OUTLINE
EC5300R Digital Indicating Controller has a large-sized display excellent in visibility.
Since it is a light guide system, it is clear also outdoors. And dial setting is fulfilled easy operation. In addition, self-tuning is equipped standard. PID, gapped PID, heat/cool control or servo PID are available as control functions. As described above, the EC5300R 1/8DIN controller is applicable to a broad use.
