2.2.6 Digital Inputs
There are two possible module types:
a) 16 Digital Inputs,
b) 16x2 (32) Digital Inputs.
Optically isolated digital inputs in one digital input module are provided for status monitoring and external
synchronization of power demand period and time. Dry or wet contacts may be connected to these inputs, as
shown in Figures 2-10, 11, 12, and 13.
In 16-DI Variant the common terminals are internally connected together, in 32-DI variant the module has
8 independent isolated circuits, containing 4 inputs with one common terminal.
