Chapter Product introduction
One、Product overview
MBSL6AD4DI4DOModule is6road0～20mAAnalog input、4Road Digital Quantity Isolated Input、4Digital Quantity Isolated Output(NPNOpen-circuit output of transistor collector)Modular，By isolationRS485Interface output。Modules adopt standardModbus RTUcommunication，It can be directly adapted to various upper computer configuration software.、PLC、DCSetc.。Module power supply、RS485Communication electrical signals are isolated from each other，Effectively suppress all kinds of serial mode and common mode interference，At the same time, it ensures the stability of the module.、Reliable work。
1、UseRS485 MODBUS RTUStandard communication，Configurable Software with Upper Computer、PLC、Industrial touch screen networking、With Communication Status Indicator。
2、Industrial standard：signal control、Power Supply、RS485Electrical signals such as communication are isolated from each other。
3、Lightning Protection for Communication Circuit、Anti-interference design、Polarity Protection of Power Supply。
4、RS485Overvoltage and Overcurrent Double Protection for Communication Signal Output Interface。
5、It can be widely used in signal acquisition and control of industrial field equipment.。
6、Module adoptionSoftware and Hardware Dual Watchdog TimerAutomobile Class Standard，Guarantee that the module never crashes and works steadily and reliably，
7、Output disconnection protection：When appear485Network interruption，When the host does not receive the data sent by the host station within the set time，Modules automatically disconnect the output，Consequently, the safety of field equipment can be automatically protected.。
8、Station address、Communication format can be set by software。
