Compact M-Bus pulse adapter for integrating meters with pulse output into metering systems – IM001GC

IM001GC – compact M-Bus pulse adapter for integrating meters with pulse output.

IM001GC (PadPuls M1 Compact) is a compact M-Bus pulse adapter designed to integrate meters equipped with pulse output (potential-free contact) into M-Bus-based metering systems. It enables reliable connection of electricity, water, gas, heat or oil meters to centralized monitoring and billing infrastructures without replacing existing metering devices.

Key product features

• Integration of pulse-output meters into M-Bus systems
• Support for potential-free pulse contacts (reed contact)
• Powered directly via the M-Bus line
• Integrated backup battery for uninterrupted pulse counting
• Long battery lifetime of several years
• Flexible configuration of pulse parameters via software
• Protection against unauthorized configuration changes
• Compact enclosure for space-saving installation

Operating principle

IM001GC counts pulses generated by the connected meter and converts them into M-Bus readable data. The accumulated values can be read at any time by an M-Bus master or data logger. Communication is compliant with EN 1434-3 and the device automatically detects the M-Bus baud rate.

Differences between IM001G and IM001GC

• IM001G – version in a larger enclosure for wall mounting
• IM001GC – compact version designed for installation directly near the meter
• IM001GC requires less installation space and is ideal for tight meter cabinets
• Both versions are functionally equivalent; the difference is limited to housing and mounting concept

Data security and reliability

IM001GC includes a configuration lock mechanism that prevents parameter changes after commissioning without physical access to the sealed enclosure. The integrated battery ensures continuous pulse counting even during extended M-Bus power outages.

Applications

IM001GC is particularly well suited for retrofit projects where pulse-output meters need to be integrated into modern M-Bus infrastructures and installation space is limited. Typical applications include residential buildings, commercial facilities and industrial metering systems.

IM001GC is a compact and reliable M-Bus pulse adapter that enables seamless integration of pulse-output meters in space-constrained installations. It offers the same functionality as the IM001G model while providing a smaller form factor for greater installation flexibility.
