Protege DIN Rail
8 Input / 4 Output Expander

PRT-IO84-DIN

The Protege DIN Rail 8 Input 4 Output Expander extends the number of inputs by 8, allowing monitoring of a wide range of EOL capable or open contact sensors; and extends the number of outputs by 4, featuring high current Form C relays for controlled automation of building systems including lighting and HVAC.

  • 8 monitored inputs
  • Connect any combination of normally closed or normally open inputs, configurable per input
  • Four-state input alarm using resistors to provide short, alarm, closed and tamper conditions
  • 4 Form C relays capable of switching resistive loads up to 7 Amps

Features

Extending the Protege system with local inputs and outputs allows convenient, cost-effective expansion with the following additional benefits:

  • 8 inputs can be assigned to any 4 areas in the system each being processed using different options or features
  • 4 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.

 

The input/output expander has 4 programmable Form C relay outputs which can be used to activate bell sirens, lighting circuits, door locks, relay accessory products and other automation points.

 

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

 

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

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

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