The Allen-Bradley 1756-IF16 ControlLogix® Analog Input Module provides high-precision signal acquisition for industrial process control. Designed for Rockwell's ControlLogix platform, this 16-channel module supports configurable voltage (±10V, 0-10V) and current (0-20mA, 4-20mA) inputs with 24-bit delta-sigma ADC resolution.
Featuring Channel-to-Channel Isolation (250V AC) and 1500V AC backplane isolation, it eliminates ground loops while withstanding EMI/RFI interference (EN 61000-6-2). Its robust aluminum housing operates at -40°C to +70°C with NEMA 4X/IP67 protection (using 1756-TBNH terminals). Embedded diagnostics include open-wire detection, over-range alerts, and timestamped data for predictive maintenance integration in Studio 5000® environments.
