1 General Specifications 75A Digital Indicating Controller l tiona Func ment nce Enha GS 05P0B40EN n Overview The 75A digital indicating controllers employ an easytoread, 4segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is included as standard. The short depth of the controller helps save instrument panel space. The 75A also support open networks such as Ethernet communication. n Features A 4segment, active (PV display color changing function) color LCD display is employed. Two fivedigit, highresolution displays are possible. Alphabet letters can be displayed in an easytoread manner. The guide display shows parameter names. Easy to operate Navigation keys (SET/ENTER and Up/Down/Left/Right arrow keys) are employed to facilitate making settings. 65 mm depth The small depth enables the mounting in a thin and small instrumented panel. Ladder sequence function is included as standard. This function allows for creating a simple sequence control. Dedicated LL50A Parameter Setting Software (sold separatly) allows for performing programming using a ladder language. Multiline ladder programs such as numerical computation can be simplified using custom ladder instructions. Custom ladder programs allow for secure management using passwords. Various builtin open network functions such as Ethernet are available. Easy connection with various vendors PLCs is possible. Quick setting function Setting only the minimum necessary parameters for operation is possible. (For singleloop control only) Equipped with a multitude of functions Universal I/O, eight control modes (dualloop control, cascade control, etc) and program pattern operation are included as standard. PID control, heating/cooling control, feed forward control, etc. are available. LL50A Parameter Setting Software (sold separately) The parameters and ladder programs of Advanced digital indicating controller can be built from a PC using this software. It makes data management even easier. Dustproof and dripproof IP66 (for front panel) (Not applicable to sidebyside close mounting.)
