Compact & Powerful: 16-Point Input Module with Built-in Network

Core Overview

The Allen-Bradley 1791D-16V0 is a compact input module. It has 16 built-in sourcing input points. The module includes a DeviceNet adapter. It also has an integrated power supply. This 1791D-16V0 module can operate alone. It can also work with expansion modules. With an input expansion module, it produces 5 input bytes. With an output expansion module, it produces 3 input bytes and uses 2 output bytes. It is designed for tight spaces.

Frequently Asked Questions

Can this module directly control a motor?

No. The 1791D-16V0 module is input-only. It only receives signals. You need an output expansion module or another device to control a motor.

What if the status indicator is off?

First, check if the power is between 11-25V DC. Then confirm the DeviceNet connection is correct. The LED will also be off if the logic is disabled.

Can I connect two expansion blocks?

No. Each 1791D-16V0 base module supports only one expansion block. You can connect either one input or one output expansion module.

Any wiring precautions?

Be aware of static electricity. Touch grounded metal before handling. Ensure power is off before wiring. Use proper tools and do not over-tighten terminals.

Is communication with the PLC slow?

No, delay is minimal. It uses DeviceNet for fast communication. The built-in DeviceLogix technology also allows quick local control.
