Introduction

Struggling to expand your automation system without adding complexity? The Allen-Bradley 1790-T8BV8VX CompactBlock LDX expansion module offers a straightforward solution. This module integrates 8 universal inputs and 8 sinking outputs into a compact design, simplifying system growth while maintaining reliable performance.

Technical Specifications Breakdown

The 1790-T8BV8VX operates on a nominal 24V DC supply with a voltage range of 11 to 28.8V DC, ensuring flexibility in various industrial environments. Its maximum power dissipation is just 1.2 watts at 28.8V DC, making it energy-efficient. Input specifications include an on-state voltage of 24V DC nominal and an off-state voltage of 5V DC maximum, with a nominal input impedance of 4.8 kΩ. Outputs feature an on-state voltage drop of 0.5V DC maximum and an off-state leakage current of 0.5 mA maximum. The module provides photocoupler isolation between I/O and logic, with an isolation voltage of 1250V AC RMS, enhancing system safety.

Industry Applications

This expansion module suits applications requiring flexible I/O configuration, such as packaging machinery, material handling, and assembly lines. For instance, in a packaging line, the 1790-T8BV8VX can handle sensor inputs and control actuator outputs, streamlining operations. Its 8 non-isolated inputs support both sinking and sourcing modes, adapting to different sensor types, while the 8 sinking outputs drive loads like relays or solenoids.

Installation & Setup Guidance

Mounting the 1790-T8BV8VX is straightforward using its screw mount design. Connect wiring via the terminal block (M3.0) with a screw torque of 7 lb-in maximum, using copper or copper-clad aluminum conductors. The built-in DeviceNet communication port simplifies networking with other automation components. Ensure the supply voltage stays within 11 to 28.8V DC for reliable operation.

Maintenance & Reliability

Regular inspection of the module's green status indicators helps monitor input and output health. The module's low power dissipation reduces heat stress, contributing to long-term reliability. Operate within an altitude limit of 2,000 meters above sea level to maintain performance. For complete technical specifications, contact BluePLC Industrial.
