M-NET Interfaces

M-Net interfaces were developed to permit the connection of a wide variety of input and output signals (i.e. for monitoring and control) to the MELANS management and supervision system. These interfaces are connected directly to the M-Net data transmission bus. The modular concept of these interfaces means that multiple interfaces can be connected to the same network. To connect interfaces, a 24V DC auxiliary power feed must be provided with an additional power supply unit (purchased separately). The following M-Net interfaces are available:

• PAC-YG60MCA: Digital meter interface (Pulse Input).
• PAC-YG63MCA: Analogue sensor interface (Analogue Input).
• PAC-YG66DCA: Digital sensor interface (DIDO).

PAC-YG60MCA – Pulse Input

The PAC-YG60MCA M-Net interface is a device for acquiring the output signals from wall or electrical cabinet mounted digital impulse consumption meters. This interface makes it possible to monitor the consumption of the installation with any electric power (WHM), water, and gas consumption meters and calorimeters producing an impulse type output signal. Up to 4 digital meters may be connected to each individual interface. In order to use the interface, a WEB Server 3D (TOUCH or BLIND) centralised controller must be included in the installation to monitor the status of the system and enable the following functions:

• View real time consumption values
• View consumption graphs
• Export consumption billing data in CSV format for consumption apportioning (CHARGE).
