eBM-404 / eBM-404-H

Building Automation System enteliBus Module
The eBM-404 is an enteliBUSTM I/O Module with 4 universal inputs and 4 24VAC Triac outputs with optional monitored overrides. Auto detecting and hot swappable I/O Modules are selected to create the exact I/O combination needed for a given application. Should the application require the system to expand in the future, I/O expansion is easy to add.


The enteliBUS Control System is made up of multiple modular components that you select to meet the exact needs of a wide range of HVAC and Access control applications.

The enteliBUS I/O Modules provide the field I/O interface for the enteliBUS Control System. With I/O Modules supporting all common control types this allows the controller I/O mix to be easily and efficiently tailored to fit any application.


  • Auto detecting & hot swappable
  • Universal inputs (jumper configurable)
  • 0-100% LED status indication of each input state.
  • 3 position (HAO) monitored output override switches (optional)
  • Tri color LED status indication of each output state
  • Small footprint, DIN rail mountable
  • Modular design provides flexibility, ease of service, and reduced cost for future upgrades/expansion


4 Universal inputs (12 bit), jumper configurable for:

  • 0-5 VDC, > 1MΩ loading
  • 0-10 VDC, 20KΩ loading
  • 10 KΩ Thermistor, 10KΩ to 5VDC
  • Dry Contact (using 10 KΩ jumper setting)
  • 4-20 mA, 250Ω to Gnd

LED status indication of each input:

  • Black = 0% to Bright Blue = 100%


4 Binary Triac outputs
