Delock RS-232 Isolator DB9 Female to Male 3 kV – Galvanic Isolation for Serial Interfaces

The Delock RS-232 Isolator provides reliable galvanic isolation between two serial devices. With an isolation voltage of 2500 VRMS (rated 3 kV as per product name), it protects sensitive electronics from voltage spikes and ground loops. The adapter is passive and requires no external power.

  • Galvanic isolation of 2500 VRMS prevents interfering currents between connected devices.
  • 3 kV withstand voltage per product designation for enhanced safety in industrial environments.
  • Compact adapter form: DB9 female to DB9 male for direct connection.
  • Straight connector, not angled – fits standard port layouts.
  • Plug & play, no driver installation required – ready to use immediately.

What sets the Delock Isolator apart

The isolator is designed for environments where ground loops and voltage differences between devices may occur. It preserves signal integrity over longer cable runs. The use of robust components ensures long-term performance.

Ideal for...

This isolator is particularly suitable for technicians, developers, and system administrators who need to operate RS-232 interfaces securely in industrial controls, POS systems, scales, laboratory equipment, or legacy peripherals.

How to use the Delock Isolator

Plug the DB9 male connector of the isolator into the female port of the first device. Then connect the DB9 female connector of the isolator via a standard RS-232 cable to the second device. The isolator is immediately operational, no drivers or configuration needed.
