Allen-Bradley 1790D-T16BV0 Universal DC Input Base Block for CompactBlock LDX

Product Introduction

As industrial automation evolves, control systems demand flexible, reliable I/O modules that simplify wiring and withstand harsh environments. The Allen-Bradley 1790D-T16BV0 universal DC input base block from the CompactBlock LDX series meets these needs with a versatile design for 24V DC applications. It handles 16 input channels supporting both sink and source configurations, reducing inventory complexity and installation time.

Technical Specifications Breakdown

The 1790D-T16BV0 operates with a nominal supply voltage of 24V DC and a voltage range of 11 to 28.8V DC. It provides photocoupler isolation between I/O and logic with an isolation voltage of 1250V AC rms, ensuring signal integrity and protection. The module uses a terminal block with M3.0 screws, and the maximum screw torque is 7 lb-in when using copper or copper-clad aluminum conductors. DeviceNet connections to logic and power are nonisolated.

Industry Applications

In manufacturing lines, the 1790D-T16BV0 connects sensors and switches for material handling, packaging, and assembly. Its 16-point input capacity suits medium-density control panels. The module's 30 g peak shock and 5 g vibration tolerance at 10 to 500 Hz make it suitable for conveyor systems and robotic cells. Operating from 0 to 60 degrees Celsius and 5 to 90% non-condensing humidity, it performs reliably in factory floors and warehouses.

Installation & Setup Guidance

Mount the 1790D-T16BV0 on a DIN rail within the CompactBlock LDX system. Connect 24V DC power within the 11 to 28.8V DC range. Wire inputs using the terminal block; tighten M3.0 screws to 7 lb-in maximum. Use copper or copper-clad aluminum conductors. Verify that the DeviceNet network connections are properly terminated and that the base module receives adequate power.

Maintenance & Reliability

Periodically inspect the terminal block connections for tightness and check for signs of corrosion or moisture. The module's non-condensing humidity tolerance (5 to 90%) reduces risk in damp environments. The photocoupler isolation protects against voltage transients, extending service life. Regular system diagnostics help identify input faults early, minimizing downtime.

Selection Guide & Purchasing Advice

When selecting the 1790D-T16BV0, confirm your system voltage is 24V DC and that your DeviceNet network supports the base module's power requirements. Verify compatibility with your CompactBlock LDX backplane and any existing I/O modules. For current availability and lifecycle status, contact BluePLC Industrial.
