Information About 1794-IB16

The Allen-Bradley 1794-IB16 is a Sixteen (16) channel 24VDC Discrete input module. This module is part of the 1794 Flex IO product family which is primarily used to implement distributed IO solution. With distributed I/O architecture, I/O modules may be installed near the source of the signal or the driven load. This significantly reduces cable runs thus, reduces overall installation costs. It also simplifies maintenance and contributes to overall increase in the control system uptime.

The 1794-IB16 support standard DIN rail mounting or direct panel mounting. This module is used with terminal base where signal wirings are terminated. Compatible terminal bases are 1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, 1794-TB37DS. Additionally, the1794-IB16 require use of a communication adapter for transferring I/O data to the partner scanner module or controller. Compatible communication adapters are DeviceNet communication adapter with catalog number 1794-ADN, Remote I/O communication adapter with catalog number 1794-ASB, Ethernet communication adapter with catalog number 1794-AENT, Profibus communication adapter with catalog number 1794-APB and ControlNet communication adapter with catalog number 1794-ACN.

The 1794-IB16 has a current draw of 30 mA @ 5V DC. The individual input channels are rated10 to 31.2 VDC with nominal input voltage of 24VDC and supports sink wiring configuration. Each channel has a minimum On-state voltage of 10VDC and maximum of 31.2VDC while the maximum OFF-state voltage is 20VDAC. It has a power dissipation of 3.5 W @ 31.2V DC and Thermal dissipation of 11.9 BTU/hr @ 31.2V DC.

The 1794-IB16 module has 16 current sinking inputs with 24V DC nominal On-State voltage, 10-31.2V DC On-State voltage range, and 1.5mA minimum Off-State current. It has a maximum power dissipation of 6.1W at 31.2V DC. Terminal base units compatible with this module are the 1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, 1794-TB37DS.

This module supports DIN rail or panel mounting and supports various communication adapters such as ControlNet, DeviceNet, EtherNet/IP, and Universal Remote I/O. The 1794-IB16 module has 16 yellow LEDs as status indicators for each channel. LEDs indicate corresponding input device and output signal. It also has D and XT versions of standard modules for diagnostics and extreme environments which reduces panel and maintenance costs. It has a 0 - 55 °C (32 - 131 °F) operating temperature and a 5 - 95% noncondensing relative humidity.

Frequently Asked Questions about 1794-IB16
Question: What is the primary function of the 1794-IB16 module?
Date Update:30/05/2025
Answer:

The 1794-IB16 is a discrete input module from the Flex I/O family that provides sixteen (16) current-sinking input channels. Its primary role is to monitor digital signals from field devices such as push buttons, sensors, and switches. It is widely used in distributed control architectures where I/O modules are mounted close to machines or processes. This reduces wiring complexity and improves system maintainability.

Question: What voltage and current ratings are supported by the 1794-IB16 input channels?
Date Update:30/05/2025
Answer:

Each input channel supports a voltage range of 10 to 31.2 VDC, with a nominal voltage of 24 VDC. The input current per channel ranges from 2.0 mA to 12.0 mA. These specifications make the module suitable for interfacing with a wide range of standard industrial sensors and switches. Off-state voltage must not exceed 5 VDC, and off-state current is limited to 1.5 mA.

Question: What are the dimensions and weight of the 1794-IB16 module?
Date Update:30/05/2025
Answer:

The Allen-Bradley 1794-IB16 has a compact and lightweight design, typical of the Flex I/O series. Its dimensions are approximately 87 x 94 x 69 mm (3.4 x 3.7 x 2.7 inches), making it suitable for dense installations on DIN rails. The module weighs about 227 grams (8 ounces), which allows easy handling and mounting even in space-constrained enclosures. Its small footprint helps reduce the overall size of distributed I/O panels.

Question: What are the compatible terminal base units for wiring the 1794-IB16?
Date Update:30/05/2025
Answer:

The 1794-IB16 is compatible with multiple terminal bases including 1794-TB3, TB3S, TB3K, TB3SK, TBKD, and TB37DS. These bases provide the interface for connecting field wiring to the module. The specific terminal base selection depends on the application, such as whether screw terminals or spring-clamp terminals are preferred. Terminal base choice also affects wire gauge and installation flexibility.

Question: Is the 1794-IB16 still in production and widely supported?
Date Update:30/05/2025
Answer:

Yes, the 1794-IB16 remains an actively supported product within the Allen-Bradley Flex I/O family. It is used in many legacy and modern distributed I/O systems and is compatible with various communication adapters. Its reliability and flexible mounting make it a popular choice in both new and retrofit automation projects. Rockwell Automation continues to provide support, documentation, and spare parts for this module.
