Integral type field control units mounted within a Rotork actuator electrical housing such
as the IQ, IQT or Q range actuator.
Externally mounted field control unit. Various packages are available, including 'Pakbox',
weather-proof box, or rack mounting. The unit may be used for either actuator control
applications, or for general purpose applications such as pumps, blenders etc. Its
complement of I/O is 8 digital inputs, 4 changeover relay outputs, 2 analogue inputs and
1 analogue output.
4.2 Control and Indication
The field units each report information to the master station that can be viewed on the integral LCD
display, or collected from the serial communication port of the master station for use on another
display system. The reported data is already organised and requires no configuration by the user;
each field unit automatically reports all its available data.
Commands to operate the output devices may be sent over the system, the initiation of the command
can either be from the integral keypad (under the correct access code) or from the serial or Ethernet
data link. Once again the organisation of these commands is already configured and the user only has
to address the correct register to implement the command.
