Autopowered bright red LED-display 201 needs no external power supply. Current signal 4-20 mA provides the
necessary energy. Therefore, it is possible to install the
meter in places having no auxiliary power available. You
can now replace the autopowered LCD-displays, having
very poor visibility, by bright red LED-displays.
There are two models: basic model 201 without alarms
and model 202 with two alarm contacts.
Display scaling and configuration by front panel buttons.
Unit has digital filter for stabilizing the 4-digit display.
In model 202 You may configure two optional alarms, high
and low. Password is settable for entering configuration
and alarm stages.
