Features

Both A50 and A51 are RS-232 to RS-422/RS-485 bidirectional converters except that A51 has one more feature: isolation protection, which provides high voltage protection up to 2000V.

All the switches, SW1 and SW2, of A50/A51 are designed to be inside of the converter to protect switch settings from unintended change and introducing communication error without any warning.

The A50/A51 must be powered either from a DC +9V to +30V,
