Overview

The CR310 is a multi-purpose, compact, low-cost measurement and control data logger that includes an integrated 10/100 Ethernet port and removable terminal connectors. This entry-level data logger, with its rich instruction set, can measure most hydrological, meteorological, environmental, and industrial sensors. It concentrates and makes data available over varied networks, with delivery using your preferred protocol. The CR310 also performs automated on-site or remote decision-making for control and M2M communications. The CR310 is ideal for small applications requiring long-term, remote monitoring and control.

The CR310 has multiple radio options that are suitable for different regions:

CR310-RF407: US and Canada
CR310-RF412: Australia and New Zealand
CR310-RF422: UK and EU
CR310-RF427: Brazil

Note: Campbell Scientific does not recommend the CR310 for use as a PakBus router in networks with more than 50 devices. Large arrays or string variables may also reach memory limits. For such applications, a CR1000Xe Measurement and Control Datalogger is recommended.

Compatibility

Measurement & Control Peripherals

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. 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. CR310 dataloggers are not capable of applying reverse excitation, and they cannot be used with some conductivity or soil matric potential sensors.

SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR310 does not directly support RS-485 sensors.

Communications

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

Software

The CR300 series is compatible with CRBasic (version 3.6 or higher).

Power

The CR310 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.
12 Vdc battery or other reliable 12 Vdc source
Chg only - DC power supply (16 to 32 Vdc)
USB - Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the switched battery terminal SW12)
