Product Summary
The A6500-UM Universal Measurement Card is a core component for the Emerson AMS 6500 ATG machinery protection system. This module provides two independent sensor input channels that interface with eddy-current, piezoelectric, seismic, and Hall-effect sensors. Engineers use this card for precise shaft vibration, case vibration, position, speed, and dynamic pressure measurements. The card transmits data via an internal RS-485 bus to the A6500-CC Com Card for conversion to Modbus protocols. This design ensures reliable integration with host computers and analysis systems for critical rotating machinery.
Theme Option A: Product Procurement & Buyer Guide
Understanding the A6500-UM Universal Measurement Card
The A6500-UM significantly reduces cabinet space requirements with its two-channel, 3U size, 1-slot plug-in design. This form factor cuts space needs in half compared to traditional four-channel 6U size cards. Procurement managers must verify that the target system rack is an A6500-xR model for proper operation. The card is API 670 compliant and features a hot-swappable module design for minimal downtime during maintenance. This compliance ensures the module meets stringent industry standards for machinery protection.
Key Technical Specifications for Selection
The card supports a wide frequency range from 0 to 18750 Hz with attenuation less than 0.1 dB. For eddy-current sensors, the input signal voltage range spans from -1 V to -22 V. The module provides a selectable supply voltage of -23.25 V or -26.0 V DC for these sensors. Application engineers must match the sensor type to the correct input channel configuration. The A6500-UM works with eddy-current, piezoelectric, seismic, LF bearing vibration, Hall-effect, and VR sensors. This flexibility makes it a universal solution for diverse monitoring needs.
Digital and Analog I/O Configuration
The A6500-UM includes five digital inputs and six digital outputs for system integration. Two of the five digital inputs can serve as key-signal inputs with a frequency range up to 2000 Hz. The module also provides two analog current outputs with a range of 0/4 to 20 mA. These outputs have a common ground and are electrically isolated from the system supply. The accuracy of these analog outputs is ±1% of full scale across the operating temperature range. This precision ensures reliable data transmission to downstream control systems.
Environmental and Certification Compliance
The card operates within a temperature range of -20°C to +70°C with forced cooling. Without forced cooling, the operating range narrows to -20°C to +55°C. The module holds a protection class of IP20 according to IEC 60529. It features a conformal coating for resistance against airborne contaminants class G3 per ISA-S71.04-1985. The A6500-UM carries multiple hazardous area approvals including ATEX, IEC-Ex, CSA, and EAC-Ex. These certifications allow deployment in Zone 2 environments with non-sparking nA nC protection.
Power Consumption and Physical Dimensions
The maximum power consumption for the A6500-UM is 6W. The board dimensions follow the PCB/EURO card format according to DIN 41494, measuring 100 x 160mm. The module weight is approximately 200g exclusive of packaging. The rack slot configuration requires a 3RU/6HP slot within the A6500-xR system rack. Engineers should verify the available power budget and physical space before procurement. This ensures seamless installation and operation within the existing system infrastructure.
