DETAILED DESCRIPTION
Pulse Triggering
If input is driven by square pulse, connect the inputs to the pulse source directly. Relay will operate as logic table
stated (Vin should be less than the power supply voltage, Rs is current-limiting resistor, it can be ignored in the voltage
is below 20V, i.e. Rs=0).
The recommended pulse width=100ms. The length of the intervals should be longer than 100ms. These intervals
include: intervals between forward drive pulse and next backward drive pulse, intervals between forward drive pulse
and next forward drive pulse, intervals between backward drive pulse and next forward drive pulse, intervals between
backward drive pulse and next backward drive pulse.
