58015: 4-Port RS-422/485 3kV Isolated PCI Express Card

Product Overview: Industrial Reliability for Critical Environments

Shentek introduces the 58015, a high-performance 4-port Serial RS-422/485 PCI Express card designed specifically for robust industrial and medical applications. Built on the PCI Express 1.1 base specification, this card provides a seamless expansion of high-speed serial communication while ensuring maximum hardware protection through advanced galvanic isolation.

Robust 3kV Isolation and 15kV ESD Protection

In demanding environments like MRI suites or factory automation, ground loops and electrical surges can destroy sensitive host systems. The 58015 features 3kV Isolation Protection to block common-mode noise and 15kV ESD protection to shield all signal lines against electrostatic discharge.
