Main features

Up to four (4) set values can be registered

Up to four (4) set values can be registered / switched. Set value can be also switched by digital input.

Abundant Inputs/Outputs

Varieties of combinations of various optional inputs/outputs
※The number of digital outputs depends on the model and the specifications.
※Analog output may not be available depending on the control type and the model.
※For RB100, either communication function or digital input must be selected.

Response speed can be changed

Response speed can be easily changed against the controllability obtained by Autotuning. nYour desired response can be selected from 6 stages.

Loader communication as standard

All models now have a loader communication port.

Configuration data management software (PROTEM2) is available
