About this component
A dual-coil latching relay with two isolated changeover contact sets operated together. Separate SET and RESET windings control both poles, allowing one stored relay state to switch two independent circuits. 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

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

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 A
Common terminal of pole A, electrically isolated from the coils and pole B.
6
NO A
Pole A contact selected in the set state.
7
NC A
Pole A contact selected in the reset state.
8
COM B
Common terminal of pole B, electrically isolated from the coils and pole A.
9
NO B
Pole B contact selected with NO A by the shared latched state.
10
NC B
Pole B contact selected with NC A by the shared latched state.
