The CUB4 offers a large display in a miniature package with a choice of three displays; reflective, red backlight or green backlight. The backlight versions require power from an external 9-28 VDC supply. The optional power supply (MLPS) is designed to be attached directly to the rear of the CUB4 and is powered from an 85-250 VAC source. The CUB4 series has a lightweight, high impact plastic case with a clear viewing window. The sealed front panel with the silicone rubber reset button meets NEMA 4X/IP65 specifications for wash-down and/or dusty environments, when properly installed.
