Abstract
An industrial solid state logic system having a device for translating low level input signals into high level output signals, the components of the device being arranged so that an output switching unit responds only to current flowing from a source when fed from a logic gate which is adapted to sink current although it has the capability to source current. A light emitting diode is connected in a circuit of the device to indicate the electrical condition of an output switching component of the device.
