Red Lion Controls APLSP4AO 1001 Display Module

The APLSP4AO Apollo Slave Display from Red Lion Controls is a 4‑digit red LED module that displays numeric values issued by Apollo host equipment via the Apollo BCD interface. It accepts full parallel or strobed BCD input with DIP‑switch selectable decimal points and configurable 0 or 1 true logic for both Data and Strobe signals; digits 0–9 are supported, and individual digits can be blanked by a BCD value greater than 9. This 4‑digit variant uses an edge‑card interface and is built for indoor use with an IP65 front panel (NEMA 4/IP65 front) and UL 50 Type 4 enclosure rating for the front. Optional accessory boards are available to cascade multiple displays in a sequence. Powering the 5 V version, it draws up to 200 mA; the unit measures 3.80 in (96.5 mm) long, 1.95 in (49.5 mm) high, and 6.33 in (160.8 mm) deep, making it suitable for compact control panels where a clear numeric readout is needed.
