Notes on using the lampholders with separate lamp test
function
•Lamp test circuit,
• Interference suppression,
• Limiting voltage peaks,
• Limiting DC coils,
• Diode gates,
• Rectifier circuits.
When connected in parallel with
inductive loads (e.g. contactors), surge suppression required.
The diode element contains two
1N 4007 diodes. The element
can be snapped onto the holder
as required.
The 3SB14 00–2Q and
3SB34 00–1H elements are not
suitable for use with a parallel
load.
Typical push to test circuit using a standard,
illuminated pushbutton with 1 NO + 1 NC contact.
