Digistart IS

 
 

Fire mode

Digistart IS has an in-built fire mode. This is used in HVAC applications to help protect building occupants in the case of fire by pressurising escape routes to maintain a smoke free environment. Activation of this feature disables the soft starter protection ensuring it continues to run for as long as possible.

Powerthrough operation

Digistart IS’s powerthrough operation ensures the soft starter will continue to operate using 2 phases if one of the power devices is damaged. This allows you to keep your plant running whilst a long term fix is found.

Increased output

The Digistart IS allows the motor to be connected either in-line (three wire) or using an inside delta configuration (six wire). Inside delta configuration increases the power of the soft starter, meaning a smaller unit can be used. This is a compact, cost efficient solution when replacing star/delta starters where existing wiring can be used.

Other advanced features

  • Forward/reverse jog for low speed manual machine positioning
  • DC braking to electrically brake high inertia machines
  • Profibus, DeviceNet and Modbus RTU communications
  • Expandable I/O

Description
Digistart IS - Keypad mount kit This allows the keypad to be remote mounted up to 3m from the soft starter. When panel mounted the keypad is IP65 rated.
Digistart IS - Fingerguard Finger guards are available to provide IP20 protection for models IS2x0145B to IS2x0220B.
Digistart IS - I/O Expansion Provides additional 2 x digital inputs, 3 x relay outputs, 1 x analog input and 1 x analog output.
Digistart IS - RTD & GND Fault Card The RTD (resistive temperature device) and GND (ground fault protection) card provides additional 6 x PT100 RTD inputs and 1 x ground fault input.
Digistart IS - Volt Measure Card Allows real-time monitoring of mains voltage, eliminating the need for external devices. The volt measure card also enables under voltage and over voltage protection.
