Allen-Bradley 1790-T0V16X 24V DC 16-Point Sinking Output Module

Product Overview

When your automation system demands reliable discrete output control, the Allen-Bradley 1790-T0V16X delivers consistent performance. This 24V DC 16-point sinking output module is designed for maintenance engineers who value ease of service and long-term dependability. Part of the 1790 series, it provides a straightforward solution for controlling actuators, indicators, and other low-power loads in industrial environments.

Technical Specifications Breakdown

The 1790-T0V16X features 16 nonisolated sinking outputs with a nominal on-state voltage of 24V DC. Each output can handle up to 0.5 A continuous current, with a total of 4.0 A maximum per common. The module offers fast switching with an off-to-on delay of 0.5 ms maximum and an on-to-off delay of 1.0 ms maximum. Photocoupler isolation between I/O and logic ensures reliable signal integrity, with an isolation voltage rating of 1250V AC RMS. The module includes 16 green status indicators for quick visual diagnostics, simplifying troubleshooting during routine maintenance.

Industry Applications

In manufacturing lines, the 1790-T0V16X controls solenoid valves, pilot lights, and small relays. Its fast switching response supports high-speed sorting and packaging machines where precise timing is critical. Maintenance engineers appreciate the module's straightforward design, which reduces downtime during replacement or system upgrades. The sinking output configuration integrates seamlessly with many PLC and controller systems, making it a versatile choice for both new installations and legacy system retrofits.

Installation & Setup Guidance

Mount the 1790-T0V16X on a DIN rail or panel using the provided terminal block with M3.0 screws. Tighten screws to a maximum torque of 7 lb-in, using copper or copper-clad aluminum conductors. Ensure the field power supply voltage stays within 10…28.8V DC and the base module supply within 11…28.8V DC. The module's compact footprint simplifies wiring in crowded cabinets. Always verify polarity and load ratings before powering up to prevent damage.

Maintenance & Reliability

For maintenance engineers, the 1790-T0V16X offers easy visual status checks via its 16 green indicators. Regularly inspect the terminal block connections for tightness and signs of corrosion. The photocoupler isolation helps protect against voltage transients, extending module life in electrically noisy environments. With a maximum power dissipation of 1.2 W at 28.8V DC, the module runs cool, reducing thermal stress on surrounding components. These features contribute to lower total cost of ownership by minimizing unplanned downtime.

Compatibility & Integration

The 1790-T0V16X integrates with Allen-Bradley controllers and other systems that support 24V DC sinking output modules. Its DeviceNet base module power supply simplifies network connectivity. The module's nonisolated outputs share a common connection, with 8 points per common and 2 commons total. This arrangement allows flexible grouping of loads while maintaining straightforward wiring. Always consult the system manual for specific controller compatibility and configuration settings.

Buying Guide & Selection Advice

Before purchasing the 1790-T0V16X, confirm your system's voltage requirements and load current needs. Verify that the output current per channel does not exceed 0.5 A and the total per common stays under 4.0 A. For applications requiring higher current or isolated outputs, consider alternative modules. BluePLC Industrial offers the 1790-T0V16X with fast shipping and expert support.
