Digital Indicator BDI147

The BASI programmable process indicator BDI147 is designed for wide range of control applications.


The BASI programmable process indicator BDI147 meter with large display (digits 38 mm), with current-voltage or mV input, with 2 or 4 relay (or OC type) outputs and 1 analogue output, according to the customer selection: active current output, passive isolated current output or active voltage output. The meter can be configured with the local keyboard or free -Config software via the RS-485 communication port.
