Proteus Help - Latching Relay

Not open for further replies.


New Member
I'm new to Proteus but desperately need to simulate a dual coil latching relay. Specifically, I'm using a HFD2/005-M-L2 from Hongfa.

Need this to be an active component so I can run simulations. How do I go about this?

You make a sub circuit that contains the extra parts... Do you need a single pulse or separate on / off??

A simple JK flipflop will give both operations...

One thing to remember on Proteus.... A relay or switch cannot switch in a power rail... It does not work!!

Can you generate the SET, RESET pulses 5V 40mA for 5 ms min. ?

At 200mW this should be possible to leave power on but intended for pulse operation.
