FlipFlop120 for 120 VAC Systems
FlipFlop32 for DC Systems


  • Bi-stable or latching function to turn load on with momentary or maintained input signal.
  • Two output poles, independently convertible from normally-open to normally-closed.
  • Complete isolation between line, load, and logic terminals.
  • Compact size. DIN rail or panel mount.
  • LED status indicator for each output pole.
  • Regent’s 5 Year “No-Questions-Asked” Warranty.

Ideal for:

  • Alternating product flow on packaging lines between two conveyors or packers
  • Skipping every other cycle on a printing or gluing operation
  • Alternately diverting containers on a labeling or sealing line
  • Duplex pump control
  • Alternating between two timing cycles for filling or gluing
  • Alternating tool feed
  • Forward/Reverse cycle control

The FlipFlop is an all-solid-state relay which provides the flip-flop, or toggle function. The relay can provide alternate energization of solenoids, pneumatic valves, motor starters, solid-state control devices, and other industrial loads. The FlipFlop is a bi-stable relay, and is designed to replace electromechanical ratchet relays for improved reliability and speed.

The FlipFlop is pulse triggered, so control voltage may be momentary or maintained. Input can be provided by mechanical limit switches, proximity switches, photo-electric controls, programmable controller output modules or other solid-state devices. Relays can be cascaded to implement an n-stage binary shift register.






1. There is complete electrical isolation among Line, Load, and Logic circuits. They may be used in separate and different voltage
circuits or systems.
2. Terminals L2 (or -) and/or 2 may be grounded.
3. For loads greater than 1 amp, do not parallel solid-state switches. The current will not divide equally and may result in damage.
4. Normally-closed switches require power on L1,L2 (or +,-) terminals for proper operation.
5. Switching time delay is the delay between A,B turn-off and C,D turn-on (or vice versa) to prevent overlap.
