Adds two isolated RS485/422 serial ports via PCIe with 2500V optoisolation, surge protection and DIN-rail mounting for industrial PLC, CNC and SCADA systems

  • Stable multi-device links via dual-port RS485/422 design
  • System safety reinforced by 2500V optoisolation
  • Reliable operation in harsh sites with built-in surge and lightning protection
  • Flexible wiring and space-saving setup using terminal block and DIN rail mount
  • Broad integration with mainstream PLC, CNC, SCADA and automation brands

Dual RS485/422 serial card

The SMUGDESK PCIe card adds two isolated serial ports to a computer for industrial communication. It uses 2500V optoisolation to protect the host system from electrical interference. Built-in surge and lightning protection helps the card survive harsh environments. A terminal block and DIN rail mounting option simplify wiring and installation.

For industrial automation integrators

This card suits engineers connecting PLC, CNC or SCADA equipment over RS485 or RS422 links. The dual-port design handles multi-device networks without extra adapters. It is not for users who need USB, Ethernet or wireless connectivity. Buyers requiring more than two serial ports should look at something else.

Two isolated ports with 2500V protection

The card comfortably handles standard industrial buses at common baud rates across two channels. Optoisolation and surge circuits give headroom against ground loops and transient spikes. It runs out when a project demands three or more simultaneous serial connections. Additional cards would be required for larger channel counts.

Questions about this item

What slot must my motherboard have for this PCIe dual RS485/422 card?

The card plugs into any standard PCIe slot on the motherboard.

Will the 2500V optoisolation protect older PLCs that lack their own isolation?

Yes, the 2500V optoisolation shields the host and legacy devices from ground loops and transient spikes.

How can I confirm the two RS485/422 ports are communicating after installation?

Use a loopback test or serial monitor software to verify data flow on each port.
