MODBUS RTU Databox for MICROTECH USB‑C Instruments, RS‑485 Output, IP40 - Microtech Metrology

Take advantage of a compact, standards‑based interface that converts MICROTECH DataMet USB‑C outputs into Modbus RTU over RS‑485, ensuring stable industrial data transmission and simple integration into existing control systems; order the Modbus RTU data box directly via Metav Werkzeuge or ask our consultants if needed.

Modbus RTU data box — Industrial Modbus RTU interface with RS‑485 and USB‑C

The Modbus RTU data box is a compact interface module that links MICROTECH DataMet instruments to industrial networks, converting USB‑C sensor outputs into a configurable Modbus RTU stream for process monitoring and data logging.

• Industrial Modbus RTU interface
• RS‑485, 4‑wire connection
• USB‑C for Microtech DataMet instruments
• Compact IP40 enclosure 53×82×31 mm

Seamless, standards‑based data transfer for reliable process control

The interface module provides Modbus RTU communication on an RS‑485 physical layer, enabling deterministic transfer of measurement data into PLCs, SCADA systems or data loggers. With a default baud rate of 9600 bps (configurable), 8 data bits, 1 stop bit and no parity, the module follows established serial communication rules so integration is predictable and repeatable. For production environments this means fewer configuration cycles and faster commissioning, because common communication parameters are already supported by most industrial controllers. The combination of protocol conformity and USB‑C connectivity to MICROTECH DataMet instruments reduces conversion effort and preserves measurement integrity when bridging laboratory devices and automation networks.

Compact construction that suits tight spaces while withstanding shop conditions

Measuring 53×82×31 mm and weighing just 0.15 kg, the device fits into compact enclosures or close to measurement points to shorten cable runs and reduce routing complexity. The IP40 rated enclosure protects electronics against typical workshop dust ingress while the permitted operating range of 5–40 °C and 70% humidity covers most factory and bench environments. The small footprint supports tidy installations and easier cable management, which in turn helps maintain signal quality and lowers the chance of intermittent faults caused by strained wiring. For system integrators and test stations, the result is a reliable link with minimal installation overhead.

Simple configuration and transparent technical behaviour for straightforward integration

Configuration follows the familiar Modbus RTU paradigm: set the baud rate, address and frame parameters on the host or via controller tools and the interface relays measurement frames across the RS‑485, 4‑wire output (pins: 5–24 V supply, GND, A, B). Explaining the protocol in practical terms: Modbus RTU packages numeric measurements into registers that controllers read cyclically — a robust, widely supported mechanism that keeps polling intervals predictable. The unit is supplied without a measuring instrument, so it partners with existing MICROTECH DataMet devices via USB‑C; this separation ensures flexibility when upgrading measurement hardware or changing network architecture without replacing the conversion module.

FAQ

How does the module connect to MICROTECH DataMet instruments?
The Modbus RTU data box connects to MICROTECH DataMet instruments via a USB‑C interface on the device side and provides a Modbus RTU stream on the RS‑485 output for integration into control systems.

Which communication settings are required for integration?
Standard Modbus RTU parameters apply: 9600 bps (configurable), 8 data bits, 1 stop bit and no parity; these settings are compatible with most PLCs and data loggers.

Is the unit suitable for harsh industrial environments?
The enclosure is rated IP40 and the permitted operating temperature is 5–40 °C with up to 70% humidity; the device is designed for typical shopfloor and laboratory conditions but not for direct water exposure.

Does the delivery include a measuring instrument or sensor?
No; the product is supplied without a measuring instrument and is intended to be used with existing MICROTECH DataMet devices connected via USB‑C.
