2.5 Digital Outputs and Inputs.
ElNet GR/PQ
Energy Powermeter & Power Quality
Analyzer has as default 3 Digital Output and 5 Digital Input
connections at its back side (additional IO can be implemented by using
additional external modules).
Digital Output:
The Digital Output of the GR/PQ can be used to transmit pulses of
energy to external BMS controller (chapter 4.6) or to close contact upon
alarm (chapter 5.4.3) which can be defined in the GR/PQ (same output
cannot be used for both simultaneously). The Digital Out closes contact
of Relay between pins 1/2/3 to 4c, the maximum load is 1 Amp.
Digital Inputs:
In order to change the status of the Digital Inputs of the GR/PQ a 220
VAC contact must be provided. The indication voltage should be
supplied from one of the measured phases. The digital inputs status can
be monitored by communication.
