## Summary description

DELOCK model 63003 is an Ethernet converter that translates RJ45 network signals to RS-485/RS-422 via a terminal block interface and includes surge protection. It enables integration of serial industrial devices into Ethernet networks, supporting differential serial communication for long-distance, multi-drop or point-to-point connections. Suitable for connecting PLCs, sensors, controllers and legacy serial equipment to modern network infrastructures.

## Long description

DELOCK Ethernet converter RJ45 to RS-485/RS-422 with terminal block and surge protection (model 63003) converts Ethernet RJ45 signaling to differential serial interfaces RS-485 and RS-422 through a screw terminal block. The device is designed to allow integration of serial industrial equipment into Ethernet networks, enabling long-distance and multi-drop serial communication while providing built-in surge protection to reduce risk from transient voltage events. It is intended for installations where legacy PLCs, sensors, motor controllers or other serial devices must be accessed or monitored over a network.
Advantages
The converter supports both RS-485 and RS-422 differential communication, simplifying connection to a wide range of serial devices using a terminal block interface. Integrated surge protection helps protect connected equipment from electrical transients on the serial lines. Its RJ45 network interface provides straightforward integration into existing Ethernet infrastructures without requiring complex cabling or protocol changes. The compact design and clear wiring points reduce installation time and make it suitable for control cabinets and industrial enclosures.
Suitable for
 Connecting PLCs and industrial controllers to Ethernet-based monitoring or SCADA systems
 Linking sensors and actuators with RS-485/RS-422 interfaces into a local network
 Extending serial links over longer distances or multi-drop topologies
 Integrating legacy serial devices into modern IT/OT environments
When it may not be suitable
This converter is intended for converting physical interfaces between RJ45 and RS-485/RS-422 and providing surge protection on the serial side; it does not replace protocol converters or gateways that translate application-layer protocols without additional configuration. It may not be suitable when native Ethernet-enabled devices (with built-in TCP/IP stacks) are required, or when advanced protocol translation, buffering, or device management features are necessary beyond physical-layer conversion.
Key specifications
 Interface: RJ45 (Ethernet) to RS-485 / RS-422 (terminal block)
 Serial communication: Differential RS-485 and RS-422 signaling
 Protection: Built-in surge protection on serial lines
 Mounting: Compact unit suitable for control cabinets and DIN-rail environments (refer to mechanical details from manufacturer)
 Use case: Multi-drop and point-to-point serial topologies over extended distances
How to use
Physically connect the Ethernet RJ45 port to the network switch or router and wire the RS-485/RS-422 differential pairs to the screw terminal block following the device wiring diagram and polarity markings. Configure connected equipment to use the appropriate serial parameters (baud rate, parity, stop bits) and select RS-485 or RS-422 mode as required by the remote device. Verify grounding and common reference connections in industrial environments to reduce noise and ensure reliable communication. Test communication with a known-good serial device or diagnostic tool before deploying into production.
What to consider before purchase
 Ensure target devices use RS-485 or RS-422 physical layers and confirm required wiring/polarity
 Verify needed serial parameters (baud rate, parity, stop bits) and any protocol requirements
 Confirm space and mounting method in your control cabinet or enclosure
 Check environmental and electrical specifications for your installation (temperature, transient conditions)
Usage recommendations
For reliable operation, maintain proper cable shielding and grounding, use twisted-pair cabling for differential signals, keep cable lengths within recommended limits for RS-485/RS-422, and document wiring and configuration settings. When possible, perform an initial bench test of serial communication before full deployment and ensure surge protection complements system-wide protection measures.
