About Synchronous Devices for Measurement

Synchronous Devices for Measurement (SDMs) are a group of addressable peripherals that expand the datalogger's output and measurement capabilities. The datalogger controls the SDM output device by storing a value in a memory location, which is then used by the SDM to set a voltage or relay.

Number of FAQs related to Synchronous Devices for Measurement: 1

Are the CR200X, CR206X, CR211X, CR216X, or CR295X dataloggers compatible with SDMs and multiplexers?

The CR200X-series and the retired CR200-series dataloggers are NOT compatible with SDMs or multiplexers. If more channels are needed or may be needed in the future, consider purchasing a CR800, CR850, or CR1000 instead.
