The NetGuardian G4 alarm remote supports 32 discrete alarms, 8 analog inputs, 8 control relays, 7 RS232 serial ports, 1 RS485 port and an informative local LCD display all in a 1 rack unit of space. We've also drawn the front and back panel views of the new layout. The discrete alarms are items such as door alarms, equipment alarms and other ON/OFF events.
The discrete alarms are "software reversible" to support both N/O and N/C alarm wiring. The analog alarms are used for measuring critical events such as temperature and voltage (+/- 92VDC). Each of the alarms can be assigned qualification times so that transient and nuisance alarms can be filtered out. The controls are a convenient and time efficient way of remotely switching equipment in the field via the NetGuardian's internal relays.
Here, you'll also see the NetGuardian G4 DX Expansion Chassis for sites that require more than 32 discrete alarms. The NetGuardian DX expansion chassis is the perfect companion product to the NetGuardian G4. It's specifically designed to expand the discrete alarm capacity only and as such, provides a substantial savings over the expense of adding another NetGuardian G4 anytime you need the extra capacity. Each DX Expansion chassis increases the alarm capacity by 48 points for a total of 80 discrete contacts as well as 8 extra control relays. Up to 3 DX Expansion chassis can be daisy-chained for a total of 176 discrete alarms.
