ADLINK STC-15W04 industrial tablet computer

The factory comes standard with 2GB DDR3 SO-DIMM memory, which can be expanded up to 4GB. For most standalone monitoring applications, 2GB can already run smoothly on Windows 7 Embedded or Windows 10 IoT Enterprise; If you need to run virtual machines or larger data analysis software simultaneously, it is recommended to upgrade to 4GB to reserve sufficient cache space.

3.2 Storage Solution

In terms of storage, STC-15W04 uses industrial grade CFast cards as the system disk, with a standard capacity of 8GB. CFast is based on SATA interface, which has faster read and write speed and higher reliability compared to traditional CF cards. Its industrial grade specifications can adapt to a wide temperature range of -40 ° C to+85 ° C, and have features such as power down protection and wear balance, effectively extending the life of storage media in frequent data read and write scenarios. For applications that require storage of historical data or process recipes, the device also provides an additional USB port (detailed below) that can be connected to an external USB flash drive or portable hard drive to expand capacity.

I/O interface and communication capability

4.1 Network and fieldbus interface

Dual Gigabit Ethernet ports: Equipped with Realtek 8111E controller, providing two 10/100/1000 Mbps adaptive ports. The advantage of dual network ports is that they can achieve network redundancy (such as ring network topology) or use one for connecting to the upper management network and the other for field device layer communication (such as Modbus TCP), thereby isolating data streams and improving network security.

Isolated RS-485 serial port: equipped with an electrically isolated RS-485 port, suitable for long-distance, high anti-interference fieldbus connections, and can be connected to smart instruments, frequency converters, PLCs, and other devices. Isolation design can effectively prevent signal abnormalities and equipment damage caused by ground potential differences, which is particularly important in complex industrial grounding environments.

4.2 USB and power interface

Provide two USB 2.0 ports that can be used to connect keyboards, mice, USB storage devices, or wireless network cards. Although not equipped with USB 3.0, for HMI applications, the transfer rate of USB 2.0 is sufficient for configuration file copying and firmware upgrade requirements.

The power input adopts a 3-pin DC interface with a locking mechanism, supporting 24VDC ± 15% (i.e. 20.4V~27.6V), and includes a protective grounding (PE) connection. The locking terminal ensures that the power cord will not loosen in a vibrating environment, while the polarity reversal protection function prevents equipment damage caused by misconnection. The maximum power consumption of the whole machine is only 40W, thanks to the energy-saving characteristics of the Atom platform, which also allows the system to operate under low-power switching power supplies, which is beneficial for the heat dissipation design of the control cabinet.

Strict environmental adaptability and protection level

5.1 Temperature and humidity range

The operating temperature range of STC-15W04 is from 0 ° C to 50 ° C. Although it does not reach the wide temperature range (-20 ° C~70 ° C), it is sufficient for most indoor control rooms or well shielded outdoor cabinets. Under non working conditions, it can withstand storage temperatures of -20 ° C to 60 ° C and adapt to temperature differences during transportation and storage. The relative humidity is allowed to reach up to 95% (without condensation), indicating that the internal circuit board and connectors have undergone moisture-proof treatment and can cope with high humidity areas or environments during cleaning operations.

5.2 Anti vibration and anti impact

According to the IEC 60068-2-6 standard, the equipment can withstand a vibration acceleration of 1G in the frequency range of 10Hz~500Hz, which meets the common vibration levels of industrial control cabinets. The impact tolerance meets the 15G, 11ms half sine wave specified in IEC 60068-2-27, which is sufficient to cope with the instantaneous vibration caused by mechanical impact or pipeline hammering. These parameters ensure the installation reliability of the equipment near heavy machinery such as compressors, pump sets, and fans.

5.3 Protection level and explosion-proof certification

The IP65 rating on the front panel means it is completely dust-proof and can withstand low-pressure water spray - which is extremely important in food, pharmaceutical, or chemical workshops that require regular panel flushing. The rear IP20 only protects solid objects with a diameter greater than 12.5mm, so attention should be paid to avoiding direct exposure of the rear to liquid or dust environments during installation. This is usually achieved by embedding the control cabinet panel.

The most important safety attribute is its explosion-proof certification system:

ATEX Zone 2 (EN 60079-15): Suitable for places where explosive environments rarely occur during normal operation (up to 10 hours per year).

IECEx (IEC 60079-0/15): an internationally recognized explosion-proof standard that ensures the universal compliance of equipment worldwide.
