Honeywell 900SP1-0200 Expansion Processor Module

Product Overview

The Honeywell 900SP1-0200 is an Expansion Processor Module (EPM) designed for the ControlEdge PLC and Unit Operations Controller (UOC) platforms. It serves as the communication and processing interface between remote expansion racks and the central controller, enabling deterministic data transfer across industrial Ethernet networks. With a dual-core ARM® Cortex™-A9 processor, dual auto-crossover Ethernet ports, and 1500 V RMS isolation, the 900SP1-0200 delivers reliable distributed I/O connectivity for scalable automation.

Key Features

• Dual-core ARM® Cortex™-A9 processor at 667 MHz
• 2 × RJ45 Ethernet ports with auto-crossover and 10/100BaseTx auto-detection
• 1500 V RMS isolation for protection against electrical interference and ground loops
• 600 W peak pulse transient protection (10×1000 μs waveform)
• Rotary switch addressing (1–99) for quick rack identification
• LED diagnostics per port for network status and fault identification
• Compact modular design for ControlEdge rack integration

FAQ

Installation Guide

1. Power Off: De-energize the ControlEdge rack before module installation.
2. Slot Insertion: Align the 900SP1-0200 with the expansion processor slot and press firmly until the retention clips engage.
3. Address Configuration: Set the rotary switch to the desired rack address (1–99) using a small flat-blade screwdriver.
4. Ethernet Connection: Connect shielded industrial Ethernet cables to both RJ45 ports. The auto-crossover feature eliminates the need for crossover cables.
5. Grounding: Ensure the rack chassis is properly grounded to the cabinet earth bus.
6. Commissioning: Power on and verify port LEDs indicate link status. Confirm rack communication in the control system configuration software.

Selection Tips

• Use the 900SP1-0200 for ControlEdge PLC/UOC systems requiring deterministic remote I/O expansion.
• For newer HC900 safety systems, consider the 900SP1-0300 with extended −40°C to +70°C temperature range.
• Verify controller firmware revision supports the EPM before ordering.
• Plan network topology to accommodate all expansion racks with adequate switch port capacity.
• Use industrial-grade shielded Ethernet cables to ensure reliable communication in noisy environments.
