OverviewManualsCommon ApplicationsInstallation and Setup
The 1794-IB8 is an 8-channel digital DC input module designed for use within the FLEX™ I/O system. This model features a compact, modular design that plugs into a terminal base, providing a cost-effective way to interface with 24V DC field sensors. It is fully compatible with various FLEX I/O terminal bases,to suit different wiring requirements.
RIUP Capability
Modular Terminal Base Interface
High-speed Input Filtering
Engineered for industrial reliability, the 1794-IB8 operates over a voltage range of 10V to 31.2V DC and features an input filter time of typically 0.25 ms to ensure precise signal capture. The module supports Removal and Insertion Under Power (RIUP), allowing for maintenance and replacement without disrupting the rest of the control system. Each input is a current-sinking type, providing consistent performance in high-speed digital monitoring applications.

To install the 1794-IB8, rotate the module onto the terminal base until the locking arms snap into place. Before applying power, ensure the module is securely seated and the keyswitch on the terminal base is set to the correct position for a digital DC input module. This setup allows for distributed I/O across various networks when combined with a FLEX I/O adapter. Use the status indicators on the front of the module to verify that each of the 8 inputs is correctly sensing the state of its connected field device.
What is the primary function of the Allen-Bradley 1794-IB8 module in a FLEX I/O system?
The 1794-IB8 is an 8-channel digital DC input module that senses ON/OFF signals from field devices. It interfaces with a terminal base and a communication adapter to provide distributed I/O over various networks.
What are the input voltage and current specifications for the 1794-IB8?
The 1794-IB8 operates with a nominal input voltage of 24V DC and an input voltage range of 10V to 31.2V DC. The typical input current is 8 mA at 24V DC, providing consistent signal detection for industrial sensors.
How is the Allen-Bradley 1794-IB8 installed and secured onto the terminal base?
To install the 1794-IB8, you must align the module with the terminal base unit and press firmly to seat the module. The module is secured when the side locking tabs snap into place on the base.
Does the 1794-IB8 support removal and insertion under power (RIUP)?
Yes, the 1794-IB8 is designed for removal and insertion under power (RIUP), allowing you to replace the module without disturbing the rest of the system's operation. However, the external power must be disconnected from the module’s inputs.
What are the input filter time specifications for the 1794-IB8 module?
The 1794-IB8 features an input filter time (Off-to-On and On-to-Off) that is typically 0.25 ms. This fast response time ensures that rapid state changes in field devices are accurately captured by the controller.
