Half DIN Rail 8 Output Expander


The Protege Half DIN Rail 8 Output Expander provides the control of 8 high current Form C relay outputs to the Protege system, an advanced technology security product providing seamless and powerful integration of access, security and building automation. The Output Expander provides extensive hardware advancements that allow flexible and structured control of lighting and HVAC systems and is designed for use with industry standard DIN Rail mounting.

Key Features:

Power Supply

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

Small Footprint

The compact two-tier half DIN Rail module design takes up less valuable real estate to provide more control in less space.

Connectivity and System Expansion

Expanding the Protege System with outputs from the Protege Half DIN Rail 8 Output Expander allows convenient cost effective expansion and added benefit of:

  • 8 multiple function outputs for use in any programmable output entry
  • Ideal for connection in an electrical switch room to control signage, lighting and building automation
  • Address configuration is achieved using the address programming feature of the Protege System Controller
  • Outputs can be configured to automatically turn on or resume their previous state when powered up or during a communication failure


Single RS-485 communication interface port used for all network communication functions and interconnects to other modules.

Upgradable Firmware

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 Output Expander and any devices connected to the expander's outputs. The Auxiliary outputs are directly connected via electronic fuses to the N+ N- input terminals, and the maximum current is governed by the trip level of these fuses.
