Serial Converter Repeater Isolator DeLOCK 64314 RS-232 Black 33x63x17mm

The DeLOCK 64314 RS-232 serial converter, repeater and isolator provides galvanic isolation for RS-232 connections, protecting connected equipment such as computers, machines, controllers and measuring instruments from electromagnetic and electrostatic discharges and surge. Housed in a compact black plastic enclosure (33 × 63 × 17 mm), the device allows continuous data transmission even in the presence of earth or ground loops and can be connected directly between two DB9 ports without an external power supply.

Advantages

The isolator implements full galvanic isolation to prevent ground loop issues and reduce noise and transient interference on RS-232 lines. Its compact plastic housing makes it suitable for installation in confined spaces, and the plug‑in DB9 design simplifies integration between existing serial devices. No additional power supply is required for operation.

Suitable for

• Protecting PCs, controllers and industrial machines with RS-232 interfaces
• Connecting measuring instruments and data loggers over RS-232
• Extending RS-232 links in environments with potential ground loops or electrical interference

How to use

Plug the isolator directly between two DB9 RS-232 connectors so that one side connects to the host device and the other side to the peripheral. Ensure connectors are firmly seated and that signal pins match the existing cabling. The device operates without an external power source; once connected, it provides isolated pass‑through for RS-232 signals and maintains data transmission even when ground potentials differ.

Recommendations

Use the isolator in installations where RS-232 lines are exposed to electrical noise, potential surges, or different ground potentials. Verify pinouts before connection and avoid placing the unit near strong EMI sources for optimal performance.
