Three-stage DIN Rail Surge Protector HESP4DR www.advantech-bb.com PRODUCT 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 lug • Wide operating Temperature • NEMA TS2 Model HESP4DR protects against lightning strikes, power surges, and other ORDERING INFORMATION MODEL types of voltage disturbances with three stages of protection for each line: INTERFACE LINES PROTECTED MOUNTING NUMBER a gas discharge tube followed by a series resistor and finally a Transient HESP4DR RS-422/485 (5) RS-422/485 DIN Rail Mount Voltage Suppresser (TVS). Five RS-422/485 signals on terminal blocks are supported with a clamping voltage of 6.8 Volts. ACCESSORIES The surge protector is housed in a rugged DIN rail mount case with a CU15B - Copper Grounding Strap protected signal ground connection and dedicated chassis ground lug. In order to work properly, it is important to have a good connection between the #10 grounding screw and a solid earth ground.
