2.5 — Digital Outputs and Inputs.
ELNet LT
Energy & Powermeter has as default 1 Digital Output and
2 Digital Input connections at its back side (additional IO can be
implemented by using additional external modules).
Digital Output:
The Digital Output of the LT 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 LT (cannot be used for both
simultaneously). The Digital Out closes contact of SSR between pins 4 and
5, the maximum load is 150mA.
Digital Inputs:
In order to change the status of the Digital Inputs of the LT a 220 VAC
contact must be provided. The indication voltage should be supplied from
one of the measured phases. The digital inputs can be monitored by
communication and appear at the communication list.
