Electrical Properties; Operation And Storage - rotork Modbus IQ Pro Technical Manual

Early assemblies of NIC and Interface Cards were physically joined by their electrical connectors and
a push-fit spacing pillar. Later versions use a threaded pillar, which is useful for higher vibration
environments.

2.2 Electrical Properties

The MFU connects directly to the Interface Card of the actuator. The MFU does not sit in the main
control path for the actuator and does not affect the actuator control integrity.
The Modbus RS-485 fieldbus data highway connections are fully isolated from the actuator
electronics.

2.3 Operation and Storage

The MFU is designed to be stored in the actuator and operated within the same environment as the
actuator. The constraints are:

Operating temperature:

Storage temperature:

Relative Humidity:
-40degC to +70degC
-50degC to +85deg C
5% to 95% (<50degC) non-condensing
