    BUILT-IN ARRESTER An arrester is used to protect a transmitter or receiver from an abnormal voltage such as light- ning surges induced into signal lines. A built-in type arrester is mounted in the terminal unit. A nameplate marked “with arrester” is attached to the terminal unit of transmitter. Installation If surges are likely to appear on the loop 4 - 20 mA, for example because of lightning, it is advis- able to install a built-in arrester should be used in combination with panel mounting type arrester...
