When the SEND terminal controls the inductive load (such as a relay), a counter-electromotive force can cause the transceiver's
malfunction or damage. To prevent this, we recommend adding a switching diode, such as an "1SS133," on the load side of the
circuit to the counter-electromotive force absorption. When the diode is added, a switching delay of the relay may occur. Be sure
to check its switching action before operation.
