Environmental Rack Monitor for 120 VAC Racks

The Eaton 103005775 Environmental Rack Monitor is designed for data-centre operators and IT managers who need continuous visibility of rack-level conditions. It mounts in unused side or rear channels and connects to a standard US 2-pin 120 VAC supply. The unit tracks temperature and humidity at two points plus the status of up to four dry-contact sensors. A 16-bit microcontroller with 2 MB static RAM and 2 MB flash ROM drives the monitoring functions.

Sustained Operation with Dual Serial and Ethernet

Under continuous duty the monitor maintains two asynchronous serial ports and an auto-sensing 10/100 Mbps Fast Ethernet controller with an RJ-45 jack. The 16-bit CPU handles persistent polling of the TH-Module sensors and contact inputs without dropping logged events. Flash ROM retains configuration and history across power cycles so the device resumes monitoring immediately after any interruption.

Passive Cooling and Low Power Draw in Normal Use

The compact 5.3" x 3.4" x 1.1" enclosure weighs 6 oz and operates without fans, relying on natural convection in the rack airflow. Power consumption stays minimal because the 16-bit microcontroller and 10/100 Ethernet PHY draw only the current needed for sensor polling and network keep-alives. No audible noise is produced, making the unit suitable for dense rack rows where acoustic limits apply.

Questions about this item

How much power does the Environmental Rack Monitor 103005775 draw when running continuously?

The unit operates from a 120 VAC two-pin supply and uses a 16-bit microcontroller with 10/100 Mbps Ethernet, so idle consumption is very low.

What connections must already be in place for the ERM to start monitoring?

You need a 120 VAC outlet, a free RJ-45 network drop, and the two TH-Module sensors placed at the rack locations you want watched.

Will the ERM 103005775 work with an older UPS that only has a DB-9 serial port?

Yes, the monitor provides two asynchronous serial ports that can cable directly to legacy UPS or PDU serial interfaces.
