DeLOCK 62921 cable gender changer RS-232 DB9 Black

This RS-232 isolator by Delock protects all connected devices such as computers, machines, controllers, measuring devices, etc. against electromagnetic and electrostatic discharges as well as surge. Due to the complete galvanic isolation of the connected devices, a continuous data transmission is guaranteed even in the case of earth or ground loops. The isolator can be used as a coupling directly between two DB9 connections without an additional power supply.
