Features
SDAMGUARD is the ideal monitoring system to inform the user in real time about the situation of his peripheral plant controlled through SDAMNet local network with SDAM-MED and/or SDAM Shut-off units; it supplies alarms, measurements and status.
SDAMGUARD manages and visualizes all information from SDAM units by local network RS 485.
SDAMGUARD is equipped with relay output, it can be configured for external cumulative alarm indicator, for external hooter or for telephone dialer.
