Honeywell 900SP1-0100 Expansion Processor Module

Product Overview

The Honeywell 900SP1-0100 is an Expansion Processor Module (EPM) for the ControlEdge 900 and HC900 controller families. As an earlier-generation expansion processor, it provides the essential communication interface between remote I/O racks and the central Control Processor Module (CPM). The 900SP1-0100 enables cost-effective distributed control architectures while maintaining the reliability and determinism required for industrial process automation.

Key Features

• Expansion processor for distributed I/O rack communication
• Dual Ethernet connectivity for redundant network paths
• Auto-crossover RJ45 ports simplify installation wiring
• High electrical isolation protects against ground loops and noise
• Rotary switch addressing (1–99) for rack identification
• LED status indicators for quick diagnostics
• Compatible with ControlEdge PLC, UOC, and HC900 platforms

Selection Tips

• Choose the 900SP1-0100 for legacy system maintenance or when specifically required by existing controller firmware.
• For new installations, prefer the 900SP1-0200 or 900SP1-0300 for enhanced performance and wider temperature range.
• Always verify firmware compatibility with your CPM before ordering any EPM variant.
