Title:
CONTROLLER INPUT/OUTPUT MODULE VISUAL INDICATOR AND SAFETY MEANS
Document Type and Number:
WIPO Patent Application WO2003019306
Kind Code:
A3
Abstract:
A controller input/output module visual indicator and safety means including a light redirector (103), terminal block assembly (111) and at least one circuit (105) having at least one light emitting diode or like light transmission means (107b) positioned distally from the terminal block assembly. Each light redirector (103) is configured to receive light from each corresponding light transmission means (107b) on a proximate end and redirect the light information to a distal end adjacent to the terminal block assembly for viewing by the control operator. An optional shield or side barrier may optionally be coupled to the circuit to provide operator safety from the high voltage signals which may exist on each input/output module.
