The diode + resistor network
It eliminates the inconvenience of the resistor alone, explained above, and it limits the action of a single diode. It is now
preferred to used the diode + zener network.
The diode + zener network
Like the resistor, the zener allows a faster decurrent decay. In addition it introduces a threshold level for current conduction
which avoids the recycling of energy released during contact movement.
The lower curve on the opposite record demonstrates those characteristics. Voltage limitation occurs at 42V. The two voltages
spikes generated by internal movement are at lower levels than zener conduction. As a result, no current is recycled in the
coil.
The opening time phases are as follows:
- time to start the movement 2.6ms
- total motion time 2.4ms
- transfer time 1.4ms
The release time is slightly increased. The contacts' opening speed remains unchanged.
