Function Introduction
Universal signal input (isolated type)
The data logger is designed with a maximum of 6 universal signal input channels, supporting mV, V, mA, resistance thermometer, and thermocouple signals. The channel signal type is configured through input settings. The data logger automatically switches to the corresponding acquisition circuit based on the configured signal type, with a signal acquisition cycle of 1 second.
Each channel can be independently configured with parameters such as unit, range, decimal places, adjustment, filtering, open-circuit detection, and small signal suppression.
Data recording and alarming, power failure detection, and log recording.
The data logger records channel sampling data in real time according to the system configuration settings, with selectable recording intervals: 1 second, 2 seconds, 5 seconds, 10 seconds, 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 30 minutes, and 1 hour. The data logger has 16MB of internal memory, capable of storing 900,000 records. With a 6-channel, 1-second recording interval, it can store data for 10 days; increasing the recording interval will correspondingly increase the recording period. The data logger also simultaneously records channel alarms, instrument power failures, and operation log information, with 256 records for each type, using a circular overwrite storage mode.

Alarm relay output
The recorder is designed with a maximum of 6 alarm relay outputs, and the relays are of the normally open type. Through alarm configuration settings, the relay contacts can be arbitrarily assigned to specific channels. Four types of alarms can be set: high alarm, low alarm, high-high alarm, and low-low alarm. Alarm hysteresis and relay delay parameters can also be configured.
24VDC sensor power distribution
The data logger is configured with two 24VDC power supply outputs for powering sensors. It can directly drive two-wire sensors, with the current loop connected in series with the data logger’s input channel.
4-20mA transmitter output
The data logger can be optionally equipped with up to two 4-20mA transmitter output channels, and the transmission relationship between the output and input channels can be configured through the output configuration settings.
RS485 communication interface
The data logger is equipped with one RS485 communication interface, using the standard MODBUS RTU communication protocol in slave mode, enabling external data communication and transmission. It supports real-time channel data and channel alarm status data, and provides 32-bit integer and 32-bit floating-point data types. The communication baud rate and byte order are configurable.
Miniature printer interface
An optional miniature printer interface is available, enabling automatic real-time printing of data and curves, as well as manual printing of historical data and curves.
USB data backup
The data logger is equipped with a USB 2.0 interface, allowing for manual export of historical data to a USB flash drive via the USB port, and automatic scheduled backup of historical data.
Automatic printing interface
Manual printing interface
Configuration import and firmware update
It supports importing and exporting configuration parameters and updating instrument firmware via the USB interface.
Cumulative flow rate (without temperature and pressure compensation)
The data logger supports channel flow accumulation but does not have temperature and pressure compensation functions.
Vacuum level calculation algorithm
The data logger supports channel vacuum level algorithms, and, in conjunction with the vacuum gauge output signal, calculates, stores, and displays data in terms of vacuum level.
Upper-level computer data management software
The data logger comes with accompanying PC-based data management software, which supports viewing and exporting data from USB drives, and also supports real-time data monitoring on a single computer. It supports both graphical and tabular data display modes and can export data to Excel reports.
