CR310-WiFi Datalogger with Ethernet

CR300 and CR310

The primary differences between the CR300 and the CR310 are that the CR310 offers removable connectors and a 10/100 Ethernet connection.

The CR310 has several radio options suited to different regions:

• CR310-RF407: US and Canada
• CR310-RF412: Australia and New Zealand
• CR310-RF422: Europe

Benefits and features

• Easy setup with PC software and USB connectivity
• Confident measurement of analog and digital sensors
• Internet ready: email, FTP, HTTP/web and TCP, with the required add-ons
• Campbell Scientific quality, including integral surge and ESD protection
• Money and space saved with the integrated Ethernet port
• Wireless networking to another node or an Internet gateway through the integrated radio option
• CR310-WIFI, ideal for short-range wireless IP communication
• Easy wiring through the removable terminal block
• Communication from anywhere with a cellular or satellite peripheral
• Battery charging with the integrated 12 V battery solar charge regulator
• Smart sensor measurement over RS-232 or SDI-12
• Connection through PakBus, Modbus, DNP3, GOES and other standard communication protocols
• Analysis and control with programmability and multiple general-purpose I/O
• Notification through event-driven communications and physical outputs

Detailed description

• One switched 12 V terminal (SW12V) for powering sensors or communication devices: 1100 mA @ 20°C
• Two sensor excitation or continuous 0.15 to 5 V terminals (VX1, VX2) for sensor excitation or output control
• Six multipurpose analog input terminals (SE1 – SE6)

Analog functions (SE1 – SE6)

• Analog inputs: 6 single-ended or 3 differential inputs with -100 to +2500 mV and ±34 mV ranges; 24 bit ADC
• 4 to 20 mA or 0 to 20 mA inputs (SE1, SE2 only)

Digital I/O functions (SE1 – SE4), with 3.3 V logic levels

• High frequency counter (35 kHz)
• Pulse width modulation
• Interrupts and timer input
• Period average (200 kHz, amplitude dependent)

Two pulse counting terminals (P_SW, P_LL)

• P_SW: switch closure (150 Hz) and high frequency counter (35 kHz)
• P_LL: low level ac (20 kHz) and high frequency counter (20 kHz)

Two control terminals (C1, C2)

C terminals are software configurable for digital functions. Their digital I/O functions have 5 V output and 3.3 V input logic levels for:

• SDI-12
• High frequency counter (3 kHz)
• Switch closure (150 Hz)
• General status/control
• Voltage source 5 V: 10 mA @ 3.5 V
• Interrupts
• Serial asynchronous communication Tx/Rx pair

Compatibility

The CR310 is typically not used with measurement and control peripherals because of its limited number of control ports. It is also compatible with low on-current and voltage solid-state relays.

The CR310 is not compatible with SDM or CDM devices.

Sensors

With several channel types, the CR310 is compatible with nearly every available sensor, including 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 also works with pulse or frequency output sensors such as anemometers, rain gauges and flow meters. SDI-12, Modbus and other serial sensors are supported through the RS-232 port and through C1 and C2 as a Tx/Rx pair. The CR300 does not directly support RS-485 sensors.

Communications

The CR310 communicates with a PC through its USB port. Compatible telemetry devices include RS-485 converters, digital cellular gateways, RF telemetry and satellite transmitters. Data can be viewed on an iOS or Android device, or on the CD295 DataView II display. To use an iOS or Android device, go to the Apple Store or Google Play and download the free LoggerLink Mobile app.
