Red Lion Controls APLSP4B0 Apollo Slave Display

Red Lion Controls APLSP4B0 Apollo Slave Display is a compact, four‑digit LED panel readout in the Apollo series, designed for panel‑mount installations in industrial control systems. It measures 3.80" long, 1.95" high, and 6.33" deep (96.5 mm x 49.5 mm x 160.8 mm) and uses a 10‑28 VDC supply with a card‑edge termination, enabling clean integration into cluttered control cabinets. The device features red LED digits and is rated IP65 for dust‑tight, water‑resistant performance, with an operating temperature range of 0°C to 50°C, making it suitable for use in typical factory environments. The APLSP4B0 is part of the Apollo family and is marketed as a Slave Display; it carries the base number APLSP and is listed as Obsolete by distributors, indicating it is no longer in production. This four‑digit numeric display provides a clear, high‑contrast readout in a compact form factor, aligning with Red Lion’s legacy Apollo line for panel‑based instrumentation and display applications.
