The Protege DIN Rail 8 Input Expander provides the interface of up to 8 inputs (16 using Input Duplex Mode) for monitoring and automation in the Protege system. With 8 inputs that can be used for extended monitoring functionality, the DIN Rail 8 Input Expander provides extensive hardware advancements that allow flexible input programming and configuration, and is designed for use with industry standard DIN Rail mounting.
Device power is supplied from a 12VDC input. Ultra low current requirements ensure cost effective power distribution.
Expanding the Protege System with local inputs from the Input Expander allows convenient cost effective expansion and the added benefits of:
A single RS-485 communication interface port used for all network communication functions and interconnects to other modules.
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.
