C01 - M-Bus 10 Master to Passive RS232 Converter
- Compact M-Bus converter for up to 10 meters with a passive RS232 interface and 1kV galvanic isolation.
Product Description
The Redisage C01 is a reliable M-Bus Master converter designed to connect up to 10 M-Bus devices (such as heat, water, or electricity meters) to a passive RS232 interface. The device provides physical layer conversion while remaining fully transparent to data protocols.
Key features of the C01 model:
• Galvanic Isolation: Full circuit separation protecting the serial port from surges.
• Safety: Built-in short-circuit protection for the M-Bus line.
• Capacity: Supports up to 10 unit loads.
• Power Supply: Flexible 12-30 VDC or 24 VAC input range.
• Diagnostics: LED indicators for power status and data transmission.

About C01
C01 – Reliable M-Bus Reading for Small Systems
The C01 M-Bus Master converter is a specialized device dedicated to integrating small M-Bus networks with control systems. It is designed to handle up to 10 slave devices (unit loads), making it a cost-effective solution for single-family houses or small commercial premises where basic utility monitoring is required.
The device converts the M-Bus signal to a passive RS232 standard. This means it is optimized for short-distance communication with a local controller or PC. The converter features built-in 1kV galvanic isolation, protecting the connected control equipment from potential surges or interference originating from the M-Bus network.
Its ultra-compact 1-module housing (17.5 mm) saves valuable space in the electrical cabinet. The wide operating temperature range allows for installation in unheated technical rooms.
Technical Specifications:- M-Bus Interface: Master (supplies power to the bus), supports 10 loads.
- Output Interface: Passive RS232 (Tx, Rx, GND).
- Isolation: 1000 VDC.
- Dimensions: 98 x 17.5 x 56.4 mm (1M DIN).
The C01 is the perfect entry-level solution for M-Bus integration. For applications requiring active interfaces or RS485 support, consider the C04 model.
