A.Summary
MB10DI8RO 10Switch input acquisition and 8 relay output module can collect 10 dry or wet signal contact node (active or passive input), can input common anode or common cathode, and automatically switch the polarity, no jumper switch. 10 way switch quantity signal collected data through the RS485 interface output; 8 way relay can be controlled via the MODBUS bus; control interface for the isolation of RS485, using Modbus-RTU communication, direct fit PLC, DCS and domestic various configuration software.
Open signal acquisition, relay output, power supply, RS485 communication electrical signals isolated from each other, the effective suppression of all types of serial mode and common mode interference, but also to ensure that the module works reliably.
Two.Characteristic
1.Using Modbus-RTU protocol.
2.Signal acquisition, relay output, power supply, RS485 communication electrical signals isolated from each other.
ThreeRS485The communication signal output interface is protected by the overvoltage and overcurrent.
4.Input signal type and communication format can be set by software.
FivePower polarity protection.
6.Open signal setting
1)When set to the active input, input signal can also be used as input for a total of yin and yang or input, do not need to set the jumper, the internal polarity reversal function.
2)When set to dry contact input, as long as the short signal to the signal to the public side of the signal. However, users need to specify when buying, open into a common or isolated (isolated from the price higher).

Six.Module indicator lamp and switch function specification
1.POW/SET;Module working status indication
A.Green light: the module works in the running state. B. red light: the module is configured to write parameters, need to re power up.
2.TXD/RXD:Communication status indication
A.The green light flashes: the communication receives the data B. red light flashes: the module is sending data
C.The green light is always on: DATA+ and DATA- on the communication line RS485 line is connected to the reverse or the connection is broken.
3.Module right reset switch
1)When the communication parameters (module address, baud rate, parity bit) do not know or communication parameter misspecification, and can not establish contact module communication, the solution is to reset the communication parameters; we use the clip to hold the reset switch is not open, 5 seconds after the [POW/SET] module of the red indicator lights, release the reset switch, the communication the parameters have been reset, as long as the power supply module after the restart time, the communication parameters of the module has been reset.
2)Communication parameters after reset: Address: 1, baud rate: 9600bps, parity: No.
