Honeywell 900SP1-0300 Expansion Processor Module

Product Overview

The Honeywell 900SP1-0300 is an Expansion Processor Module (EPM) for the ControlEdge 900 series. Acting as the communication bridge between expansion I/O racks and the Control Processor Module (CPM), the 900SP1-0300 enables scalable, distributed control architectures. With a dual-core ARM® Cortex™-A9 processor, dual Ethernet ports, and robust isolation, this module is engineered for high-availability process automation in extreme industrial environments.

Key Features

• Dual-Core ARM® Cortex™-A9 processor at 667 MHz for high-speed data handling
• 2 × RJ45 Ethernet ports with auto-crossover and 10/100BaseTx auto-detection
• 1500 V RMS isolation for 1 minute — protects against electrical noise and ground loops
• 600 W peak pulse power transient protection (10×1000 μs waveform)
• Extended temperature range: −40°C to +70°C
• Rotary switch addressing (1–99) for simple rack identification
• Dual three-color LED diagnostics per port for instant status visibility

FAQ

Installation Guide

1. Power Off: Ensure the HC900 rack is completely de-energized before installing the 900SP1-0300.
2. Slot Placement: Insert the module into the designated expansion processor slot in the I/O rack. Press firmly until fully seated.
3. Address Setting: Use the rotary switch to set the unique rack address (1–99) before powering on.
4. Ethernet Cabling: Connect shielded CAT5e/CAT6 cables to the RJ45 ports. Use auto-crossover capability to simplify switch connections.
5. Network Verification: Power on and verify link LEDs illuminate. Check communication status in the Hybrid Control Designer software.
6. Expansion Rack Daisy-Chain: If connecting multiple expansion racks, plan network topology to ensure adequate bandwidth and switch port capacity.

Selection Tips

• Select the 900SP1-0300 for ControlEdge 900 / HC900 systems requiring remote I/O rack expansion.
• For legacy HC900 systems, verify compatibility with your controller firmware revision.
• Ensure Ethernet switch ports support the required 10/100BaseTx speed and have sufficient capacity for all expansion racks.
• Use shielded industrial Ethernet cables to maintain signal integrity in electrically noisy environments.
• Plan rack addressing in advance to avoid conflicts in multi-rack configurations.
