RTD/mA inputs

Functionality

The RTD and mA analog input module is used for monitoring and metering current (mA),
temperature (°C) and resistance (Ω). Each input can be linearly scaled for various
applications, for example, transformer's tap changer position indication. Each input has
independent limit value supervision and deadband supervision functions, including
warning and alarm signals.
