Metz 110831131970 MR-F-DI10 Modbus RTU Ψηφιακή μονάδα εισόδου

Automation engineers integrating legacy sensors into a Modbus RTU network can use the Metz MR-F-DI10 to convert 10 potential-free contact or voltage signals into register data over RS485. The module mounts on a DIN rail in a control cabinet and is configured via DIP switches.

Key specifications

• 10 digital inputs, potential-free contacts or voltage inputs (10-30 V DC)
• Modbus RTU protocol over RS485 (2-wire)
• Power supply: 10-30 V DC, max 30 mA at 24 V
• Baud rates: 9600 to 115200 bps, data formats 8N1/8E1/8O1
• Modbus address range 1-247 via DIP switches
• Isolation: 500 V DC between inputs/bus and power/bus
• Operating temperature -25 °C to +70 °C, IP20, polycarbonate housing
• LED indicators for power, bus status, and each input

Why choose it

This module provides a compact and reliable way to bring discrete signals into a Modbus RTU control system without additional programming. The wide voltage input range and isolation ensure compatibility with industrial environments.

Ideal use cases

• Connecting limit switches, pushbuttons, or relay contacts to a PLC or SCADA system
• Monitoring status signals in building automation or machine control
• Retrofitting existing equipment with Modbus communication

Good to know

Configuration is done via DIP switches, so no software tool is needed. The module is designed for DIN rail mounting (EN 60715).
