Accelerometer Data Logger

AR-200 CR is a dynamic signal acquisition module for vibration monitoring and analysis. It accepts two IEPE accelerometers, each supplied with a built-in 3 mA excitation current, and digitises the signals with a 16-bit converter. Sampling of both channels runs simultaneously, at rates up to 200 kHz per channel.Recordings are written to a Micro SD card, so data can be taken away and analysed offline. Capture can be started by a push button, a schedule, an analog threshold, a digital input or a remote command from the supplied utility on a host PC, which also lets you set the sampling rate and scheduling for each application. A single relay output and one digital input add basic event handling to the unit.The logger suits panel or machine installations that need to run unattended. It works from a wide +10 to +30 VDC supply, operates from -25 to +75 °C, and provides 4 kV contact ESD protection on all terminals. Mounting is by wall or DIN-rail.ApplicationsVibration monitoring and analysisIndustrial automationFactory automationProcess automation

The AR-400 is a dynamic signal acquisition module for vibration monitoring and analysis. It samples four channels simultaneously with 16-bit resolution and supplies a built-in 3 mA excitation current for IEPE accelerometers, so compatible sensors can be connected directly without an external supply.Acquired data is written to a micro SDHC card (4 to 32 GB), allowing offline analysis after capture. Recording can be started by push button, schedule, analog threshold, digital input or remote trigger from the utility software installed on a host PC, which also handles sample rate and sampling schedule settings.Suited to condition monitoring setups where vibration data must be captured at defined times or on defined events.Includes a relay output (Form A, 5A@250 VAC) and a digital input for use within trigger or control logic.ApplicationsVibration monitoring and analysisIndustrial automationFactory automationProcess automation
