The Bel modules provide internal filter networks on the transmit channels, in addition to both transmit and receive high voltage isolation transformers, plus common mode chokes on both channels for EMI and noise suppression. • Suppression of board induced noise can be achieved with precision layout instructions, along with careful consideration of the selection and placement of discrete components for the interface circuit.
