Compact industrial USB to serial converter with isolation and terminal block connections

Vszerda

Vszerda ADM-2813 USB to RS485/422/232/TTL converter

SKU CH-V7BN-D48GR

Industrial USB converter isolates RS-485/422/232/TTL signals with FT232 chip, lightning and surge protection, 1000 m RS-485 distance and 32-device load

  • Industrial-grade isolation protects equipment from surges
  • FT232 chip ensures stable USB-to-serial conversion
  • Supports RS-485, RS-422, RS-232 and 5V TTL interfaces
  • RS-485/422 reaches 1000 m at 1200 BPS
  • Connect up to 32 devices on a single RS-485 bus

Industrial USB multi-protocol converter

The Vszerda ADM-2813 translates a USB 1.0 or 2.0 port into RS-485, RS-422, RS-232 or 5 V TTL signals. It draws power from the USB bus so no external supply is needed and uses an FT232 chip for the conversion.

Photo-electric isolation with built-in protection

Optical isolation separates the host from the field side while the serial ports include lightning, surge and anti-static safeguards. Automatic data-direction control removes the need for manual flow management and the link works at up to 230.4 kbps on RS-485/422 or 115.2 kbps on RS-232.

For engineers wiring industrial buses

Suits integrators who need a single adapter to talk to 32 RS-485 nodes over 1000 metres at 1200 bps or shorter RS-232 runs up to 10 metres. Not for anyone requiring galvanic isolation on the USB side itself, USB 3.x speeds, or a DB-9 connector without a separate cable.

Questions about this item

What replacement or maintenance will the ADM-2813 need after long-term industrial use?

The unit has no moving parts or user-serviceable components; the FT232 chip and isolated interfaces are solid-state, so no scheduled replacement is required.

Which limit appears first when the ADM-2813 runs continuously at high throughput?

The RS-485/422 bus caps at 230.4 KBPS and 32 connected devices, while RS-232 stops at 115.2 KBPS and 10 metres, so the baud-rate ceiling is reached before distance or node count.

How much noise or heat does the ADM-2813 produce when powered all day on a DIN rail?

It draws power only from the USB-B port, has no fan, and uses photoelectric isolation, so it runs silent with negligible heat rise in a cabinet.
