Product Summary
The Allen-Bradley 1746-IA16 is a robust SLC 500 Digital AC Input Module. It provides sixteen input channels for real-time discrete device monitoring. This module accepts an AC voltage range of 85-132 Volts. It occupies a single slot in the SLC 500 chassis. This component is essential for accurate PLC program execution.
Product Procurement & Buyer Guide
Why Choose the 1746-IA16 for Your System?
The 1746-IA16 delivers a reliable interface for standard AC signaling devices. Procurement managers appreciate its single-slot design for space efficiency. This module uses a removable terminal block for easy wiring. You can replace the module without disconnecting field wiring. This feature significantly reduces downtime during maintenance.
Critical Technical Specifications for Engineers
This module has a voltage range of 85-132 Volts AC. It consumes only 85 milliamps from the 5V DC backplane. The module offers an ON-delay of 35 milliseconds maximum. Its OFF-delay signal reaches 45 milliseconds maximum. The OFF-state voltage is a maximum of 50V AC. These specs ensure precise signal detection for your logic.
Installation Flexibility and Compatibility
You can install this module in any SLC 500 chassis with an open slot. It works in fixed or modular hardware configurations. You can place it locally or in an expansion rack. The 1746-IA16 is a general-purpose input application module. It has 16 points per common for simplified wiring.
Understanding the Voltage Category
This module belongs to the 100-120V AC operating voltage category. For 200/240V AC operations, use the 1746-OM16 counterpart. Note that neither module offers internal protection circuitry. Your AC input device must be compatible with the inrush current. The module has a maximum inrush current of 0.8 mA.
Backplane Current and Power Consumption Details
The module draws 85 milliamps from the 5V DC backplane. It draws zero amps from the 24V DC backplane. The power consumption is 0.27 watts per point minimum. The total power consumption for the module is 4.8 Watts. This low power draw makes it efficient for large systems.
Physical Dimensions and Weight
The Allen-Bradley 1746-IA16 weighs only 0.34 kg. Its dimensions are 5 x 2 x 6 inches. This compact size allows for easy handling and installation. The module uses a chassis-type mounting method. Its robust design ensures long-term reliability in harsh environments.
