More Information

Overview Manuals Contactor Interface Pickup Forcing Current Regulation Dropout Circuit

Features:

  • Adapts two EAUX 41DC circuits for low-voltage high-speed contactors.
  • Uses brief voltage forcing to shorten contactor pickup time.
  • Regulates holding current through closed-loop pulse-width modulation.
The daughterboard changes the EAUX output behavior only for installations fitted with the specified low-voltage contactor coils.

Pickup and hold are separate electrical stages: a short high-voltage interval moves the armature, then PWM limits continuous coil current.

During release, the flyback route changes so stored coil energy is directed through the EAUX discharge path instead of maintaining current.

Identify the EAUX host and contactor-coil class before applying General Electric IS200EAUDH1A to either 41DC driver channel.
General Electric IS200EAUDH1A High-speed Contactor Driver Daughterboard Manuals,Datasheets,Link Important Notice: Distinguish low-voltage high-speed coils from standard 125 V dc contactors before applying EAUD driver information.

How EAUD changes the EAUX output

  • Host Board: The daughterboard mounts directly on an EAUX board.
  • Circuit Count: Two 41DC contactor-driver channels are supported.
  • Coil Class: The interface is intended for 30-32 V dc low-voltage coils.
  • Standard Mode: Systems using 125 V dc contactors or breakers do not require EAUD.

The first stage of contactor operation

  • Initial Voltage: The full 125 V dc source is applied at pickup.
  • Forcing Time: The boosted interval lasts for the first 150 ms.
  • Mechanical Effect: Higher initial voltage accelerates contactor armature movement.
  • Mode Transfer: The circuit changes from forcing to regulated hold after pickup.

Closed-loop holding behavior

  • PWM Rate: The hold stage switches at 1.5 kHz.
  • Current Target: Closed-loop control regulates coil current to 1.5 A.
  • Feedback: Measured coil current sets the PWM duty cycle.
  • Off Cycle: A low-impedance flyback path carries current between switching pulses.

Removing stored coil energy

  • Stop Command: The flyback path is disabled when the driver turns off.
  • Energy Release: Coil energy then flows through the EAUX discharge resistor.
  • Rapid Opening: The discharge arrangement supports fast contactor dropout.
  • Board Coordination: EAUD and EAUX act together during both drive and release states.
Description
Mounted on an EAUX auxiliary-interface board, General Electric IS200EAUDH1A is the EX2100e High-speed Contactor Driver daughterboard. It converts two 41DC driver circuits from the standard 125 V dc coil mode to the interface required by low-voltage high-speed contactors.

At a pickup command, IS200EAUDH1A applies the full 125 V dc source to a 30-32 V dc contactor coil for the first 150 ms. This voltage forcing accelerates armature movement before the circuit changes to its holding mode.

After pickup, IS200EAUDH1A uses 1.5 kHz pulse-width modulation and coil-current feedback to regulate current to 1.5 A. A low-impedance flyback path controls the coil current during the off portion of each PWM cycle.

When a stop command is issued, the IS200EAUDH1A flyback path is disabled and the EAUX discharge resistor removes coil energy for rapid dropout. The daughterboard is not required when the EX2100e installation uses standard 125 V dc contactors or breakers.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why would an EX2100e installation include IS200EAUDH1A?
IS200EAUDH1A is added when the EAUX 41DC circuits must operate low-voltage high-speed contactor coils rather than standard 125 V dc contactors or breakers.
What happens during the first 150 ms after IS200EAUDH1A receives a pickup command?
IS200EAUDH1A applies the 125 V dc source across the low-voltage coil for 150 ms so the contactor can pull in quickly.
How does IS200EAUDH1A avoid holding a 30-32 V coil at the forcing voltage?
After pickup, IS200EAUDH1A changes to 1.5 kHz PWM and uses current feedback to regulate the coil at 1.5 A.
What should be checked if a contactor releases slowly with IS200EAUDH1A installed?
Verify that the IS200EAUDH1A flyback path disables on stop and that the EAUX discharge resistor remains connected to remove stored coil energy.
Can IS200EAUDH1A be selected only from the contactor current rating?
No. Match IS200EAUDH1A to the EAUX host, the two 41DC circuits and the specified low-voltage high-speed coil arrangement, not current alone.
