Product Overview
The 1790-T16BV0X is a 24V dc 16 Universal Input Base and Expansion Module from Allen-Bradley, designed for flexible industrial automation. This module supports 16 input points configurable as sinking or sourcing, with 8 points/8COM non-polarity common type. It integrates seamlessly into DeviceNet networks for reliable data acquisition.
Technical Specifications Analysis
The 1790-T16BV0X operates with an on-state voltage range of 9.6V dc min to 28.8V dc max, with a nominal 24V dc. Off-state voltage is 5.0V dc max. On-state current reaches 8 mA max per channel at 28.8V dc. Input impedance is 4.8 KΩ nominal. The module dissipates 1.2 W max power at 28.8V dc. Isolation between I/O and logic uses photocoupler isolation rated at 1250V ac rms. DeviceNet power to logic is nonisolated. Indicators include 16 green input status LEDs. Wiring uses a terminal block (M3.0) with screw torque of 7 lb-in max, requiring copper or copper-clad aluminum conductors.
Application Scenarios & Usage Methods
In oil and gas facilities, the 1790-T16BV0X monitors discrete sensors like limit switches and proximity detectors. Use it in pump control panels to detect valve positions or flow status. In manufacturing lines, it reads inputs from push buttons or photoelectric sensors. Configure inputs as sinking or sourcing to match sensor types. The 8 points/8COM grouping simplifies wiring for grouped sensors. Connect the module to a DeviceNet scanner for centralized control.
Installation Guide & Packing List
Mount the base module on a DIN rail or panel. Ensure 24V dc supply voltage within 11…28.8V dc range. Wire inputs using copper conductors, tightening terminal screws to 7 lb-in max. Ground the module per local codes. The package includes the 1790-T16BV0X base module and terminal block. Expansion modules sold separately.
Purchasing Advice
Choose the 1790-T16BV0X for applications needing 16 universal inputs with DeviceNet connectivity. Verify your system voltage matches the 24V dc nominal. For grouped input wiring, the 8 points/8COM common type reduces cabling. PetroPartsOnline stocks genuine Allen-Bradley modules with fast shipping.
Repair & Maintenance Tips
Periodically check input status LEDs for proper operation. Clean the module with a dry cloth; avoid solvents. Store in a dry, static-free environment. Inspect wiring for loose connections and tighten screws to 7 lb-in max. Replace the module if input readings become erratic.
