Allen‑Bradley 1762‑IQ16 MicroLogix Digital Input Module 16 Point 24V DC

Sink/source digital input module for MicroLogix 1100, 1200, and 1400 systems, providing 16 discrete input channels for interfacing sensors, pushbuttons, and limit switches.

The Allen‑Bradley 1762‑IQ16 is a 16‑point digital input module in the MicroLogix 1762 expansion I/O family. It features 24V DC sink/source inputs with optical isolation, allowing connection to a wide range of field devices while protecting the backplane from electrical noise. The module is compatible with MicroLogix 1100, 1200, and 1400 controllers, and supports both sinking and sourcing wiring configurations. Used in MicroLogix 1400 automation systems with PLC, I/O, HMI, and industrial network components.

Applications:

• Discrete signal acquisition from sensors and switches

• Factory automation and assembly line monitoring

• Conveyor and material handling systems

• Machine control and OEM equipment

• Remote I/O expansion for MicroLogix PLCs

Key Features:

• 16 digital inputs (sink/source, configurable per group)

• 24V DC nominal (20.4‑26.4V DC operational range)

• Optical isolation between input field power and backplane

• Removable terminal block for easy wiring

• Hot‑swappable under power (RIUP) – requires power module shutdown coordination

• Built‑in input filtering for noise rejection (programmable)

• DIN rail or panel mount
