IM003GCB - Battery-powered two-channel M-Bus pulse converter for DIN rail mounting

IM003GCB – battery-powered two-channel M-Bus pulse converter for DIN rail mounting.

IM003GCB (PadPuls M2CV) is a battery-powered two-channel M-Bus pulse converter designed to integrate meters equipped with floating pulse outputs or S0 interfaces into M-Bus-based metering systems. The device enables connection of up to two pulse-output meters in installations where power supply from the M-Bus line is unavailable or not desired.

Key product features

• Integration of up to two pulse-output meters
• Two independent channels – each operating as a separate M-Bus slave
• Battery-powered operation – no power consumption from the M-Bus line
• Long battery lifetime for autonomous multi-year operation
• Support for floating pulse outputs and electronic S0 interfaces
• Optional tariff mode (primary and secondary tariff)
• Due-date (billing date) function
• DIN rail mounting (DIN EN 50022, 3TE)

Operating principle

IM003GCB counts pulses generated by connected meters and provides the data via the M-Bus protocol. Each channel has its own primary and secondary M-Bus address, allowing independent readout of each meter. Communication complies with EN 1434-3 and features automatic baud rate detection.

Tariff mode and billing functions

In tariff mode, pulses from a single meter can be recorded separately for primary and secondary tariffs. Tariff switching is performed using an external signal, for example from a utility control system. The integrated real-time clock enables automatic storage of billing values without the need for additional software.

Reliability and data integrity

Thanks to battery-powered operation, IM003GCB remains fully functional regardless of the M-Bus line status. Meter readings are periodically stored in non-volatile memory, ensuring high resistance to data loss even during long communication interruptions.

Applications

IM003GCB is suitable for residential, commercial and industrial metering systems where DIN rail mounting and independence from M-Bus power are required. It is particularly recommended for retrofit projects and installations with limited access to the M-Bus power supply.

IM003GCB is a reliable battery-powered two-channel M-Bus pulse converter for DIN rail mounting, combining flexible installation, autonomous operation and advanced tariff and billing functions. It is a robust solution for professional M-Bus metering systems.
