LORDWORLD TTL to RS485 Rail-Mount Converter 600W 3.3V-5V

SKU CH-3PDB-QJNF4

Galvanically isolated rail-mount converter changes TTL signals to RS485 differential output with 600W lightningproof surge protection and 3.3V-5V supply

  • Converts TTL signals to differential RS485 for reliable half-duplex communication
  • Onboard isolated power supply delivers stable voltage without an external source
  • TVS suppressor guards against surge and transient spikes for lightningproof operation
  • Resettable fuse and protection diodes provide over-current and over-voltage protection
  • Compact rail-mount ABS case enables quick DIN-rail installation in tight spaces

Rail-Mount TTL to RS485 Converter

This galvanic isolated module converts TTL signals into differential RS485 for half-duplex communication. It operates across a 3.3 to 5 V logic range and mounts on a standard DIN rail inside an ABS enclosure. Onboard power isolation removes the need for a separate supply at the isolated terminal.

Engineers adding serial links to industrial panels

The converter suits builders who need lightningproof and anti-surge protection on long cable runs. Its resettable fuse and TVS diodes guard against transient spikes and over-current events. Buyers who require full-duplex operation or optical isolation instead of transformer-based isolation must look elsewhere.

600 W surge rating

The 600 W transient voltage suppressor defines the energy the module can absorb during a lightning strike or heavy industrial surge. This single figure decides whether the protection level matches the installation environment.

Questions sur cet article

Should I pick the 3.3V or 5V logic side for my microcontroller?

The module accepts both 3.3V and 5V TTL levels, so you can connect it directly to either voltage without extra level-shifting.

What does the 600W rating mean when the converter is installed in a cabinet?

It specifies the lightningproof and anti-surge energy the onboard TVS and fuse can absorb, not continuous operating power.

Does the RS485 port follow a specific bus standard that limits cable length or node count?

It implements the standard RS485 electrical interface in half-duplex mode; cable length and node limits follow that standard.
