PC interface inputs & outputs



PC interface inputs & outputs to connect on the port COM1 of the PC
Linking by RS 232 line ( max distance 50 meters )
9600 bauds, 8 bits, 1 bit de start, 1 bit stop, no parity, no flow control
An emitter and a receiver make a independent dry contact transmission system by biwired line( 50 meters) without PC


DRY CONTACT TRANSMISSION BY RS232 LINE

Independent working
A set emitter/receiver can work in independent mode
For this they need to be linked by a shielded twisted pair

EMITTER
The inputs are scan each 0,5 seconde.
The inputs contact position are passed by the RS232 to the receiver module

RECEIVER
The interface 8 outputs put in position the outputs relay contact
in fonction of the contact of the interface 8 inputs

The set emitter/receiver is totaly unnoticeable for contact communication
If a contact is closed on the emitter, it is closed to on the receiver


8 lanes receiver
Outputs by relay dry contact

EMITTER
Raw code receiving :
0 8 1 10 13
To signal the inputs 8 tape with " Common " of the inputs

Raw code sending :
0 8 0 10 13
To signal the inputs 8 deconnected

If one of the inputs is connected to " Common " of the inputs the information emission is " 1 "
The emission take place only if one inputs take a state changing.
The emitter and this receiver have a rescue memory. If the power supply is turned of, at the switched on, the inputs and the ouputs are in the state before the blackout.



8 lanes emitter
Dry contact inputs

RECEIVER
Raw code sending :
0 8 1 10 13
To close the relay 8

Raw code sending :
0 8 0 10 13
To open the relay 8

The relay contact are open or close in relation to the" Common " of the inputs
The information " 1 " is equivalent to the closed realy
The receiver have a rescue memory. If the power supply is turned of, at the switched on, the inputs and the ouputs are in the state before the blackout.



 

Exist in 16 inputs and in 40 inputs
Each possibilities are concevale
