BCD Converter & Input Display


BCD 9708 Binary Coded Decimal Converter

The BCD Converter is designed to convert DC voltage signal into binary signal. Its electronic circuit senses a voltage signal and generates an output signal consisting of two BCD digits, proportional to the voltage measured.

BCD Converter Features

Normally open/closed output function

Typically, the BCD signal features positive voltage values in its application. For instance, the high levels may be +24V while the low levels are 0V. By adding the normally open/closed function that is in inverse to the typical application. In other words, the high levels would be 0V while the low levels would be +24V.

0 to 19 position display

BCD is able to produce display signal from 0 to 19 on the BCD Input Display Unit.

Dual Output Port
The BCD Converter can be used together with the BCD Input Display as one of its output signal display. Another output port can be used as optional port to be connected to SCADA during testing, of to be used by other means deemed fit by the user.


BCD Input Display

2 Digit BCD Input 1/8 DIN Display
