Modular Central Data Acquisition Host

Most off-the-shelf data acquisition units force a choice between channel count and compatibility. Kingmach’s modular central data acquisition host sidesteps that. You start with a mainboard that handles standard digital and analog inputs, then snap in modules for vibrating wire, SDI-12, or relay outputs as needed. The electrical design keeps noise low enough that you can run cable lengths over 500 m with vibrating wire sensors without losing signal integrity—something serious monitoring projects often demand. Internally, the host runs an industrial ARM processor paired with a Linux OS, which means it can handle edge computing tasks like data logging, basic alarming, and protocol conversion locally. That reduces the traffic you send to the cloud and keeps the system working even if the connection drops. For communication, you get options: built-in 4G (with global band support), Ethernet, RS485, and LoRa are typical. The firmware supports standard protocols such as Modbus TCP/RTU, MQTT, and FTP push, so integrating with third-party SCADA or cloud platforms isn’t a custom development job each time. Storage is solid—usually a 16 GB industrial-grade SD card that can hold months of 5-minute data from over 100 channels. Remote firmware upgrades are possible, and Kingmach provides a configuration utility that doesn’t require you to write scripts. Power wise, the host can run from 9–36 V DC, and a properly sized solar panel keeps it going in the field. Temperature range is typically -20 to 70 °C, tested for humidity and dust (IP rating around 65). Kingmach, as a specialist in geotechnical instruments, also ensures that the host works natively with its own line of sensors—vibrating wire piezometers, inclinometer chains, crack meters, you name it—but it’s also tested with common third-party brands. Customization is possible: if your project needs a specific protocol or a non-standard channel arrangement, the engineering team can tweak the firmware and hardware layout. This isn’t a box you buy off the shelf—you get it configured for your monitoring plan, with wiring diagrams and a test report. Global shipping and technical support are standard, and the manual is in clear English with functional diagrams, not just a translated spec sheet.
