OrbitDCM
Newest addition to theCordant™ Machine Healthsuite of products
A powerful, advanced edge device
for Distributed Condition Monitoring(DCM) with plantwide connectivity
and asset health management
Bently Nevada’s new Orbit DCM device is a flexible andscalable system fully supported by our System 1 condition
monitoring and diagnostic software. It delivers economic
vibration monitoring along with Bently Nevada’s reliable
signal processing for important assets.

Key features

With high-speed data collection, processing on the edge,
and synchronous data acquisition across all 16 channels,
Orbit DCM gives operators the machine health insights theyneed to succeed.

• Cybersecure

Machinery applications
Orbit DCM is an ideal condition monitoring instrument formachinery with rolling element bearings and complex
gearboxes, including:• Agitators• Mill stands• Air compressors• Motors• Blowers• Paper machines• Centrifuges• Pumps• Cooling tower fans andpumps• Small centrifugalcompressors• Extruders• Wind turbine generators• Machine tool spindles

System 1 enables strategic, data-driven maintenanceplanning and decision-making to optimize asset reliability.
• Compact and easy to install• Simultaneous 16-channel data sampling, 4 digital inputs• Configurable channels support a variety of transducers• Four keyphasor channels for synchronous sampling• Support for use with single PC or network• Three wired ethernet connections• RS485 interface for serial communication• 24-bit A/D conversion with high precision• Offline data storage on communication loss
• Direct support for two-wire IEPE/ICP accelerometers up to
10 mA and indirect for most other sensing types• Multiple user-configurable waveforms per channel• Configurable setpoints with alarming and events• Data storage and alarming based on machine
operating state• Built-in modbus (server & client) support (RTU, TCP)
• High resolution data collection for alarm and transientsThe Orbit DCM and System 1 software complement yourpredictive maintenance program by performing costeffective data collection and condition monitoring analysis.
System 1 is at the core of all our condition monitoring
solutions—providing an innovative, single ecosystem for fullplant-wide machinery management.
