C01 - M-Bus 10 Master to Passive RS232 Converter
Recommended
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 basic M-Bus Master converter designed for small-scale metering installations. It enables the reading of up to 10 M-Bus devices (such as heat, water, or electricity meters) and converts the signal to a passive RS232 interface.
This model is ideal for direct integration with PLCs or industrial computers that support passive serial connections. Key features include:
• Capacity: Up to 10 M-Bus slaves
• Interface: Passive RS232
• Isolation: 1000 VDC (galvanic separation)
• Housing: Compact DIN-rail mount (17.5 mm width)
• Operating Temperature: -40°C to +75°C

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.
