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. InputA InputB Pulse width =100ms Pulse width =100ms Interval interval Forward drive/OPEN Backward drive/CLOSE InputA InputB Pulse width =100ms interval Forward drive/OPEN Forward drive/OPEN Pulse width =100ms interval
