SPECIFICATIONS
Description
Featuring 4
1/2 digits of rate and 8 digits of total, the IT 300N is a
battery powered indicator capable of accepting magnetic
pickup, DC pulse and switch closure inputs. The unit provides a
loop powered 4-20mA output. The IT 300N uses the 4-20mA
loop to provide power when this output is used.
