CR310 Integrated Ethernet Interface Measurement and Control Data Collector

CR310 is a versatile, compact, and low-cost measurement and control data collector that integrates Ethernet interfaces and detachable terminals. As an entry-level data collector, with its rich measurement instructions, it can measure hydrological, meteorological, environmental, and industrial sensors. The data it collects can be transmitted over the network through specified protocols and can be configured on-site or remotely. For small-scale applications that require long-term remote monitoring, CR310 is an ideal choice.

The biggest difference between CR300 and CR310 is that CR310 integrates detachable terminals and a 10/100 Ethernet interface.

CR310 has multiple radio models for different regions:

CR310-RF407: United States and Canada

CR310-RF412: Australia and New Zealand

CR310-RF422: Europe

Terminal description

A switch 12V power supply terminal (SW12V) supplies power to sensors or communication devices, 1100 mA @ 20 ° C

Two excitation terminals or 0.15 to 5 V continuous analog output terminals (VX1, VX2) are used for resistance bridge measurement or supplying power to sensors

6 multi-purpose analog input channels (SE1-SE6)

Simulation function (SE1-SE6)

Analog inputs: 6 single ended or 3 pairs of differential inputs, dual range 24 bit ADC with -100 to+2500 mV and ± 34 mV

4 to 20 mA or 0 to 20 mA input (SE1, SE2 only)

The digital I/O function (SE1-SE4) includes a 3.3V logic level:

High frequency square wave counting (35 kHz)

Pulse width modulation

Interrupt and timer inputs

Cycle average (up to 200 kHz, depending on amplitude)

Two pulse counting channels (P_SW, P_LL)

P_SW

Switching pulse (150 Hz)

High frequency square wave (35 kHz)

P_LL

Low voltage AC pulse (20 kHz)

High frequency square wave pulse (20 kHz)

Two control channels (C1, C2): Terminal C can be configured as a digital function through software

The digital I/O function includes 5V output and 3.3V logic level:

SDI-12

High frequency square wave counting (3 kHz)

Switch signal (150 Hz)

General state or control

Voltage source 5 V: 10 mA @ 3.5 Vli>

interrupt

Serial asynchronous communication Tx/Rx paired terminals

Measure and control peripheral devices

CR310 is typically not used for measuring and controlling peripheral devices due to its limited number of control ports. It is also compatible with solid-state relays with low current and voltage.

CR310 is not compatible with SDM or CDM devices.

sensor

Due to multiple channel types, cr310 is compatible with almost all available sensors. This includes analog output voltage (0-2.5V) and current (0-20mA or 4-20mA) sensors, thermistors, RTDs, and so on. It is also compatible with pulse or frequency output sensors, such as anemometers, rain gauges, and flow meters. The cr310 data collector cannot be used with reverse excitation, nor can it be used with some conductivity or soil potential sensors.

SDI-12, Modbus, and other serial sensors all support RS-232 ports and C1 and C2 as TX/RX pairs. CR310 does not directly support RS-485 sensors.

communication

CR310 can communicate with PC through USB port. Compatible telemetry devices include our RS-485 converter, digital cellular gateway, RF telemetry, and satellite transmitter. The data can be viewed on iOS devices, Android devices, or CD295 Data View II displays. Using iOS or Android devices, go to the Apple Store or Google Play to download our free login mobile application.

software

The cr300 series is compatible with Crasic (version 3.6 or higher).

energy

CR310 uses an external power source and comes with a built-in charger/regulator. Select the highest voltage from three input sources (chg, bat, or USB) and operate in one of the following four modes:

UPS (recommended) -16-32 VDC power supply, solar panels (sp10, sp20), or power converters (29796) are used to charge 12 VDC batteries, such as our BP7 or BP12.

12V DC battery or other reliable 12V DC power supply

Only chg DC power supply (16-32 vdc)

USB - USB ports exceeding 5 VDC, used for installation, programming, and testing (will not charge the battery or increase USB power, providing 12 VDC for switching battery terminals)

Envelope

The CP 10/12 or CP 12/14 casing is sufficient for most CR 310 based systems.
