Passport I/O Control

The Passport I/O Enviromental Control Unit is a microprocessor based controller, designed for the precise control and monitoring of direct expansion and chilled water boat air conditioning systems from Marine Air. The control is dual voltage, operating at both 115 and 230 Volts, 50/60 Hz. The display is available in both black and white. In chilled water air handlers, the control is referred to as AH-Passport I/O.
The assembly has a ground shield to protect against static interference and RF noise. The circuit board is conformally coated to provide high resistance to external damage or corrosion.

The Passport I/O control meets or exceeds applicable ABYC, U.S. Coast Guard Regulations and CE Directives.
