The SM IO module provides monitoring of auxiliary equipment such as climate control units through detailed information and alarms. When maintenance is performed using the information from SM IO, time and money can be saved especially for remotely located sites. The SM IO connects to the DC power system's control unit and monitors auxiliary units. Information and alarms regarding the auxiliary equipment can be monitored through a web browser or management software. Benefits include lower maintenance costs and higher availability through remote monitoring and control of site equipment.

DC Power System
Monitoring
Supervision Module for generic
monitoring
The Supervision Module for generic monitoring provides
detailed information and alarms regarding the condition and
status of auxilary equipment such as climate units or building
alarms. When maintenance and site visits related to the auxiliary
units upon this information they can be optimized to save both
time and money, especially for sites located remotely.
The SM IO is an easily installed monitoring device connected
to the integrated control unit (ACU1
) of the DC power system,
and the auxiliary units it supervises. It is designed mainly for
measuring alarms, voltages and temperatures.
The information and alarms, regarding the auxiliary units on a specific site,
can be monitored or checked by means of a simple web browser or specific
management SW2
. No additional software is needed and the web browser
login to monitor the site is password protected. (Examples of alarms
provided by means of the control unit of the power system is specified in
the datasheet and/or manual for the specific unit.)
Benefits
• Lower maintenance costs related to equipment monitored and/or
controlled by SM IO
• Higher availability thanks to remote monitoring and control
of site equipment
