Binary inputs
There are two groups of eight Binary inputs BI1 to BI8 and BI9 to BI16. Each group has a separate Common
terminal COM1 and COM2. The Common terminal can be connected to positive or negative pole – see following
drawing. Binary inputs are galvanically separated from IS-BIN16/8 power supply.
Note: Theory of binary inputs and outputs (page 347) (Pull Up,Pull Down, High side switch, Low side
switch)
Binary inputs Common terminal is connected to
positive supply terminal, Binary inputs contacts are
closed to negative supply terminals.
Binary inputs common terminal is connected to
negative supply terminal, Binary inputs contacts are
closed to positive supply terminals.
Input voltage range for opened contact is from 8 VDC to Power supply VDC. Input voltage range for closed
contact is from 0 to 2 VDC. Voltage level is defined between Binary input and Binary input COM terminal and
does not depend on “positive” or “negative” connection.
Impulse inputs do not work with IGS-NT controller.
Binary output
The Common terminal can be connected to positive or negative pole (HW3.0 only) – see following drawing.
Binary outputs are galvanic separated from IS-BIN16/8 power supply (have a look at technical data). The
maximum load values are 0.5 A / 36V for one output.
Binary output common terminal is connected to negative
supply terminal, Binary output contacts are closed to
positive supply terminals.
Binary output common terminal is connected to
positive supply terminal, Binary output contacts are
closed to negative supply terminals.
