W&T Model 66201 - RS422/RS485 Isolator, Industry

Model: 66201

$165.00

Serial Isolator for the control cabinet

The Isolator model 66201 enables galvanically isolated connection between RS422 devices and RS485 bus systems.

Interfaces:

  • 2x RS422/RS485
    • 9-pin Sub-D connector
  • Galvanic isolation between the ports
    • Isolation voltage 1kV DC

Management and Connectivity:

  • Automatic control in RS485 operation
  • No re-configuration of transmission parameters required
  • High transmission speeds of up to 3 Mbaud

Power supply:

  • External
    • 12V-24V AC/DC via plug-in screw terminal
    • Galvanically isolated power connection
  • Do you need overvoltage protection? - See Isolator 66203

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

 

Problem of compensating currents:
Control loops are often potential-free. But if the controllers are connected to ground through the control bus and PC, compensation currents can unbalance the entire control loop. In such cases you need to ensure that the bus is only connected to the PC galvanically isolated or that the PC is made potential-free by suitable means.
