# Data Logger, AC Voltage & Current **URL**: https://novapart.co/products/OMYL-M33/data-logger-ac-voltage-current **SKU**: OMYL-M33 **Manufacturer**: OMEGA **Price**: €636.8100 **Stock**: 10+ **Lead Time**: 281 days (indicative) ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (04-Feb-2026) | | Product Range | OM-PR Series | | Data Logger Type | AC Voltage & Current | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3907343/) ## _**Process Voltage/Current Input Data Loggers**_ ## **OMYL-M33 and OMYL-M34** ## U **Single Channel (OMYL-M33) or Dual Channel (OMYL-M34)** - U **Process Voltage and Current Measurements** - U **Up to 4 Million Readings (Internal Memory Size)** - U **Up to 32 Hz Sampling Rate** - U **High Accuracy** **OMYL-M33 shown larger than actual size.** - U **20 Bit A/D Converter** - U **Shock Proof, IP65 Housing (Dust and Water Jet Proof)** - U **Transfer Rate of 500 kbps** - U **Low Current Consumption** - U **Up to 4 Years Battery Life** The OMYL-M33 single channel and OMYL-M34 dual channel process voltage/current input data loggers are fully user programmable for 0 to 1V, 0 to 5V, 0 to 10V and 4 to 20 mA industry standard process input ranges. These data loggers are available with standard memory of 100,000 readings (OMYL-M33, OMYL-M34) or expanded memory of 4 million readings (OMYL-M33-4M, OMYL-M34-4M). Both models can be used for recording signals from a wide range of process transducers and transmitters. These devices are programmable so that you can log data from either one or two channels. Both models feature a 20 bit analog to digital converter giving a resolution of up to 15 µV or 0.36 µA. The storage medium is non-volatile flash memory so no data is lost if the battery becomes discharged. Data logger setup as well as data retrieval is accomplished using the included standard OMYL-SOFT software. Downloaded data is stored in the OMYL-SOFT software as a text file for viewing in third party software packages or Microsoft Excel. The OMYL-SOFT standard software does not include any graphing functionality. Graphing and analyzing downloaded data files requires the OMYL-SOFT-PLUS version of the software (sold separately). **OMYL-M34 shown larger than actual size.** |**Input Ranges***|**Input Ranges***|**Input Ranges***|**Input Ranges***|**Input Ranges***|**Input Ranges***| |---|---|---|---|---|---| |**Range**|0 to 1V|0 to 2.5V|0 to 5V|0 to 10V|0 to 24 mA| |**Resolution(µV)**|15.4|38.9|76.9|154|0.36µA| |**Input**
