Honeywell 900SP1-0100 Expansion Processor Module for ControlEdge 900

Product Overview

The Honeywell 900SP1-0100 Expansion Processor Module (EPM) serves as the critical interface between expansion I/O racks and the control processor module (CPM) in the ControlEdge 900 platform. This module is essential for I/O racks that need to communicate with CPMs located in a different rack, ensuring reliable data exchange across distributed systems.

Technical Specifications

At the heart of the 900SP1-0100 lies a dual-core ARM Cortex-A9 processor running at 667 MHz, providing robust processing power for handling expansion I/O communication. The module features a rotary address switch that allows you to set the rack address from 1 to 99, offering flexible configuration for multi-rack setups. Two tri-color LEDs indicate the operational status of the EPM at a glance.

For network connectivity, the module includes two Ethernet ports with shielded RJ45 connectors that support auto-crossover. Each port operates at 10/100BaseTx with auto-detecting speed. The ports provide 1500 Volts RMS isolation at 60 Hz for one minute and include transient voltage suppression rated at 600W peak pulse power. Diagnostic LEDs on each port help with quick troubleshooting.

Network Topology and Communication

The ControlEdge 900 platform supports both star and ring topologies for the expansion I/O network, using standard RJ45 connections for redundant and non-redundant systems. Maximum cable length for shielded Ethernet cable is 100 meters (328 feet) from CPM to EPM or to a switch. For fiber optic connections, the maximum distance extends to 5000 meters (16404 feet). The module uses I/O Communication protocol on both ports.

Power and Heat Dissipation

The 900SP1-0100 consumes only 2.6W of power, with an equal heat dissipation of 2.6W. This low power consumption makes it suitable for installations where thermal management is a concern, reducing overall energy costs and simplifying cooling requirements.

Installation and Setup

When installing the EPM, set the rotary address switch to the desired rack address between 1 and 99. Use shielded CAT5 copper cables for standard connections or multi-mode duplex fiber optic cables with SC connectors for longer distances. For fiber optic setups, qualified Moxa switches such as the EDS-308 or EDS-308-MM-SC are recommended. Always verify that the network topology (star or ring) matches your system architecture before commissioning.

Compatibility and Integration

The 900SP1-0100 is designed exclusively for the Honeywell ControlEdge 900 platform. It works seamlessly with compatible CPMs and expansion I/O racks. The module supports both redundant and non-redundant system configurations, making it a versatile choice for various industrial automation architectures.

Selection and Purchasing Advice

Before ordering the 900SP1-0100, confirm that your system uses the ControlEdge 900 platform and that the expansion I/O rack requires a separate EPM for communication. Ensure you have the appropriate shielded Ethernet cables or fiber optic components as specified.
