Allen-Bradley 1797-IBN16 FLEX Ex Input Module With 1797-TB3

Allen-Bradley 1797-IBN16 FLEX Ex Input Module with 1797-TB3

The Allen-Bradley 1797-IBN16 is a high-density, intrinsically safe input module made for dangerous places where normal electrical impulses could cause an explosion. This module is part of the FLEX Ex™ I/O family and has 16 sinking inputs. This lets you safely monitor digital field devices like push buttons or limit switches in Zone 1 or Zone 2.When you connect it to the 1797-TB3 Terminal Base, you have a strong, modular connection system that makes wiring easier and lets you “Remove and Insert Under Power” (RIUP), which keeps your process running even when you’re doing maintenance.

1797-IBN16 16-Point Digital Sinking Input Module Specifications

Key Features:

Why This Mix Works

-> Protection in Dangerous Areas: Designed to keep energy levels low so that sparks or heat don’t happen that could set off volatile atmospheres.

-> Space-Efficient Design: The FLEX Ex system has the same features as a big rack-based I/O but takes up less space, making it ideal for narrow spaces near the point of control.

-> Less complicated wiring: The 1797-TB3 terminal base has 24 terminals, which gives shields and grounds extra termination locations. This is very important for keeping signals clear in industrial settings.

-> Smart Diagnostics: The module has built-in LED indications that make it easier to find problems. They display which inputs are active at a glance and point out possible fault circumstances.
