OX-6842, OX-6802, and OX-6844 are 8-channel remote IO controllers launched by Shenzhen Ouxintong Information Technology Co., Ltd. after OX-6042. The number of channels it controls has expanded from 4 in 6042 to 8, including 8 DI, 8 DO, and 8 AI inputs. DI supports both dry and wet nodes, with optocoupler isolation; DO is a relay output with control capability of 5A 250VAC or 5A 30VDC; The first 4 channels in AI input support 0-5V voltage input, while the last 4 channels support 4-20mA current input with an accuracy of 10 bits. OX-6842, OX-6802, and OX-6844 respectively support three forms of communication: Ethernet, RS485, and Wifi.
OX-6842: This is an IO controller that uses Ethernet for control. The commonly used communication protocol is Modbus TCP protocol, and the conversion protocol for the module is selected as Modbus TCP to RTU. DI, DO, and AI correspond to different registers. If you want to control through Modbus RTU protocol, it is also possible. At this time, set the conversion protocol of the module to "none" and send Modbus RTU protocol through TCP for control. This product can conveniently and reliably collect switch values, control relays, and collect sensors through Ethernet.
OX-6802This is a usageRS485Controlled by busIOcontroller. andOX-6842Compared to that, it only supportsModbus RTUProtocol, but it has low cost and is suitable for use throughRS485Bus is used to control relays, collect switch and analog signals. The default baud rate is9600bpsThe baud rate can also be set.
OX-6844：6844and6842Compared to increaseWIFIInterface, this can save the trouble of network cable connection. It also has an Ethernet interface.WIFICan be used asAPIt can also be used asSTAConnect the router in a certain way.
OX-6844N: Compared to 6844, this product has added P2P functionality. That is to say, with the help of Ouxintong's P2P technology, remote relay control, switch quantity collection, and analog quantity collection can be achieved anywhere through OXVircom or mobile P2P software.
