Overview
The Allen-Bradley 5820-EI/A Ethernet Pyramid Integrator Interface Module is a legacy integration solution for industrial automation systems requiring network-based communication with Pyramid Integrator PLCs. This discontinued module provides an economical gateway for connecting existing host computers to automation equipment without costly system redesign. Engineers and maintenance teams rely on the 5820-EI/A to extend the operational life of established control systems while leveraging standard Ethernet infrastructure.
Key Features
- Reduced Integration Costs – Eliminates the need for expensive system overhauls by using existing host computers and network infrastructure
- Standard Network Management – Implements standard Simple Network Management Protocol (SNMP) for monitoring and control
- Legacy PLC Compatibility – Purpose-built for Pyramid Integrator series equipment, ensuring reliable communication in older automation environments
- Straightforward Installation – Drops into existing Pyramid Integrator racks without requiring system modifications

Typical Applications
The 5820-EI/A serves critical roles in:
- Legacy manufacturing floor automation requiring Ethernet connectivity to older PLC platforms
- System integration projects that must preserve existing Pyramid Integrator investments
- Industrial environments needing cost-effective network gateway solutions without complete system replacement
- Facilities transitioning older control systems while maintaining operational continuity
Compatibility & Replacements
As a discontinued Allen-Bradley component, the 5820-EI/A is increasingly difficult to source from factory channels. This used unit represents a practical, cost-saving option for replacement, repair, and maintenance work. When considering alternatives, engineers should verify compatibility with their specific Pyramid Integrator configuration and consult Rockwell Automation technical documentation. Original manufacturer warranty does not apply to used surplus units; however, thorough testing and inspection confirm operational readiness.
