Allen-Bradley 1756-IB16 Digital Input Module

The Allen-Bradley 1756-IB16 is a 16-channel digital input module for the ControlLogix 5570 and 5580 Programmable Automation Controllers (PACs). It interfaces with external devices by reading digital signals (on/off states) and transmitting them to the PAC for processing.

Overview:
Function: Reads digital ON/OFF signals from sensors, switches, and other digital devices.
Number of Channels: 16 independent channels, each configurable for sinking or sourcing operation.
Input Voltage Range:
Sinking Operation: -31 VDC to +26.4 VDC
Sourcing Operation: 17 VDC to 31.5 VDC
Input Current: Up to 2 mA per channel
Isolation: 2500 Vrms between channels and to ground for noise immunity and protection.
Status Indicators: LEDs for individual channels and module health.

Features:
High-density design: Provides 16 channels in a compact module, saving space in the control cabinet.
Configurable operation: Each channel can be independently set for sinking or sourcing operation for flexibility.
Fast scan rate: Up to 2.5k samples per second per channel for real-time processing of rapid signal changes.
Diagnostics: Built-in diagnostics help identify and troubleshoot potential issues.
Wide operating temperature: Operates reliably in environments with temperatures from -40°C to +70°C (-40°F to +158°F).

Applications:
Industrial automation: Monitoring machine status, limit switches, safety interlocks, and other digital signals in various industrial applications.
Process control: Reading sensor data from process equipment, including flow meters, pressure sensors, and level sensors.
Building automation: Monitoring building systems such as HVAC, lighting, and security in commercial and residential buildings.
Material handling: Detecting the presence and position of objects on conveyor belts, sorting systems, and other material handling equipment.
