Select a Wiring Setup:

2-Wire, Unidirectional Pulse

The contacts transfer and reset when a unidirectional pulse is applied to the single coil using two (2) control wires. Available for AC & DC circuits.

2-Wire, Alternating Polarity

The contacts transfer and reset when the voltage polarity is alternated into the single coil using two (2) control wires. Available for DC circuits only.

3-Wire

The contacts transfer and reset when the voltage is alternated between two (2) control wires while utilizing a third (common) wire. This single coil has internal diodes. Available for AC circuits only.

4-Wire

The contacts transfer and reset when the voltage is alternated between two (2) unique coils using four (4) control wires. Available for DC circuits only.
