ABB 3BSE005831R1 Touch screen control board touch screen

Communication parameters: Communication is carried out through polling, that is, the master station sends requests to the slave station and receives responses. Both COM1 and COM2 ports can work simultaneously as Modbus interfaces, and the Modbus working mode of the interfaces can be set through the engineering tool. The topological structure supports RS232 point-to-point and RS485 multi-point. In RS232 mode, there is only one master station and one slave station, and in RS485 mode, one master station and up to 31 slave stations are allowed. The maximum cable length is 15 meters in RS232 mode and 1.2 kilometers in RS485 mode. A variety of transmission media are supported, among which the commonly used one is the shielded twisted pair with a terminal resistor that conforms to the RS485 bus specification.

Other parameters: The operating voltage is 24Vdc/120Vac, and the net weight of the product is approximately 0.9kg.
