The G90 Series is a large display electronic counter with an LED digit size of 56.8 x 32.4mm.
The G90 Series is available in 6 digits and it can be directly hooked to an input signal source of up to 1kHz count speed.
Mode of counting are Add/Subtract and Quadrature.
Reset is done remotely.
It has a built-in memory for count value retention in case power is lost.
Power source is AC100 – 240V and an external power supply of DC12V is available for the sensors.
Additional features include Decimal Point position, Free Write, and input inhibition.
The G90 Series has a very sturdy and heavy duty casing which can be hanged, base- or wall-mounted.
