1. General Introduction
Yokogawa AAI835 Analog input output Module is a 4 channels isolated Analog I/O Module can be installed on Field Control Unit or ESB bus node unit for 4 to 20mA Current Input signals from field instrument or valve positioners, also output signals from Field Control Unit to field control devices such as valve positioners, mechanic equipments and etc. HART communication function is optional. Three types of connection selectable as Pressure clamp terminal, MIL connector cable or dedicated cable KS1, Dual-redundant communication is available by installing two communication modules on the same unit. It connects to terminal board AEA4D with signal cable KS1 type.
