    Active signal is issued when both lines present 0 V; a single line presenting 0 V for a duration longer than the test pulses is sufficient to signal an event. Some related terms: Electrosensitive protective equipment (ESPE) - a device such as a light curtain, safety scanner, or gate position sensor. The ESPE has OSSD outputs.

    If connected in series with the circuit it simply prevents reversed current, but if connected in parallel it can shunt the reversed supply, causing a fuse or other current limiting circuit to open. All semiconductor diodes have a threshold voltage – typically between 0.5 volt and 1 volt – that must be exceeded before significant current ...
