Product Summary
The 1746-IA4 from Rockwell Automation is a robust SLC 500 Digital AC Input Module. This unit provides four reliable input channels for your control system. It operates efficiently within a voltage range of 85 to 132 Volts AC. Engineers trust this module for general-purpose industrial applications.
Theme Option A: Product Procurement & Buyer Guide
Understanding the 1746-IA4 Specifications
Procurement teams must verify the exact voltage requirements. The 1746-IA4 accepts a nominal input of 120V AC. Its operational frequency spans from 47 to 63 Hz. This module draws only 35 milliamps from the 5V DC backplane. This low power consumption reduces overall system heat.
Critical Electrical Parameters for Selection
The module has a maximum off-state voltage of 30V AC. Its nominal input current is 12 mA at 129V AC. The off-state current is a maximum of 2 milliamps. These values ensure clear signal distinction for your logic. The signal on delay is 35 milliseconds maximum. The signal off delay is 45 milliseconds maximum.
Thermal and Physical Considerations
This component dissipates a minimal 0.175 watts of power. Its maximum thermal dissipation reaches 1.3 watts. The operating temperature range is 32 to 140 degrees Fahrenheit. The module dimensions are 5 x 2 x 6 inches. It weighs only 0.17 kilograms for easy handling.
Installation and Connection Details
The module occupies a single slot in the SLC 500 chassis. It uses I/O connections like the 1746-HT or 1746-HCA. The step response time is 100 milliseconds for input. The output step response is a fast 2.5 milliseconds. This performance suits high-speed discrete monitoring tasks.
Application Fit for Engineers
Engineers choose this module for general-purpose digital sensing. It reliably reads signals from push buttons and limit switches. The 4-channel density optimizes space in your rack. This module provides a status display for quick diagnostics. Its open-style enclosure allows for easy integration.
