Information About 1747-L30A
The 1747-L30A is a fixed I/O controller from the Allen-Bradley SLC 500 family, designed to provide a compact and reliable solution for small to mid-size industrial control systems. It features 30 total onboard I/O points, combining 18 AC input channels with 12 relay-based output channels for flexible field device interfacing. The controller operates on 120/240V AC power and supports DH-485 communication, allowing it to integrate into existing SLC and PanelView networks. With 1K words of user memory and compatibility with a two-slot expansion chassis, it offers modest program storage while allowing limited expansion for additional functionality. Its fixed architecture makes it suitable for standalone machines, small process loops, and equipment-level control tasks.
Key Features:
- Fixed 30-Point I/O Architecture: Provides 18 AC input channels and 12 relay output channels for direct device connection without additional modules.
- 1K Words User Memory: Offers essential program storage capacity for small-scale control tasks and machine logic sequences.
- DH-485 Communication Support: Enables integration into SLC networks, PanelView HMIs, and other DH-485-compatible devices.
- 120/240V AC Power Operation: Supports common industrial power supplies for simplified installation and compatibility.
- Relay Contact Digital Outputs: Allows direct switching of AC or DC loads without additional output modules.
- 120V AC Digital Inputs: Designed for direct monitoring of industrial pushbuttons, switches, and sensor signals.
- Two-Slot Expansion Compatibility: Provides limited expansion capability through an optional expansion chassis to add specialty modules.
- Built-In Processor Module: Combines CPU, power supply, and I/O in one hardware package for compact and efficient use.
- Suitable For Standalone Machines: Ideal for packaging, material handling, and small automated systems requiring modest control capacity.
- 50/60 Hz Operation: Ensures flexibility across regions and compatibility with global industrial AC standards.
The 1747-L30A delivers the reliability and precision required for compact SLC 500 automation tasks where fixed I/O and DH-485 networking are essential.
