NEXSYS® Component Technology – Electronic Switching

Electronic Rotary

Electronic Rotary

The Electronic Rotary is an 8-pin electronic switching component that is customer configurable to replace a standard rotary device and can be integrated in a VIVISUN® High Capacity switch body or can be included in a stand-alone NEXSYS® Module for use behind the panel. The Electronic Rotary (ER1) can be configured as a 2, 3 or 4 state rotary switch.

  • Configurable inside of VIVISUN® High Capacity switch bodies and NEXSYS® Modules.
  • Four electrically separate control states
  • Sink up to 2 amps with a resistive load
  • Advance to the next state on each high to low transition
  • Unit remains operational with power drop out up to 200 ms
  • All inputs are diode isolated and internally pulled up

How it Works

The Electronic Rotary eliminates the need to use multiple components or complex software to cycle through progressive states. Each unit is capable of 2, 3 or 4 latched states and the designer determines the configuration by routing the next highest output back to the reset input.

Component Features

Logic Input Circuit: Provides a reliable diode isolated, buffered and debounced input interface. The inputs are internally pulled up to approximately 18V. This provides simple reliable operation with either external switches or open drain drivers.

Latch Circuitry:Proven reliable counter decoder that holds the current state until commanded to increment or reset.

Logic Output Circuitry: Provides ground switched open drain output drivers that are both fused and surge protected.

Power Supply: Efficient internal regulated supply that allows the unit to operate reliably on less than 5 mA.
