JaRa 2115B RS232/485 to four-port RS485 splitter |
|
2115B is a 4-port RS485 splitter designed for industrial applications and supports the expansion of one RS232/485 to four RS485 interfaces. It is used to complete the distribution of the 485 bus to expand the communication capacity of the 485 line and extend the communication distance. It is more convenient to set up a 485 network. This product adopts Jierui industrial modular design and supports installation methods such as rail-mounted and wall-mounted installation. In addition, the product adopts photoelectric isolation to transmit signals, which can effectively protect your equipment and network, and the 9~24V variable voltage power supply is more convenient to use. |
| ◆The interface is compatible with EIA/TIA RS232C and RS485 standards. ◆The communication method is half-duplex. ◆It is divided into the master terminal and the controlled terminal. The master terminal provides RS232 and RS485 interfaces. The controlled terminal has 4 RS485 interfaces ◆Main Data communication can be carried out between the controlled and controlled ends, and data communication cannot be carried out between the 4 485 ports of the controlled end. ◆The main control end and the controlled end are optically isolated to effectively protect the main equipment. The power supply is connected by the main control end. The column is connected to an external power supply, and the main control end is isolated from the controlled end. The communication status and power status are indicated by 3 LED tubes, which are respectively sending, receiving, and power indication. The distributor can be connected in cascade mode | | | | | | |
| ◆Communication mode half-duplex ◆Interface format, the main and controlled terminals are all 10-hole binding posts ◆Transmission distance 1200m ◆Maximum speed 300~115200bps ◆Support 32 standard load equipment ◆Failure protection no ◆Power supply external 9~24 DC power supply ◆Power isolation transient 7000V voltage isolation ◆Power <0.8W ◆Flow control mode automatic flow control ◆Optical isolation 2500V continuous voltage isolation ◆Communication delay <2ms ◆Using temperature -20℃~+70℃ ◆Using humidity 5%~95 % | | | | | | |
