When the SEND terminal controls the inductive load (such as a relay), a counter-electromotive force can cause
* 1
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.
VSEND is used for the 144 MHz and 430 MHz bands, and HSEND is used for the HF, 50/70 MHz bands by default.
