OneSummary
MB8AI6DI4RO 8The analog signal acquisition module can collect 8 analog signals of 0-20mA, 4-20mA, 0-5V and 0-10V. Each input port signal type can be set by software without jumper. It can collect signals of six trunk or wet nodes (active or passive input); as input of dry contact or sensor (NPN or PNP), it can set jumper common positive or negative input; as active input, it can automatically convert polarity without jumper switch; and four relays can be controlled by MODBUS bus. Modbus-RTU communication can be directly adapted to PLC, DCS and various domestic configuration software.
Signal acquisition, power supply and RS485 communication electrical signals are isolated from each other, effectively suppressing all kinds of serial mode and common mode interference, ensuring the accuracy of data, but also ensuring the reliable work of the module.
Two.Characteristic
1.The Modbus-RTU protocol is adopted.
2.Analog input can set the input signal type of each channel according to its own needs, only need software settings, without jumping line..
ThreeIt integrates 6 trunk connections or wet node signals (active or passive input) and 4 relay outputs.
4.Signal acquisition, power supply, RS485 communication, electrical signals are isolated from each other.
FiveRS485The communication signal output interface adopts over voltage and over current double protection.
SixThe input signal type and communication format can be set by software.
7.Power polarity protection.

Five.Function description of module indicator lamp
1.POW/SET;Module work status indication
A.The green light is always bright: the module works in the running state B. the red light is always bright: the module works in the configuration mode.
2.TXD/RXD:Communication status indication
A.Green light: communication receives data B. red light flashes: module is sending data.
C.The green light is always bright: the communication RS485 line on DATA+ and DATA- is reversed or the connection is broken.
Six.Module right switch function description
1.Operating mode: switch to the top, and then the module power is re-energized; the module works normally in this mode, this mode can not configure the working parameters; the communication parameters of working mode are set by users, default communication parameters of factory (address: 1, baud rate: 9600 bps, check bit: no, stop bit) The 1 digit).
2.Configuration mode: switch to the bottom, and then the module power is re-energized; used to view or set module communication parameters, analog input and analog output parameters, mode communication parameters are fixed (address: 1, baud rate: 9600 bps, check bit: no, stop bit: 1 bit).
