53x82x31 mm Modbus RTU Data Box IP40, RS‑485 Microtech Metrology

Compact industrial gateway converts USB‑C metrology outputs to Modbus RTU over RS‑485, with configurable serial settings and an IP40 enclosure — ideal for integrating laboratory-grade measuring instruments into process control. Benefit from reliable protocol compatibility and a small footprint; order the module directly via Metav Werkzeuge or consult the Metav specialists for integration advice.

Modbus RTU Data Box (Microtech Metrology) — RS‑485 gateway for DataMet instruments

The Modbus RTU Data Box links Microtech DataMet instruments to industrial controllers and SCADA environments, providing a robust serial bridge for continuous data transfer and machine‑level integration.

• Modbus RTU protocol for industrial integration
• RS‑485 4‑wire interface (A, B, GND, 5–24 V)
• Compact IP40 enclosure, 53 × 82 × 31 mm

Seamless system integration for process control

This Modbus RTU interface simplifies the transfer of measurement values from laboratory instruments into automation systems, enabling direct connection to PLCs and data loggers via RS‑485. With a hardwareised serial bridge designed for deterministic communication, commissioning time is reduced: the default 9600 bps setting offers immediate compatibility with many legacy systems while the configurable baud rate ensures adaptation to faster networks. The result is a predictable, industrial‑grade data path that supports traceable processes and reduces manual transcription.

Small footprint, industrial robustness

Housed in a compact enclosure of 53 × 82 × 31 mm, the unit occupies minimal panel space while delivering the mechanical stability required for measurement setups. The IP40 rating and specified operating range keep the interface suitable for indoor workshop and laboratory environments where protection against coarse particles and controlled humidity is sufficient. The lightweight construction (approx. 0.15 kg) aids neat mounting and tidy cable routing without adding bulk to measurement stations.

Clear serial parameters for dependable transfers

Serial communications are framed to industry norms: default 9600 bps, 8 data bits, 1 stop bit and no parity, which together provide a standardised data format that simplifies protocol stacks on PLCs and SCADA systems. Clear, documented settings reduce ambiguity during integration and help maintain data integrity across longer RS‑485 bus runs. The four‑wire RS‑485 connection (power line plus A/B pair and ground) supports stable signalling for multi‑drop topologies.

Built to fit metrology workflows

Designed specifically for use with Microtech measurement equipment, the module accepts USB‑C input from DataMet instruments and converts that stream into a field‑ready Modbus RTU signal. The unit is supplied without a measuring tool and therefore complements existing instrument fleets rather than replacing them. Rated for operation between 5–40 °C and up to 70 % relative humidity, the interface is tailored to the ambient conditions typical of inspection benches and machine shops, helping to extend the utility of precision instruments into live production monitoring.

FAQ

Is Modbus RTU the only supported protocol?
The Modbus RTU data box from Microtech Metrology supports the Modbus RTU protocol for industrial integration; it is designed specifically to provide a Modbus RTU output from compatible DataMet instruments (SKU 141077071).

Can the module be connected directly to a PLC RS‑485 port?
Yes; the device provides a four‑wire RS‑485 interface (A, B, GND, and a 5–24 V supply line) for direct connection to PLC fieldbus ports or RS‑485 gateways using standard cabling.

Is the unit suitable for outdoor use or wet environments?
No; the enclosure is rated IP40, which protects against solid objects but is not intended for wet or outdoor locations. The product is intended for controlled indoor environments.

Are the serial settings changeable on site?
Yes; the default 9600 bps can be reconfigured where required, and standard framing parameters (8 data bits, 1 stop bit, no parity) are provided to ensure compatibility with most automation systems.

Does the delivery include a measuring instrument or calibration certificate?
The Modbus RTU data box is supplied without a measuring tool; it operates as an interface for Microtech DataMet instruments and does not include calibration documentation for measuring devices.
