Product Overview
When process uptime is critical, the Schneider BMEH584040 redundant processor module delivers high availability for your Modicon M580 system. This module supports up to 61 Ethernet devices and 16 remote I/O racks of X80 and Quantum I/O, making it ideal for demanding industrial applications.
Technical Specifications Breakdown
The BMEH584040 offers robust performance with 16 MB of integrated program memory and 2048 kB of data memory. It consumes 360 mA at 24 V DC and provides 30 Kinstructions/ms (65% Boolean + 35% fixed arithmetic) or 40 Kinstructions/ms (100% Boolean). The module operates in ambient temperatures from 32 to 140 °F (0 to 60 °C) and has an MTBF of 650,000 hours. Its IP20 degree of protection suits clean indoor environments.
Industry Applications
In process control applications, the BMEH584040 excels at managing HART devices, SSI encoders, motion control, and accurate time stamping. For example, a chemical plant using redundant processors can maintain production during a primary processor failure, minimizing downtime. The module supports 16 remote I/O stations with up to 2 X80 and Quantum drops, enabling distributed control across large facilities.
Installation & Setup Guidance
Mount the BMEH584040 on a single rack and connect the internal power supply via the rack. Use the integrated Ethernet TCP/IP service port, two device network ports, and the dedicated HSBY port for hot standby communication. The USB mini B port allows local programming. Ensure the ambient temperature stays within 0 to 60 °C and avoid condensation.
Maintenance & Reliability
With an MTBF of 650,000 hours, the BMEH584040 requires minimal intervention. Regularly inspect the status LEDs for processor running (RUN), system fault (ERR), and I/O module fault (I/O). The module withstands vibration up to 3 gn and shock up to 30 gn. For storage, keep temperatures between -40 and 185 °F (-40 to 85 °C).
Compatibility & Integration
The BMEH584040 integrates seamlessly with Modicon M580 architecture. It supports 8 AS-Interface modules and 16 Ethernet communication modules. Communication services include RIO scanner and DIO scanner. The module is Achilles certified and includes cybersecurity features like IPSec, SNMP logging, and an embedded firewall.
Selection Guide & Purchasing Advice
Before purchasing, verify your system requires a redundant processor module. The BMEH584040 is TAA compliant and comes from France. SpareTechPLC stocks this module ready to ship. Confirm compatibility with your existing M580 rack and power supply. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
