This 4-way ON-OFF module is to transmit the ON-OFFcondition to a remote place wirelessly in time. When here the switch conditionis ON, the output in the remote place is ON. When the local switch condition isOFF, the other terminal is OFF.

Features:

1. 4-way isolated input, high reliability andstability.

2. 4-way relay dry contact output, contact current is220V, 5A.

3.Collocated with a wireless data module inside whosetransmitting distance is about 2km-3km;

4.the working frequency 433MHz (450 or 470MHz alsoavailable ); (pls tell us what frequency you need ? )

5.RF power: 1000mW;

6.Receiving sensitivity: -120dBm

7. Receiving current: 60mA; transmitting current:350mA

8. Power supply: DC 12V-30V

9.data rate : 1200pbs/2400bps/9600bps/19200bps (pls tellus what data rate you need ? )

10. Dimension: 95mm x 90mm x 40mm

11.YS-105R can communicate with YS-101R,YS-104R,YS-108R,andalso can work with data modems YS-C20 Series as a combination to meet users'special uses.

II. Applications of YS-105R

Except ont-to-one transmission and one hostto several slaves control under acquisition mode,YS-104R with other switchtransmission modules(YS-105R and YS-108R) can achieve centralized control andcentralized output etc.(those functions must be assigned before purchasing)
