Installation

3.1 Installation Sequence
All distributed controllers and I/O modules from Beilai Technology must be mounted on a standard DIN 35 rail.
Starting from the controller, the I/O modules are assembled from left to right, and the modules are installed next to each other. All I/O modules have grooves and power jumper contacts on the right side, to avoid assembly errors, I/O modules must be inserted from the right and top to avoid damage to the modules.
Utilizes a tongue and groove system to form a secure fit and connection. With the automatic locking function, the individual components are securely fixed on the rail after installation.
Don’t forget to install the terminal module! Always plug a terminal module (eg TERM) into the end of the I/O module to ensure correct data transmission.

3.2 Install Controller

1. Snap the coupler onto the DIN rail first;
2. Use a tool such as a screwdriver to turn the locking cam until the locking cam engages the DIN rail.

3.3 Remove Controller

1. Use a screwdriver to turn the locking disc cam until the locking cam no longer engages the rail.
2. Pull the release tab to remove the coupler from the assembly

Data or power contacts are electrically disconnected from adjacent I/O modules when the controller is removed.

3.4 Insert I/O Modules

1. When inserting the module, make sure the tabs on the module line up with the grooves of the controller or other I/O module to which it is attached.
2. Press the I/O module into the assembly position until the I/O module snaps into the rail.

After the I/O module is installed, the electrical connection to the controller (or the previous I/O module) and the following I/O module is established via the data contacts and the power jumper contacts.

3.5 Remove I/O Modules
Pull up on the latch to remove the I/O module from the assembly.

When the I/O module is removed, the electrical connection to the data or power jumper contacts is disconnection.

Device Connection

4.1 Wiring
CAGE CLAMP connection is suitable for solid, stranded and fine-stranded conductors.
Only one wire can be connected to each CAGE CLAMP. If there is more than one wire, it must be merged into a point before being connected.

1. Open the CAGE CLAMP by inserting the tool into the opening above the junction.
2. Insert the wire into the corresponding open connection terminal.
3. Once the tool is removed, the CAGE CLAMP closes and the wire is clamped firmly by the spring.

4.2 Power Supply
System and field voltages are supplied by power supply modules. The power supply module of the BL206Pro controller supplies power for the internal electronics of the controller and the I/O modules. If necessary (there are many I/O modules and the current is relatively high), it can also be provided through an independent power supply module.
The fieldbus interface (Ethernet interface), system and field are galvanically isolated from each other.

4.2.1 System Power
BL206Pro controller require 24V DC system power, which is connected from the terminal of the power supply module. The 5V bus voltage required inside the system is converted from the 24V system voltage.
The power supply module only has proper fuse protection, please provide proper overcurrent protection externally.
Please pay attention to matching the output power of the power supply module and the load power to avoid excessive load current.

4.2.2 On-site Power Supply
The power supply module supplies 24 VDC on the field side to power the sensors and actuators.
Field power supply only has proper fuse protection. Without overcurrent protection, electronic equipment can be damaged.

Field-side power is automatically output from the power jumper contact when the I/O module is connected. The continuous load current across the contacts of the power supply must not exceed 10 A.
The problem of excessive load power on the system side or on the field side can be solved by plugging in additional power supply modules. After plugging in an additional power supply module, a new voltage potential may appear on the field side.
In the case where electrical isolation is not required, the field power supply and the system power supply can use the same power supply.

4.2.3 Grounding
When installing the enclosure cabinet, the cabinet must be grounded, and the rail is electrically connected to the cabinet through screws to ensure that the rail is properly grounded. Grounding can increase resistance to electromagnetic interference. Some components in the I/O system have rail contacts that dissipate EMI onto the rail.

5.1.3.2 Ethernet Port
Connect to the Ethernet-based fieldbus through ETH2.
EHT1 is used to connect other nodes that need to be connected to the Ethernet.

5.1.3.3 IP Address Selection Switch
The 8-bit DIP switch is used to set the IP address. The encoding of DIP switches is done bit by bit, starting from DIP switch 1 with the least significant bit (2 0) to DIP switch 8 with the most significant bit (2 7 ), corresponding to decimal values: 0-255.

When the value of the DIP switch is 1111 1111 (decimal 255), the IP address is set according to the web page. The web page setting can specify the IP or set the automatic acquisition. When the web page is not set, the IP address is: 192.168.1.10 When the value of the DIP switch is 0000 0000 – 1111 1110 (decimal 0-254), determine the 3rd byte of the IP address, and the 1st, 2nd and 4th bytes are fixed bytes, namely 192.168.xxx.253
5.1.4 MQTT Identifiers
The MQTT identifier is REG+Modbus mapping address (such as the first DO module first DO: REG1000).
5.1.5 Controller Connection
The BL206 controller comes with 2 x RJ45 Ethernet ports, integrated switch function inside, work in store-and-forward operation mode, each port supports 10/100 Mbit transmission speed and full-duplex and half-duplex transmission mode.
The BL206 controller connect to the router Ethernet network via ETH2 only, while the EHT 1 is for connecting other nodes.
The internal integrated switch supports bypass mode, which can automatically start the bypass mode when the controller system fails, and automatically maintain the link between ETH1 and EHT2.
The wiring of these Ethernet ports conforms to the 100BaseTX specification, which specifies the use of category 5 twisted pair cable as the connecting cable. Cable types S/UTP (Screened unshielded twisted pair) and STP (shielded twisted pair) can be used up to a length of 100m.
