Protege DIN Rail
8 Output Expander

PRT-PX8-DIN

The 8 Output Expander extends the Protege system with an additional 8 outputs for automation.

Featuring high current Form C relays, the output expander provides extensive hardware advancements that allow flexible and structured control of building systems including lighting and HVAC.

  • 8 Form C relays capable of switching resistive loads up to 7 amps
  • Each output expander can monitor up to 8 trouble inputs
  • Ideal for connection in an electrical switch room to control signage, lighting and building automation

Features

Extending the Protege System with onboard local outputs allows convenient, cost effective expansion with the additional benefits:

  • 8 multiple-function outputs available for use in any programmable output configuration
  • Outputs can be configured to automatically turn on or resume their previous state upon restoration of power or communication failure
  • Address configuration is achieved using the address programming feature of the Protege System Controller.

Device power is supplied from a 12VDC input. Ultra low current requirements ensure cost-effective power distribution.

A single RS-485 communication interface port used for all network communication functions and interconnection to other modules.

The input expander features comprehensive diagnostic indicators that can aid in diagnosing faults and conditions. LED indicators on the input expander include:

  •  Status indicator
  • Fault indicator
  • Power indicator
  • Output indicators

Utilizing the latest flash technology and high performance communication mediums, the firmware can be updated via the Protege interface.

* The Total Combined Current refers to the current that will be drawn from the external power supply to supply the expander and any devices connected to its outputs. The Auxiliary outputs are directly connected via thermal resettable fuses to the N+ N- input terminals, and the maximum current is governed by the trip level of these fuses.
