A&D AD-4406-07 Analog Output (4-20mA) (replaces standard RS-232C)

The A&D AD-4406 is the perfect device for converting between different RS232 standards. It can handle voltage levels up to ±15V and has an input range of 4 - 20 milliamps (mA). This means it will work with most devices without any issue, even if they require more power than what this converter provides.
