“Bigger is better” is certainly a rule that can be applied to the Cardinal 210FE’s large display readouts. With a 15-inch W x 9.7-inch H (38-cm W x 24.6-cm H) rugged stainless steel enclosure housing a highly visible 2.24-inch/57 mm high bright-red LED with brightness control, the 210FE is easily viewed from long distance making this indicator ideal for outdoor applications.
