The WBL is every bit as versatile as the SM with an attractive display on a single board. This unit is ideal for those wanting the use of a 20 by 4 character display and to have graphics displayed at the same time. As with our LK units, the GLK12232-25-WBL also gives you the ability to easily use with a 25 key keypad. This product is an idea fit for industrial fax and printer machines. Please note that this product can not be used with the Matrix Orbital Communication & Power Cable.
