LORDWORLD Industrial Isolated USB RS232 RS485 TTL Converter development board

SKU CH-715B-WEDA0

Industrial isolated converter links USB, RS232, RS485 and TTL buses with FT232RL, onboard power and digital isolation, TVS surge suppression, resettable fuse, selectable 3.3V or 5V TTL levels.

  • Industrial-grade isolation protects equipment from surges and spikes
  • FT232RL chip ensures reliable USB-to-serial communication
  • Switchable 3.3V or 5V TTL levels match diverse devices
  • TVS diodes and resettable fuse guard against over-voltage and over-current
  • Aluminium alloy enclosure delivers durable shielding in harsh environments

Industrial USB multi-bus converter

The LORDWORLD development board converts between USB, RS232, RS485 and TTL interfaces in both directions. It is built for engineers and integrators who need reliable serial links in industrial or automation environments.

Isolation and protection features

Onboard unibody power-supply and digital isolation remove the need for an external isolated supply while keeping signals jamproof. TVS diodes, a resettable fuse and protection diodes suppress surges and transient spikes, and a 3.3V or 5V switch sets the TTL level for the Group B terminal.

Interface practical limits

The aluminium enclosure houses all protection circuits, but the supplier notes there is no protection between the two power supplies of the host terminal. Users must plan their wiring accordingly when connecting equipment across the isolation barrier.

Questions sur cet article

Will the resettable fuse and protection diodes on this LORDWORLD converter need periodic replacement?

The onboard resettable fuse and protection diodes are designed to self-reset after over-current or over-voltage events, so no scheduled replacement is required under normal operation.

What is the first limit reached when running the isolated RS232 RS485 TTL links continuously at high baud rates?

Sustained high-speed traffic is constrained by the FT232RL USB interface bandwidth and the digital isolation channel throughput, which set the practical ceiling for continuous data rates.

How much heat and noise does the aluminium-alloy enclosed board produce when powered all day?

The unibody power-supply and digital isolation run at low power consumption, and the solid aluminium alloy enclosure passively dissipates heat without any fan, so operation is silent and stays warm rather than hot.
