6.3.2 Overvoltage Surge Protection

Remote connections to current transmitters can sometimes be subjected to voltage surges. Best practice is to limit the maximum surge voltage applied to the XTR117 to as low as practical. Various Zener diode and surge clamping diodes are specially designed for this purpose. Select a clamp diode with as low a voltage rating as possible for best protection. The absolute maximum power-supply rating on the XTR117 is specified at 40 V. Keep overvoltages and transients less than 40 V to maintain reliable operation when the supply returns to normal (7.5 V to 36 V).

Most surge protection Zener diodes have a diode characteristic in the forward direction that conducts excessive current, possibly damaging receiving-side circuitry if the loop connections are reversed. If a surge-protection diode is used, use a series diode or diode bridge for protection against reversed connections.
