The increases zone density and makes smaller numbers of loops affordable, yet still holds many of the advantages that a single loop controller might offer.

OS or SI (RKC standard) protocol can be selected. p to units can be interfaced on one RS- or RS-5 communication line. channels Control channels of temperature controls are packed into 9 x 9 x 00mm case. The can reduce your panel cutouts and make your panel board smaller. Heat/Cool Control Host computer The Heat/Cool PI control features heat and cool s for use where process-generated heat exists. This allows the input of overlap or deadband settings which contribute to energy savings. 00% 00% ulti-emory rea p to kinds of combinations of temperature set value, PI constant, alarm set value, etc. for each channel can be registered as "emory area" (recipe). The change of settings caused by the change of a process and product can be simply realized only by switching the "rea". The switching of the area by optional external contact input is also available. The available parameters for multi memory area :, larm set values, PI constants, nti-reset windup, Overlap/dead band, Setting change rate limiter, Channel used/unused rea P, I,, etc.. areas Select rea P, I,, etc..
