 Overview
The GX90UT is a PID control module that connects to
the GX/GP, expandable I/O units, and GM main units
and sub units.
● TheGX90UTPIDControlModulecanperform
PIDcontrolonuptotwoloops.Itisequippedwith
twocontrolinputs,twocontroloutputs,eightdigital
inputs,andeightdigitaloutputs.Inadditiontosingle
loopcontrol,cascadecontrolandloopcontrolwith
PVswitchingarepossible.Forthecontroloutput,
youcanselectcurrentoutputorvoltagepulsefor
eachloop.
● InstallingthePIDControlModuleintheGX/GP/GM
enablesPIDcontrolofupto20loops/system(upto
6loops/systemfortheGX10/GP10/GX20-1/GP20-1/
GM10-1). In addition to control loop monitoring and
thecontrolgroupscreenforconvenientoperation,
adjustmentusingthetuningscreenisavailable.
● Addingthe/PGoptiontotheGX/GP/GMmainunit
allows 99 patterns and 99 segments (1 pattern)
ofprogrampatternstobestoredinthemainunit.
Further,upto32timeeventsand32PVeventscan
besetforeachsegment.
● TheGX90UTcontroldatacanbeacquiredand
recordedintheGX/GP/GMmainunit.
