About this component
A latching relay with separate, electrically isolated SET and RESET windings and one changeover contact set. A positive current pulse in either winding selects its corresponding state, which remains selected after coil current stops. Each simulation starts reset. Simultaneous operating pulses use reset priority.
Parameters
Basic settings
6 parameters
SETCOILRESISTANCE
Set coil resistance
Series resistance of the isolated SET winding.
125 Ω
SETCOILINDUCTANCE
Set coil inductance
Series inductance of the SET winding; its time constant is inductance divided by resistance.
50m H
RESETCOILRESISTANCE
Reset coil resistance
Series resistance of the isolated RESET winding.
125 Ω
RESETCOILINDUCTANCE
Reset coil inductance
Series inductance of the RESET winding; its time constant is inductance divided by resistance.
50m H
SETCURRENT
Set current
Positive SET+ to SET− current that selects NO. Must be positive.
20m A
RESETCURRENT
Reset current
Positive RESET+ to RESET− current that selects NC. Reset has priority when both windings operate. Must be positive.
20m A
Advanced
2 parameters
ONRESISTANCE
Contact on resistance
Resistance of each selected contact path.
0.1 Ω
OFFRESISTANCE
Contact off resistance
Resistance of each open contact path. Keep greater than the on resistance.
1e9 Ω
Pins

7 pins
1
SET+
Positive terminal of the SET winding. Sufficient positive current selects NO.
2
SET−
Return terminal of the isolated SET winding.
3
RESET+
Positive terminal of the RESET winding. Sufficient positive current selects NC, with reset priority.
4
RESET−
Return terminal of the isolated RESET winding.
5
COM
Common terminal of the electrically isolated changeover contact.
6
NO
Connected to COM in the set state, including with both coil currents at zero.
7
NC
Connected to COM after reset and at the start of each simulation.
