RTU communication interface and 24V/100mA supply output for free use. The meter can be
ordered in two power supply versions.
The device has 4 buttons being used for main presets programming. To get high
protection level, the keyboard is mounted under transparent cover. To allow user to change
presets without opening the cover, an IR sensor is mounted. Remote controller keyboard is
