Overview
The SD-DA7008/7016/7024 is a multi-channel condition monitoring system launched by SINSEGYE, designed for the non-steady-state operation characteristics of key industrial equipment. The product features 8, 16, or 24 channels for acceleration and temperature acquisition, speed measurement, and slow-variable acquisition. The system's main feature is its modular design, supporting up to 24 channels of acceleration and temperature acquisition. It can also be configured for 12 channels of slow-varying physical quantity acquisition, such as pressure, temperature, voltage, and current. The product includes two channels for speed measurement, allowing speed-correlated acquisition, and is equipped with configurable IO input and output modes.
The SD-DA7008/7016/7024 models offer the most comprehensive communication modes, supporting Ethernet, optical fiber, Wi-Fi, 4G, and other options, ensuring suitability for on-site applications. At the same time, data can be transmitted to DCS or PLC through two RS485 channels or an EtherCAT bus, truly integrating with on-site control systems. The online monitoring unit features 24-channel fully synchronous acquisition, accurately detecting equipment faults, and is a powerful tool for maintaining critical industrial equipment.

Indicator Instructions
1.RUN Indicator :
When the system is powered on, wait for about 20 seconds. If the RUN light flashes, it indicates that the system is operating normally; if it does not flash, it indicates that the system is malfunctioning.
2.COM Indicator :
When the system is powered on, the COM light stays on steadily. After about 30 seconds, the COM light starts flashing, indicating that the device is properly connected to the server. If it remains constantly on, it indicates a connection failure.
3.ERR Indicator :
Power on the system. If the ERR light remains on, wait for about 30 seconds. If the ERR light flashes, it indicates an abnormal system self-check; if it stays on continuously, it means the self-check is normal.
Monitoring unit power access (power area)
When taking the monitoring unit out of the package for the first time, check that the appearance is normal. Then connect it to an 8~36V DC power supply using P P-, paying attention to the polarity (there is polarity protection). Also, make sure the casing is connected to a protective ground for surge protection.
Monitoring unit debugging interface
Monitoring unit debugging interface (currently using a configured serial port, later to be changed to WiFi hotspot configuration)
Take out the configuration serial port from the attachment, connect one end to the PC's USB port, and connect the other end to CFG RX/CFG TX/0V. Run the serial configuration tool installed on the PC, and configure various parameters after powering on the SD-DA7000.
Wiring of acceleration measurement points for monitoring unit
The monitoring unit supports the collection of 8/16-channel integrated acceleration and temperature sensors.
The integrated accelerometer-temperature sensor is of the three-wire type and is not a PT100 type. Please consult with us in advance regarding the selection of the relevant sensors.
Buffer Variable Interface
The slow variable interface refers to certain physical interfaces for process data at the site, such as pressure, flow, torque, temperature, and other physical quantities. These physical quantities exist in the form of voltage (0~5V, 0~10V) or 4~20mA current. Voltage signals can be directly connected according to the schematics, while 4~20mA signals have three wiring methods. The monitoring unit supports 4-channel interfaces in 2-wire, 3-wire, and 4-wire configurations.
The right figure shows the wiring method for a 2-wire 4~20mA system. If it is a voltage signal, there is no need to connect to 24V; it can be connected directly to P1, P1-.
Digital input/output interface
The switch interface currently supports 4-channel IO input.
The switch input can be directly connected to D1 and D0V. The wet contact voltage supports 12~24V levels, and there is 3.5KV electrical isolation.
Other interfaces
4G interface: When choosing the 4G version, this interface needs to be connected to a 4G antenna;
WIFI interface: when selecting the WIFI version, this interface needs to be connected to the WIFI antenna;
Industrial-grade SD card interface, removable storage;
Additionally, there is a fiber optic interface and a fiber optic indicator light. When selecting the fiber optic version, this interface connects to the fiber optic cable;
