Fig. 1. The NetGuardian E16 DX G2
Discrete Alarm and Control Relay Expansion Solution
The NetGuardian E16 DX G2 expands the capacity of the NetGuardian 832 G5 platform (including the 864A) by 16
alarm points and 16 controls.
The E16 DX G2 interfaces to either:
· An RS232 serial ports on the NetGuardian 832A G5 that is configured for point expansion, or
· An RS232 serial port on a NetGuardian 864 DX that is already daisy-chained onto a base NetGuardian.
NOTE: Only a single E16 DX G2 may be connected to a base NetGuardian, and it must be the last expansion in a
daisy chain. Because the E16 DX G2 has only an input serial port and no output serial port, it can only attach itself
to the end of a chain.
Fig. 2. An expanded RTU. The NetGuardian 864A G5 (top) has been supplemented by 2 NetGuardian 864DX units
(middle) and a NetGuardian E16 DX G2 (bottom). This configuration has a total of 208 alarm inputs and 40 control
relays. Both of the 864DX units are optional expansions.
Dual, separately fused -48V power
For protection against power failures, the NetGuardian E16 DX features dual redundant -48vdc power supplies.
