The M-Net interface model PAC-YG66MCA is a digital sensor input/output acquisition device for installation on the wall or in a control cabinet.

The interface is directly connected to the M-Net network (TB3-TB7), and occupies an address similar to the indoor units (01-50) for each connected technological equipment (max. 6 equipment).

Each technological equipment can present:

• No. 1 output ON/OFF command
• No. 1 input ON/OFF status
• No. 1 input malfunction state

A 3D Web Server centralizer (TOUCH or BLIND), and possibly a supervisory system, is indispensable for the use of the interface.

Available functions are:

• Displaying input ON/OFF status or malfunction
• Command output ON/OFF
• Interlock with air conditioner functions
• Interlocking with other digital inputs/outputs, including other interfaces
• Icons representation on graphic floor plan
.

The interface has an integrated on-board relay and terminal blocks for two devices.

For the next four, two accessories model PAC-YG10HA must be provided.

These accessories make signals available with "open collector" transistor output, so the connection terminal block and control relays must be made separately.

The M-Net interfaces have been developed to enable the connection of external signals of various kinds to the MELANS management and supervision system, both input and output, i.e., monitoring and control.

The interfaces are connected directly to the M-Net data transmission bus.

Thanks to their modularity, and it is possible to connect multiple interfaces on the same network.

To connect the interfaces, it is necessary to provide 24VDC auxiliary power supply with a separate locally supplied power supply.

The following M-Net interfaces are available:

• PAC-YG60MCA: Digital counter interface (Pulse Input).
• PAC-YG63MCA: Analog sensor interface (Analog Input).
• PAC-YG66DCA: Digital Sensor Interface (DIDO).
