PSE-811 LT45A/47A Series Compact Bodies Easy-to-read display On the display, measuring value (PV) is indicated in green and setting value (SP) is indicated in orange LEDs. Frequently used operation can be assigned to the FUNC key 96mm 96mm By assigning frequently used operation such as Auto/Manual and RUN/READY to the FUNC key, only one press of a button enables switching the functions. 65mm 48mm 96mm There are size 48x96mm and 96x96mm available. Depth is only 65mm, so it is space saving for any installation Advanced controllability 65mm Overshoot suppression factor Small (SP) (SP) PV PV Overshoot suppression factor Large High-performance PID PID Time Time In addition to the conventional PID, “High-performance PID” is available which has unique algorithm aim to converge hunting quickly to decrease settling time. By “Overshoot suppression function” which controls overshoot at SP changing and/or disturbance response, the control has been able to develop stronger resistance for disturbance and superior stability. Three types of Auto tuning Step control Along with the standard algorithm, auto tuning for a target which has relatively good responsiveness and for a target which has good heatretention are provided to perform appropriate control easily. Preset maximum 8 setting values and each step can reserve hold time and ramp setting. This function delivers maximum 8 steps program control Zone PID control STEP1 STEP2 STEP3 STEP4 When PID parameter change is necessary depending on the temperature range such a case as furnace temperature control, preregistered 8 groups of PID parameters are assigned to every set temperature ranges (max. 8 zones) and perform operation by automatically changing the parameter depending on the measuring value (or setting value).

However, it requires dedicated loader cable (sold separately). Internal event can be output as external digital (contact) output by logical operation. Loader software (sold separately) On LT45A/47A… Event 1 Event 2 Event 3 Program Operation 3 points of event can be output Result of the logical operation which performed on selected five points of various internal events is able to be assigned to the three points of external digital outputs. It can simplify process of event outputs which logical operation was conventionally performed on receiver side. Various parameter settings and data acquisition are available by connecting this controller to the PC which the loader software is installed. 2 ■ SPECIFICATIONS Power consumption: DC power supply:
