Product Introduction
When expanding your Honeywell 900SP1-0100 control system, the Expansion Processor Module (EPM) ensures seamless communication between I/O racks and control processor modules in different racks. This module acts as the critical interface between expansion I/O and the control processor, enabling reliable data exchange and system scalability.
Technical Specifications Breakdown
The Honeywell 900SP1-0100 EPM features a Dual Core ARM Cortex-A9 processor (32-bit, 667 MHz) for high-speed processing. It includes a rotary address switch to set the rack address range from 1 to 99, and two tri-color LEDs for status indication. Key communication specifications include:
- 2 Ethernet ports with shielded RJ45 connectors (auto-crossover)
- Network speed: 10/100BaseTx, auto-detecting
- Isolation: 1500 Volts RMS for 1 minute at 60 Hz
- Transient voltage suppression: 600W peak pulse power capability
- Diagnostic LEDs on each port
- Protocols: I/O Communication
The module supports Star or Ring topology for the expansion I/O network using standard RJ45 connections, with maximum cable lengths of 100 m (328 ft.) for shielded Ethernet cable and 5000 m (16404 ft.) for fiber optic cable. Power consumption and heat dissipation are both 2.6W.
Industry Applications
In process control environments such as oil refineries and chemical plants, the Honeywell 900SP1-0100 allows operators to expand their system with additional I/O racks without performance degradation. For manufacturing facilities, it facilitates integration of remote I/O stations, reducing cabling costs and improving flexibility. As an upgrade for legacy interface modules, the 900SP1-0100 provides faster data throughput and advanced diagnostics.
Compatibility & Integration
The Honeywell 900SP1-0100 is part of the ControlEdge 900 platform and works seamlessly with compatible CPMs and I/O racks. It supports redundant and non-redundant system configurations with Star or Ring topologies. For fiber optic connections, recommended equipment includes Moxa unmanaged Ethernet switches such as the EDS-308, EDS-308-MM-SC, or EDS-316-MM-SC, and the Moxa IMC-101-M-SC converter. Copper connections require shielded CAT5 cable, while fiber optic cable should be multi-mode, duplex, 62.5/125 with SC connectors.
Selection Guide & Purchasing Advice
Before purchasing the Honeywell 900SP1-0100 Expansion Processor Module, verify that your system uses the ControlEdge 900 platform and that you have the necessary rack slots. Ensure compatible power supplies (24VDC for switches) and network cables.
