DeLOCK 64265 Serial Converter Repeater Isolator RS-232 RS-422/485 Black

The DeLOCK 64265 is a serial converter, repeater and isolator that enables data transmission between devices with RS-232 and RS-422/485 interfaces. Housed in a robust metal enclosure, the unit is compact (50 × 84.6 × 23 mm) and designed for use in industrial environments and fieldbus systems, providing galvanic isolation and protection against electrostatic discharge.

Advantages

The converter supports RS-232 and RS-422/485 protocols in one device, offers switchable internal terminating resistors via pin headers and includes repeater functionality to extend communication range when two units are linked. The metal housing provides mechanical protection, EMI shielding and multiple mounting options for installation in control cabinets or on DIN rails.

Suitable for

• Connecting RS-232 equipment to RS-422/485 networks
• Fieldbus and industrial automation installations
• Extending RS-232 link distance using two connected converters
• Environments requiring galvanic isolation and ESD protection

How to use

Install the converter in a suitable location using the available mounting options and connect the RS-232 device to the RS-232 port and the RS-422/485 network to the corresponding terminal. Configure the internal terminating resistors with the onboard pin headers according to the network topology and impedance requirements. For extended RS-232 distance, connect two DeLOCK 64265 units directly and verify signal integrity and grounding before commissioning.

Recommendations

For reliable long-distance communication, enable terminating resistors only at the ends of the bus and ensure consistent wiring and grounding practices. Use the metal housing mounting options to minimize mechanical stress and place the converter away from strong electromagnetic sources.
