Moving Message Displays
We produce a modular Moving Message display system. Each module consists of an intelligent 6 wide x 8-deep LED panel. Connection between modules is by a 4-wire Daisy-Chain. Control and data information is sent serially from your control equipment.
LED panels are available in heights of 50mm, 100 mm and 200 mm.
9-12V DC power is required.

Frequently, maintenance personnel have to replace a Photocell or Proximity Detector on a production line, but don't have the correct item in their  Toolbox. These inexpensive converters are simply connected in-line, and will convert from NPN to PNP

PNP-NPN Converters
As at left, but used to convert 'in the opposite direction'.
