Engineering Advantages
Universal Sinking and Sourcing Flexibility
The 1790D-T16BV0 eliminates complex wiring workarounds by accepting both sinking and sourcing 24V DC signals on the same module. This universal input capability allows engineers to connect diverse field devices—such as PNP and NPN proximity sensors, limit switches, and pushbuttons—without needing separate modules for different sensor types, significantly simplifying inventory and panel design.
Ruggedized for High-Vibration Environments
Built to endure the physical demands of factory floor automation, this input block features a highly durable mechanical design. It withstands operating shock up to 30 g peak and continuous vibration of 5 g across a 10 to 500 Hz frequency range. This ruggedness ensures stable signal acquisition and prevents false triggers in dynamic applications like packaging machinery, conveyors, and automotive assembly lines.
Compact and Scalable Machine-Level I/O
As part of the CompactBlock LDX system, this module offers a space-saving footprint perfect for mounting directly on or near machinery. Its modular design allows you to daisy-chain multiple I/O blocks, reducing the amount of home-run wiring back to the main control cabinet and enabling faster, more cost-effective machine builds and retrofits.
FAQs
Q: Can the 1790D-T16BV0 handle both sinking and sourcing sensors?
A: Yes, this is a universal DC input block. It fully supports both sinking and sourcing 24V DC input configurations, giving you complete flexibility when integrating various field sensors and switches.
Q: What is the operating voltage range for the inputs to register an "On" state?
A: The module reliably detects an On-State when the input voltage is between 9.6V DC (minimum) and 28.8V DC (maximum), with a nominal rating of 24V DC.
Q: What I/O system is the 1790D-T16BV0 compatible with?
A: This input base block is designed exclusively for the Allen-Bradley CompactBlock LDX distributed I/O system, allowing for seamless expansion and integration with compatible network adapters.
Q: How much current does each input channel draw when active?
A: Each channel draws a maximum of 8 mA at 24V DC when in the On-State. Ensure your system power budget accounts for the total current draw of all active inputs.
