A.Function
2 channel ON-OFF DI and DO transmitting timely. The 2 channel switching condition for 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; and the transmitting equipment is disconnect, while the receiver equipment will disconnect.
B.Feature:
1.2-channel coupler isolated inputs, high reliability and stability.
2.2-channel relay dry contact output, contact current is 30V 1A.
3.collocate wireless data transmission module with 2-3km.
4.Working frequency 433MHz(450 or 470MHz also available)(pls tell us what Frequency you need ? )
5.Data rate : 1200/2400/4800/19200bps (pls tell us what data rate you need ? )
6.RF power: 500mW
7.Receive sensitivity: -123dBm
8.Receive current: 30mA; transmitting current: 300mA
9.Power supply: DC 12V
C. Feature of the output contact as below follows: (the parameters of the relay inside):
