Analogue signal interfaces

The analogue signal interfaces are used for direct connection to a device which produces a continuous variable analogue voltage to indicate the value of the parameter being measured. Usually, the analogue voltage produced by the sensor or a peripheral element is converted into a digital value within the core element to which it is connected. This Standard specifies the electrical characteristics of the analogue signal interfaces. Two types of analogue interfaces are specified:

• Analogue signal monitor interface, ASM
• Temperature sensors monitor interface, TSM
