Allen-Bradley 1790-16BV0X 16-Point Universal Input Module Overview

Product Introduction

The Allen-Bradley 1790-16BV0X is a 24V dc 16 universal input base and expansion module designed for industrial automation systems. Part of the 1790 series, this module provides 16 input points that can be configured as either sinking or sourcing, offering flexibility for various sensor and switch connections. With a compact design and robust specifications, the 1790-16BV0X is ideal for monitoring discrete signals in manufacturing, process control, and material handling applications.

Technical Specifications Breakdown

The 1790-16BV0X operates within a voltage range of 11 to 28.8V dc, with a nominal supply voltage of 24V dc. This wide range ensures stable performance even in fluctuating power conditions. The module features photocoupler isolation between I/O and logic, providing 1250V ac rms isolation voltage for enhanced protection against electrical noise and surges. Note that DeviceNet to logic and DeviceNet power are nonisolated, so proper grounding practices are essential.

Each of the 16 inputs can handle an on-state voltage from 9.6V dc minimum to 28.8V dc maximum, with a nominal of 24V dc. The off-state voltage is 5.0V dc maximum, and the on-state current reaches 8 mA per channel at 28.8V dc. Input impedance is nominally 4.8 KΩ. The module uses an 8 points per common configuration with 8COM, and polarity is nonpolarity, simplifying wiring.

Power dissipation is 1.2 W maximum at 28.8V dc, and the module includes 16 green input status indicators for easy diagnostics. Wiring is via a 37-pin D-shell connector, ensuring reliable connections.

Industry Applications

The 1790-16BV0X is well-suited for discrete input monitoring in automated assembly lines, packaging machinery, and conveyor systems. Its sinking/sourcing capability allows direct connection to both NPN and PNP sensors, reducing the need for additional interface modules. In material handling, the module can monitor limit switches, proximity sensors, and photoelectric sensors, providing real-time status to the control system. The photocoupler isolation ensures signal integrity in electrically noisy environments, such as near motors or variable frequency drives.

Compatibility & Integration

This module integrates with Allen-Bradley controllers and DeviceNet networks. The DeviceNet power is nonisolated, so ensure the network power supply is properly grounded. The 37-pin D-shell connector facilitates straightforward wiring to field devices. For systems requiring expansion, the 1790-16BV0X can be used as a base or expansion block, scaling I/O counts as needed.

Selection Guide & Purchasing Advice

When selecting the 1790-16BV0X, verify that your system voltage is within the 11 to 28.8V dc range and that your controller supports DeviceNet communication. Confirm the wiring connector type (37-pin D-shell) matches your cabling. For reliable supply and expert support, contact BluePLC Industrial, your trusted source for industrial automation parts.
