1 Analog I/O Option OPCAIO
1.1 Introduction
1.1.1 OPCAIO Analog I/O Option Module
The Analog I/O card is supposed to be used in the following cases:
• Providing battery back-up of clock function on control card
• As general extension of analog I/O selection available on control card
• Turning frequency converter into de-central I/O block supporting Building Management System with inputs for sensors and outputs for operating
dampers and valve actuators
• Support Extended PID controllers with I/Os for set point inputs, transmitter/sensor inputs and outputs for actuators.
