Digital Input and Output Remote Io Acquisition Module Modbus RTU Communication RS485 Isolated | Бытовая техника

Chapter Product introduction

One、Product overview

MBSL8DI4ROModule is8Road Digital Quantity Isolated Input、4Isolated Output Module of Road Relay，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、Output disconnection protection：When the module slave station detects that the master station has exceeded the set time, it does not send data.，Automatic reset output，Protecting the safety of field equipment。Default uninterrupted network protection function，Options can be set

7、Communication format can be set by software。
