Isolation (nur A53):

• 2 kV

MTBF:

• 1.870.854 Stunden (Telcordia/GB)

Garantie:

• 5 Jahre (www.moxa.com/warranty)

The A52 and A53 are general-purpose RS-232 to RS-422/485 converters, ideal for users needing to extend RS-232 communication distance and enhance serial networking capabilities. Supporting RS-232, RS-422, and RS-485 (both 2-wire and 4-wire), both models include automatic data direction control (ADDC) for RS-485 and flow control via RTS/CTS.

The A53 model stands out with integrated 2 kV isolation, offering added protection in electrically noisy environments. Their compact size and desktop mounting design make both converters easy to integrate into industrial, lab, or embedded systems.
