Emerson A6560R (Part No. D25625) serves as the core CPU processing board for the Emerson AMS6500 (CSi6500) online predictive machinery health monitoring system, engineered exclusively for online predictive vibration monitoring of rotating equipment. A transient data acquisition variant designated A6560RT was developed on the identical hardware platform.
Integrated with an FPGA and real-time signal processor, this board pairs with the A6510 analog input daughterboard. A single board accommodates 12 or 24 analog vibration channels alongside 2 to 4 tachometer speed pickup channels, enabling on-site high-speed spectral computation, bearing fault diagnostics, order tracking and PeakVue envelope analysis locally. Onboard alarm logic can be executed independently without reliance on a host PC.
Featuring multi-protocol connectivity via Modbus TCP, dual-port Ethernet and RS232 interfaces, it facilitates data interconnection with distributed control systems (DCS) and the AMS Machinery Manager host software. As the primary controller for online condition monitoring systems deployed on critical rotating machinery across petrochemical, power generation and metallurgical industries, D25625 is the original OEM ordering part number compatible with all standard AMS6500 rack assemblies.

Core Advantages
On-site Edge Computing to Reduce Host WorkloadEquipped with onboard FPGA real-time processor, the board performs all spectrum, PeakVue and order analysis locally. Only processed result data is uploaded, drastically cutting LAN data traffic across plant networks. Monitoring data is cached in onboard memory during network outages and automatically backfilled once communication resumes, enabling unattended offline monitoring.
Proprietary OEM PeakVue Patented TechnologyEmerson’s exclusive bearing fault detection algorithm accurately identifies incipient micro-damage on rolling-element bearings and gears, delivering fault alerts for fatigue spalling and pitting months in advance. Differentiated from conventional spectrum analysis, it serves as a core technology for predictive maintenance of heavy-duty rotating machinery.
Robust Reliability for Wide Operating ConditionsFull-board conformal coating compliant with IPC-A-610E supports operating temperatures ranging from -20℃ to 60℃. The unit has passed stringent IEC60068 vibration and shock qualification tests and delivers stable performance in refinery and power plant environments featuring extreme temperature swings, dust, high humidity and intense vibration. It meets EU RoHS and REACH environmental directives.
Multi-format Data CompatibilitySupports unit output in Imperial, Metric and SI standards including Hz, CPM and orders; three optional axis scales: linear, logarithmic and dB; selectable Hanning and rectangular window functions. Featuring Modbus TCP connectivity for mainstream DCS platforms, it integrates seamlessly with Emerson DeltaV and Ovation automation control systems.
Flexible Channel ScalabilityOne A6510 acquisition daughterboard (12 channels) or two A6510 boards (24 channels) can be fitted per main board to adjust measurement points on demand. Modular plug-in rack mounting facilitates convenient on-site retrofit and capacity expansion.

FAQ
Q: How to select between A6560R D25625 and A6560RT?A: Choose D25625 (A6560R) for long-term steady-state online monitoring of conventional pumps and fans. For steam turbines, flue gas expanders and compressors requiring transient waveform capture during start-stop, trip fault review and modal testing, select the transient-version A6560RT directly; no extra storage hardware installation is needed.
Q: What is the maximum measuring point capacity of one A6560R board?A: The standard configuration accommodates either one A6510 module (12 analog channels) or two A6510 modules (24 analog channels), with a fixed 2~4 tachometer input channels. Additional measuring points require extra A6560R boards and corresponding chassis slots.
Q: Can A6560R directly replace legacy AMS2600 main control boards?A: Incompatible chassis hardware prevents direct plug-in replacement. Full upgrade to AMS6500 chassis and A6510 acquisition boards is mandatory, plus upper computer software upgrade to AMS Machinery Manager V5.61 or newer.
Q: Red power indicator lit on the board with data acquisition failureA: ① Verify chassis input 24VDC power supply stays within 22~26V;
② Inspect fault LEDs on chassis power modules;
③ Power off, remove and re-seat the A6560R board to eliminate backplane finger oxidation. Persistent faults usually indicate damaged onboard power circuitry requiring factory repair.
Q: Missing vibration readings on partial channels while remaining channels operate normallyA: Fault source lies with the associated A6510 acquisition board or field sensors:
① Swap out the faulty channel’s sensor for testing;
② Interchange A6510 slot positions. Replace defective A6510 when confirmed. Zero readings across all channels denote faulty backplane bus of A6560R.
Q: Failed Modbus TCP communication with DCS and inactive Ethernet port LEDA: ① Inspect Ethernet cables for dual front/rear ports and switch ports;
② Confirm board IP matches DCS subnet and disable subnet firewall;
③ Access the board via front-panel local RS232 debug port to reconfigure Modbus register mapping.
Q: Historical data lost after network disconnection, root cause?A: A6560R relies on onboard Flash for temporary data buffering. Data loss is commonly caused by aged Flash memory or incorrect acquisition setup:
① Update onboard firmware;
② Re-enable the Offline Cache Storage parameter. Regularly back up board configuration to the host PC under extreme temperature fluctuation environments.
