I.Function

  4channel ON-OFF DI and DO transmitting timely. The 4 channel ON-OFF conditionfor the transmitting equipment can be output timely at the receiver equipment.That is the ON-OFF condition for the transmitting equipment is shut down, whilethe ON-OFF condition will be shut down at the receiver equipment; and thetransmitting equipment is disconnect, while the receiver equipment willdisconnect.

The following is the schematic diagram ofthe ON-OFF transmission.
