Allen-Bradley | 1762-IQ16 | MicroLogix 1200 (1762 Series)

Product Description: Allen-Bradley 1762-IQ16

The Allen-Bradley 1762-IQ16 is a 16-channel digital input module designed for use with MicroLogix 1100, 1200, and 1400 controllers. It supports both sinking (NPN) and sourcing (PNP) 24V DC input devices, offering flexibility in wiring and application design. This high- density input module is ideal for monitoring proximity switches, pushbuttons, limit switches, and other field sensors in compact industrial control systems.
