FDM128 Display

The FDM128 is an intelligent Ethernet touch screen. It collects the data from devices via the Ethernet network. It is designed to manage up to eight devices such as:

  • Masterpact MTZ1,MTZ2, MTZ3, NT, and NW circuit breakers

  • PowerPact P- and R-frame circuit breakers

  • PowerPact H-, J-, and L-frame circuit breakers

The FDM128 switchboard display unit can be connected to a Micrologic X control unit via an IFE or an EIFE interface module. It is easy to use and requires no special software or programming.

The FDM128 has a large screen which requires little depth for mounting or installation. The anti-glare graphic screen has a backlight for easy reading even under poor ambient lighting and at sharp angles.

Display of Micrologic X Measurements and Trips

The FDM128 is intended to display the Micrologic X control unit measurements, trips and operating information.

  • The FDM128 cannot be used to modify the protection settings.

  • Measurements are easily accessed via a menu.

  • Trips are automatically displayed.

  • A pop-up window displays the time-stamped description of the trip.

Status Indications

When the circuit breaker is equipped with the Command Module, the FDM128 display can also be used to view circuit breaker status conditions:

  • ON/OFF (OF)

  • Spring loaded (CH)

  • Overcurrent trip indication (overload, short circuit, ground fault) (SDE)

  • Cradle management with EIFE (CE, CD, CT)

Remote Control

When the circuit breaker is equipped with communicating XF, MX, or MN devices, the FDM128 display can also be used to control the circuit breaker (initiation of open/close commands).
