Overview
The Modicon AS-212P-220 is an ASCII interface board engineered for the P453 controller platform. This legacy module provides essential communication and interface capabilities for classic Modicon PLC architectures. Organizations maintaining or upgrading mature automation systems frequently specify the AS-212P-220 to restore critical functionality and ensure system continuity.
Key Features
- ASCII protocol communication interface for P453-based systems
- Designed for legacy Modicon PLC integration and expansion
- Plug-and-play compatibility with P453 processor architecture
- Supports data exchange and terminal communication in industrial environments
- Proven reliability in mature automation installations
Technical Specifications
The AS-212P-220 is manufactured by Modicon (Schneider Electric) as a dedicated interface module. It integrates directly into P453-based control racks and mainframes. The module handles ASCII protocol communications, allowing terminal devices and external systems to exchange data with the P453 processor. Its compact form factor aligns with standard Modicon I/O rack mounting requirements.
Typical Applications
- Legacy Modicon P453 system upgrades and maintenance
- ASCII terminal interface integration for operators and diagnostics
- Data communication between P453 controllers and external devices
- Retrofit installations where protocol translation is required
- Industrial environments requiring proven, proven-design hardware
