual isolation. This module may also be termed as a dry contact output module which is compatible to be operated at voltage ranges of 5-125VDC and 10-240VAC.

The 1756-OW16I delivers output current ratings of 1 A @ 5-30V DC; 0.5 A @ 48VDC; 0.22 A @ 125VDC; 1.5 A @ 120VAC, 50/60 Hz and 0.75 A @ 240VAC, 50/60 Hz. This module has a pilot duty rating of C300/R150.

Each output channel has a maximum output delay time of 10 ms for both signal transitions. It draws 150 mA current from the backplane @ 5.1 VDC and 24VDC with total backplane power draw of 4.4 Watts.

The 1756-OW16I has a maximum switching frequency of One (1) operation every Three (3) seconds or (0.3 Hz at rated load) with mean bounce time of 1.2 ms. Each of the output contacts are expected to operate up to 300 kHz when used with resistive loads and 100 kHz when used with inductive loads. Additionally, this module supports scheduled outputs and may be configured to Hold last state, On or Off during when FAULTED with Off as default setting. Similarly, output states may also be held at last state, with OFF as default setting during PROGRAM mode. This module is shipped with a Removable Terminal Block (RTB). Applicable RTB for use with this module are 1756-TBCH and 1756-TBS6H.

The 1756-OW16I’s output delay time for both ON to OFF and OFF to ON is 10 milliseconds and it draws a backplane current of 150mA at both 5.1 Volts and 24 Volts DC and it has a total backplane power of 4.4 Watts. It has a thermal dissipation of 15.35 BTU/hour and dissipates 4.5 Watts at 60 degrees Celsius. Each output can accommodate a minimum current load of 10mA and a current leakage of 1.5 mA per point. The 1756-OW16I contact module has an initial contact impedance of 100 Ohms at 6V, 1A and it has a load-dependent switching frequency of 0.3 Hertz. It has a mean bounce time of 1.2 milliseconds with an expected contact life of 300 kHz resistive and of 100 kHz inductive. The 1756-OW16I has a scheduled output with a 16.7 second synchronization time with respect to Coordinated System Time (CST), and it has a circuit isolation voltage of 250 Volts with a basic insulation type tested at 1350 Volts AC for 2 seconds between outputs-to-backplane and output-to-output. The 1756-OW16I has a designated T4 North America temperature code and an open enclosure. Its operational temperature ranges between 0 and 60 degrees Celsius at a humidity of 5 to 95% without condensation.

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.
