ULI-242T ULI-244TI ULI-244T ULI-246T BB-232HESP BB-HESP4DR 3-Stage RS-232/422/485 Serial Surge Suppressors BB-422HESP BB-485HESP Features • Three stages of protection on every data line: 1) Gas discharge tube 2) Series resistor 3) Transient voltage suppressor • Protected signal ground connection • Rugged terminal block connections • Dedicated chassis ground lugs ULI-244TI ULI-242T BB-HESP4DR BB-232HESP Introduction These three-stage surge suppressors protect against lightning strikes and other voltage disturbances with three stages of protection for each line: a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppresser (TVS). The devices are housed in rugged cases with a protected signal ground connection and dedicated chassis ground lugs. In order to work properly, it is important to have a good connection between the #10 screws and a solid earth ground.
