LORDWORLD RS232 to RS485 Isolated Rail-Mount Converter (B)

SKU CH-A8CQ-KHY9Z

Converts RS232 to RS485 with digital and power isolation, 300–115200 bps, TVS surge protection and a switchable 120 Ω terminator in a rail-mount case powered from 6–36 V DC

  • Converts RS232 to balanced RS485 at up to 115200bps
  • Isolated power and signal paths need no extra supply
  • TVS protection handles 600W lightning and surge events
  • Selectable 120R termination via onboard switch for bus matching
  • 6V to 36V DC input fits industrial rail-mount installations

Industrial RS232 to RS485 Converter

The LORDWORLD isolated rail-mount converter translates RS232 signals into balanced differential RS485 for industrial, agricultural and IoT networks. It supports stable transmission from 300 to 115200bps and integrates both power-supply and digital isolation on a single module. No external isolated supply is required, keeping cabinet wiring simple. The unit mounts on a standard DIN rail inside an ABS enclosure.

Installation checks before ordering

Verify that your host device provides a genuine RS232 port with the correct pin assignment for the converter’s DB9 or screw-terminal side. Confirm the available DC source falls within the 6V to 36V wide-range input and can deliver enough current for the isolated rail. Check whether the RS485 bus already uses a 120R termination resistor; the onboard switch lets you enable or disable the integrated resistor to match the bus topology. Ensure the cabinet has DIN rail space for the module’s footprint.

Suits noise-prone field deployments

Engineers building long-distance sensor buses, PLC links or remote telemetry nodes will benefit from the onboard TVS surge suppression, resettable fuse and 600W lightningproof rating. The isolated design rejects ground loops common in factory and outdoor installations. Buyers who need USB, Ethernet or wireless interfaces, or who require protocol conversion beyond transparent RS232-to-RS485 translation, should look at a different class of gateway.

Pytania dotyczące tego produktu

What comes in the box and do I need a separate power supply?

The converter includes the rail-mount unit with screw terminals for RS232, RS485 and 6V–36V DC input. Onboard power-supply isolation means no extra isolated supply is required for the RS485 side.

How do I decide whether to enable the 120R termination resistor?

A slide switch on the board activates the 120R resistor across the RS485 output. Enable it when this device sits at the end of a long bus; leave it off for mid-bus or multi-drop nodes.

What does the 300–115200bps range mean for a real installation?

The link auto-negotiates any standard baud rate between 300 and 115200bps, so it handles everything from slow telemetry to fast PLC polling without reconfiguration.
