9.12. Binary I/O on IS-BIN16/8
9.12.1. Binary inputs on IS-BIN16/8
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.
A 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.
