The 86517-01-01-01-02 operates on a -23 to -26 Vdc supply, drawing only 22 mA. Its charge amplifier provides a low frequency -3 dB corner at 4.7 Hz and high frequency response up to 5000 Hz with typical 1000 pF accelerometer and cable capacitance.
Industry Applications
This module is ideal for upgrading older vibration monitoring systems in turbines, compressors, pumps, and motors. With the 86517-01-01-01-02, you can replace obsolete interface cards while maintaining compatibility with existing 50 pC/g accelerometers. Its CENELEC approval suits hazardous area installations requiring intrinsic safety barriers.
Installation & Setup Guidance
Mount the 86517-01-01-01-02 using two 8-32 allen head bolts at opposite corners of a 4.45 by 2.05 inch rectangle. Ensure the module is isolated from ground to prevent ground loops. Connect the accelerometer via the MS-3112-8-3P connector. Power and output signals connect to the 8-lug terminal block. Verify supply voltage between -23 and -26 Vdc before powering.
Maintenance & Reliability
Operating temperature range of 0°C to 70°C and storage from -40°C to +85°C make the 86517-01-01-01-02 suitable for harsh industrial environments. Humidity tolerance up to 95% noncondensing ensures reliable performance. No routine calibration is required beyond verifying output accuracy per the ±5% specification.
Selection Guide & Purchasing Advice
When selecting the 86517-01-01-01-02, confirm your accelerometer sensitivity matches the 50 pC/g option. The interface module does not include accelerometers or cables. For replacement applications, verify the existing wiring matches the 8-lug terminal block.
