Request a quote and current... Price & Availability It provides 16 individually isolated inputs that accept AC voltages from 85 to 265V AC, making it suitable for direct connection to 120V or 240V AC field devices such as limit switches, push buttons, and proximity sensors. The module features isolated inputs to prevent ground loops and enhance signal integrity in industrial environments. This module is part of Rockwell Automation's ControlLogix family, known for its modular and scalable architecture. The 1756-IA16I occupies a single slot in a 1756 chassis and communicates with the ControlLogix controller via the backplane. It supports a wide operating temperature range of 0 to 60°C and has a robust design for harsh industrial conditions. The module's isolation rating is 1800V continuous between input terminals and backplane, ensuring reliable operation. With a high input impedance of 12 kOhm at 50/60 Hz, the 1756-IA16I minimizes loading on field devices. It features an input off-state voltage of 40V AC or less and an on-state voltage of 79V AC or greater, providing clear switching thresholds. The module is ideal for applications requiring reliable AC sensing, such as motor control, packaging machinery, and material handling systems. The Allen-Bradley 1756-IA16I is a digital AC input module designed for the ControlLogix platform. Basic Product Information Wide input voltage range: 85-265V AC High input impedance: 12 kOhm at 50/60 Hz Isolation voltage: 1800V continuous between inputs and backplane Compatible with ControlLogix chassis and controllers LED indicators for each input for easy diagnostics 16 individually isolated AC inputs Technical Specifications Version & Model Difference The 1756-IA16I is the isolated version of the 1756-IA16 module. The non-isolated version (1756-IA16) does not provide individual input isolation, while the 'I' suffix indicates that each input is isolated from the others and from the backplane. This isolation helps prevent ground loops and improves noise immunity in industrial environments. There are no other major version differences; the module is part of the ControlLogix series and is compatible with all ControlLogix controllers. Application Scenarios Does the 1756-IA16I provide isolation between inputs? Yes, the 1756-IA16I has individually isolated inputs. Each input is isolated from the others and from the backplane, with an isolation rating of 1800V continuous. What is the backplane current requirement of the 1756-IA16I? The module draws 250 mA from the 5V backplane supply. It also dissipates 5.0 W of power, which should be considered when calculating the power budget of the chassis. Can the 1756-IA16I be used with any ControlLogix controller? Yes, the 1756-IA16I is compatible with all ControlLogix controllers, including L6x, L7x, and L8x series. It can be placed in any 1756 chassis and communicates via the backplane. What is the input voltage range of the 1756-IA16I? The 1756-IA16I accepts AC input voltages from 85 to 265V AC, making it suitable for both 120V and 240V AC applications.
