Product Description

The WattsOn-DISP allows for local display of electrical measurements performed by the WattsOn Power Transducer. Its small size and form factor allow for an easy and clean installation through a panel with the included mounting hardware. Optionally, a NEMA 4X bezel may be provided to allow for installation in harsh environments.

The display parameters are selected by configuring the main WattsOn unit using RS-485 (Modbus). It may be used with WattsOn-1100 units (firmware 4.3 or higher).

The WattsOn transducer configured for use with the display, uses the second pulse output is used for data transmission from the WattsOn. This leaves the RS-485 port free for communication with any other RTU.

The display features a LED backlight allowing viewing in any condition.
