System Components

2.1  Introduction 

This section gives an overview of the components used in the DeviceNet system. The field unit is 
installed in each MX actuator. The network cable connects the field unit to the network via the actuator 
terminal block. The network cable is connected to a host controller, typically a PLC. 

2.2  Hardware 

NOTE:

 Recommended storage procedures are detailed in Bulletin LMAIM1314 Limitorque MX 

Maintenance and Spare Parts Manual. Failure to comply with recommended procedures will void the 
warranty. For longer-term storage, contact Limitorque for procedures and recommendations.

2.2.1  Limitorque MX 

The MX is a multi-turn valve actuator designed for operation of ON-OFF and modulating valve applica-
tions. This actuator controls the opening and closing of valves. See Figure 2.1.
