Cardinal's SB-250 remote display has a 2.6 " (66 mm) high weight display. Message board capabilities are standard with all SB-250s, and feature an array of nine 5 x 7 alphanumeric characters for crisp, clean readouts of upper and lower case letter messages. The high intensity LED is viewable in direct sunlight with a viewing angle of +/- 70 degrees. The weatherproof enclosure meets IP65 requirements and incorporates mounting tabs allowing it to be mounted on a vertical surface.

The interface can autolearn most serial protocols. One custom protocol can be entered into the unit. The interface is configurable for serial data input as either an active or passive 20mA current loop, RS-232 or RS422/485, and also has the connectivity options of fiber optic and ethernet. The SB-250 has annunciators of lb, kg, T, t, G, and N (if output from indicator). The SB-250 employs many of the same features of the SB-500, but in a smaller package.
