Product Details

Multi channel intelligent paperless recorderIt is a new intelligent paperless recording instrument with advanced CPU as the core, supplemented by large-scale integrated circuits, large capacity FLASH storage, intelligent signal conditioning, SmartBus bus bus, and high-resolution graphic LCD display.

Features
1. Multiple signal mixed input
Current, voltage, resistance, thermocouple, frequency and other signals can be directly input to provide sensor isolation and distribution.
2. Fully isolated input
The input signals are isolated and have strong anti-interference ability, making the instrument operation more stable and reliable.
3. Simple fault-tolerant function
When density compensation signals such as temperature and pressure are abnormal, manually set values can be applied for compensation calculations.
4. Highly reliable integrated design
Adopting hardware clock design and built-in lithium battery to ensure accurate time in case of power failure.
All parameters and recorded data are stored in FLASH memory to ensure that no data is lost after power failure.
A reliable watchdog circuit with automatic reset on and off power to ensure the normal operation of the instrument.
5. Multiple forms of compensation
Pressure compensation, temperature compensation, simultaneous temperature and pressure compensation, etc. High compensation accuracy, compensation accuracy * meets national standards.
6. Rich and intuitive display
The instrument can display all parameters and engineering units during the detection process. Over limit alarm, alarm status display.
List display, bar chart display, real-time trend display, historical curve recall.
The intelligent historical trend automatic playback function facilitates the search for alarm points and provides location query function. When directly inputted, the nearest recorded point can be found.
7. Multiple output forms
It contains multiple switch outputs and one analog output, and all switch outputs can be configured arbitrarily.
Connected with a micro printer, it can achieve paper-based printing output, with printing formats including data lists and curves.
8. Powerful communication capabilities
It can communicate with a single computer or network multiple instruments for centralized management. It can also be used as related equipment for DCS systems. All parameters and operational data can be centrally managed through computers.
9. Simple operation and application
The instrument adopts a backlit graphic LCD display, a fully Chinese human-machine interface, and a full Chinese menu operation similar to the Windows system. The configuration is simple and reliable.
Multi channel intelligent paperless recorderMain technical indicators
Input signal:
1. Analog quantity: voltage (0-2.5V) or (1-5V), current (0-10mA) or (4-20mA)
2. Thermal resistance: Cu50, Pt100, Pt1000
3. Thermoelectric coupling: E, J, K, S, T, B, etc., cold end compensation ± 1 ℃
4. Pulse quantity: waveform: rectangular wave, sine wave, or triangular wave
Amplitude: Low level (0-1V), 12VDC optional
Frequency: 0-20kHz
5. Channel input isolation:>1000V, (resistive input not isolated)
6. Sensor power distribution: 24VDC, 12VDC optional
7. Number of input channels: 1-3 channels
Output signal:
1. Analog quantity: One channel (4~mA)
2. Switching quantity: 0-4 channels, on-off two position (can be combined with three or more controls) Contact capacity: 2A, 24VDC
3. Communication interface: RS232 or RS485 baud rate: 2400, 4800, 9600, 19200bps optional
4. Paired with a micro printer to achieve paper-based printing output function;
Data recording:
1. Recording time: 0-65535 seconds, can be set by the user (0 indicates no recording), the larger the interval, the longer the total time for storing data.
2. Storage capacity: 520KdB, the length of storage time is related to the recording interval and the number of channels. Storage time: Calculated based on three channels saving data once per second, the longest data can be saved for 2 days. The storage space can be dynamically adjusted, and channels that do not record can give up space to other channels. That is, if one channel saves data once per second, it can store data for 6 days.
3. The parameters can be saved and can run for more than 10 years after power failure.
Accuracy:

Common troubleshooting:

serial number	Fault phenomenon	exclusion method
1	The whole machine is not working	Check if the power supply is correctly connected
2	Long term absence of detection data	Check if the signal connection is correct Check if the sensor is damaged Display interval set too long
3	Display incomplete data	Inaccurate setting of instrument display range
4	The display screen has no data or does not light up	Power supply disconnected The display screen is damaged
5	Record the curve (data) without change	Record interval set too large
6	History records cannot be found	Manually pressed the 'Delete All Records' menu The recording interval time has been changed
7	Printing with garbled characters	The communication baud rate is not*
