Overview The CR300 is a multi-purpose, compact measurement and control datalogger. This small, low-cost, high-value datalogger offers fast communications, low power requirements, built-in USB, and excellent analog input accuracy and resolution. The CR300 can measure most hydrological, meteorological, environmental, and industrial sensors.
It concentrates data, makes it available over varied networks, and delivers it using your preferred protocol. It also performs automated on-site or remote decision making for control and M2M communications.
The CR300 is ideal for small applications requiring long-term remote monitoring and control. Autodesk Building Design Suite Ultimate 2013 Full Download here. The CR300 series includes Wi-Fi, cellular, or the following radio options for different regions: • CR300-RF407: US and Canada • CR300-RF412: Australia and New Zealand • CR300-RF422: Europe. NOTE- Additional specifications are listed in the. Operating Temperature Range -40° to +70°C (standard) Analog Inputs 6 single-ended or 3 differential (individually configured) Pulse Counters 8 (P_SW, P_LL, C1, C2, and SE1 to SE4) Voltage Excitation Terminals 2 (VX1, VX2) Communications Ports • USB • RS-232 Switched 12 Volt 1 terminal Digital I/O 7 terminals (C1, C2, P_SW, and SE1 to SE4) configurable for digital input and output.
Includes status high/low, pulse width modulation, external interrupt, and communication functions. Input Limits -100 mV to +2500 mV Analog Voltage Accuracy • Accuracy specifications do not include sensor or measurement noise. • ±(0.04% of measurement + offset) at 0° to 40°C • ±(0.1% of measurement + offset) at -40° to +70°C ADC 24-bit Power Requirements 10 to 18 Vdc; 16 to 32 Vdc Real-Time Clock Accuracy ±1 min. Sensors With several channel types, the CR300 is compatible with nearly every available sensor. This includes analog output voltage (0 to 2.5 V) and current (0 to 20 mA or 4 to 20 mA) sensors, thermistors, and RTDs to name a few. It is also compatible with pulse or frequency output sensors such as anemometers, rain gauges, and flow meters.
SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR300 does not directly support RS-485 sensors.
Measurement & Control Peripherals The CR300 is compatible with low current and voltage solid-statey relays but not with SDM or CDM devices. Communications The CR300 can communicate with a PC directly via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters (HDR GOES, Argos, Meteosat, Iridium, and Inmarsat).
Data can be viewed on an iOS or Android device (requires our free LoggerLink app), CD295 DataView II Display, or other third-party devices. Oxmo Puccino L Amour Est Mort Rar. Datalogger Option Communications Type Integrated Communications Are Compatible with CR300-WIFI 2.4 GHz, 20 MHz bandwidth Most other Wi-Fi devices, such as the,, CR300-RF407 902 to 928 MHz Frequency Hopping Spread Spectrum,, CR300-RF412 915 to 928 MHz Frequency Hopping Spread Spectrum,, CR300-RF422 868 MHz SRD860 LBT+AFA,, CR300-CELL 2G Frequency Bands 850, 900, 1800, 1900 3G Frequency Bands 800, 850, 900, 1900, 2100 GSM/GPRS/EDGE (2G) UMTS/HSPA+ (3G). Power The CR300 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (CHG, BAT, or USB) to operate in one of the following four modes: • UPS (recommended) - A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter (29796) is used to charge a 12 Vdc battery, such as our BP7 or BP12.
