Acrel DC AGF-M24T Multi-Circuits Monitoring Device With RS485 35mm DIN Rail LCD Power Monitoring Module Energy Metering Module

PAPER CARTON

General

AGF-T Perforation type PV confluence acquisition device is specially designed for smart PV combiner box. It is used for monitoring the running state of solar panels in solar cell arrays, measuring the currents of solar cell, detecting the state of surge protection devices and DC breaker. The device is equipped with RS485(Modbus) communication port for transmitting all the datas to master device.

Connections of modules

Data cable connection way

The connection between each module is through the external data line. Please confirm the 

sequence of the two external data line ports before connecting each module. Each confluence 

acquisition module has two outside connection ports(Figure 4): Port I and Port II, in which Port I is used 

to connect upstream module and Port II is used to connect follow-up modules. Please pay attention to it 

that the propulsion part of the data line connector must be fixed with the groove on the port. 

The connection sequence order of PV confluence acquisition modules must follow: confluence 

acquisition module 1’s port Ⅱ-->confluence acquisition module 2’s port Ⅰ , 

confluence acquisition module 2’s port Ⅱ-->confluence acquisition module 3’s port Ⅰ . 

When connecting the confluence acquisition modules ,multiple confluence modules should be in 

sequence order, it is not allowed to insert any other function module between two sequenced confluence 

modules. Wrong connection will lead to abnormal operation of the device. 

LCD display module can be connected with Port II of confluence acquisition module, The LCD 

display module is not necessary to be connected in at ordinary time except when testing and checking. 

The address allocation of PV confluence acquisition module is automatically distributed by the 

power module(main module), The first confluence acquisition module connected to the power module 

will be distributed automatically with 1st to 8th channels, and the next confluence acquisition module 

connected to port II will be distributed automatically with 9th to 16th channels, the final confluence 

acquisition module is distributed automatically with 17th to 24th channel.

Note: The arrow shows current direction. Wrong connection will lead to abnormal operation of the device.

Definition of input port

After the address of confluence acquisition module is distributed by the main module，the input 

channel address of first module is from 1st to 8th channel，the input channel address of second 

confluence acquisition module is from 9th to 16th channel，the input channel address of final confluence 

acquisition module is from 17th to 24th channel. The input channel definition of 1st to 8th channel of a 

single module is shown as Figure 3.
