The relay module is a module used to connect two different devices, usually using DC24V power supply, KJ2221X1-BA1 bus signal input and output electrical isolation, can enhance the anti-interference ability of the whole system, and has the function of expanding the detector bus communication distance.

The relay module is mainly used in the area where the bus is in a relatively strong electromagnetic interference and the bus length exceeds 1000m and the bus communication distance needs to be extended. The main technical indicators include static working current ≤20mA, load capacity and compatibility can be configured with 1 ~ 242 point bus equipment, compatible with all bus equipment, isolation voltage between bus input and bus output voltage ≥1500V, the use of ambient temperature -10℃ ~ +50℃, relative humidity ≤95%, no condensation, The overall dimensions are 85mm×128mm×56mm.

In addition, there are many brands that offer WIFI relay solutions, such as MT7628 modules and B-LINK modules. These trunk modules usually include a variety of different types and specifications, and can be selected and configured according to actual requirements.

The repeater module is a network device that the KJ2221X1-BA1 is used to extend the range of a local area network (LAN) at the physical layer. Its main function is to receive, amplify and re-transmit network signals, thereby extending the transmission distance of signals.

Repeater modules are typically used to enhance signal strength and ensure reliable data transmission when the cable length exceeds the maximum allowed distance. KJ2221X1-BA1 plays a role in extending the signal range and connecting different network segments in the network.

The repeater module works by receiving a signal from one network device, such as a switch, router, or other network node, amplifies and processes it, and then sends it to another network device. The KJ2221X1-BA1 does not involve parsing or processing of data, but simply amplifies and forwards signals.

It should be noted that the repeater module cannot be used to connect different types of networks (such as Ethernet and wireless networks), nor can it increase the bandwidth of the network or improve the performance of the network. It is mainly used to extend the physical range of the LAN, so that the signal can be transmitted over longer distances.
