YS-102R wireless ON-OFF input and output module is awireless transmission equipment with four 2-channel DI and 2-channel relay DO.
(Ⅰ）Function
2channel ON-OFF DI and DO transmitting timely. The 2 channel switching conditionfor the transmitting equipment can be output timely at the receiver equipment.That is the switching condition for the transmitting equipment is shut down,while the switching condition will be shut down at the receiver equipment; andthe transmitting equipment is disconnect, while the receiver equipment willdisconnect.
The following is the schematic diagram ofthe ON-OFF transmission.

3、 collocatewireless data transmission module with 2-3km.
Working frequency 433MHz(400-470MHz);
RF power: 500mW;
Receive sensitivity: -123dBm
4、 Receivecurrent: 30mA; transmitting current: 300mA

6、 Featureof the output contact as below follows: (the parameters of the relay inside):
(V) Application Example
1,One to one transmitting
1)work modeset Timer or triggered mode, 1 set switch/button can control alert light orengine several miles away.
2)Sendinginput signal can be 1 set dip switch,button or high/low level voltage
3)Receivingoutput signal can drive alert light,moter,engine,electromagnetic valve or PLC.
4)Two YS-102Rcommunicate with each other,its ID and work channel must be the same.
2,Modbus host/slave networking mode
1)slave YS-102Rset acquisition mode,
2)Host is a PCor a touch screen that connects wireless transmission module
3)Host and YS-102Ruse the same Modbus RTU protocol
4)Host musthave the same work channel as YS-102R
The above picture is acquisition modenetworking schematic diagram
(V) OtherApplications of YS-102R
Except ont-to-one transmission and one hostto several slaves control under acquisition mode,YS-102R with other switchtransmission modules(YS-805 and YS-808) can achieve centralized control andcentralized output etc.(those functions must be assigned before purchasing)
The above picture shows 4pcs YS-102Rcontrol 1pc YS-104R
