The Function of KYL-812
With 4 channel ON-OFF DI and DO, KYL-812 can transmit data timely. The ON-OFF condition of the transmitting equipment can be output timely to the receiver equipment. That is the ON-OFF condition for the transmitting equipment is shut down, while the ON-OFF condition will be shut down at the receiver equipment; and the transmitting equipment is disconnect, while the receiver equipment will disconnect.
