This Delock RS-232 isolator protects all connected devices, such as computers, machines, controllers, measuring devices, etc. Against electromagnetic and electrostatic discharges and overvoltage. Thanks to the complete galvanic isolation of the connected devices, continuous data transmission can be ensured even in the case of ground or ground loops. The isolator can be connected directly between two DB9 connections without an additional power supply.
