Multi-function input terminal
X1
Multi-
function input
terminal 1
It can be defined as
multi- function on-off
input terminal. See
section 5.4 (Group P3),
Chapter 5 for the
function of input
terminals
(The common terminal
is PLC)
Optical-isolator input
Input resistance:
R=3.9 kΩ
Maximum input
frequency: 400 Hz
Input voltage range:
0~30V

Multi-
function input
terminal 2
X3
Multi-
function input
terminal 3
X4
Multi-
function input
terminal 4
In
S2R4GB~3004GB/35R
5PB, terminals X4 and
X5 can be used as
common multi-function
terminals, they can also
be used as high
frequency pulse input.
In 35R5GB/37R5
PB~3500G, they only be
used as common multi-
function terminals
See section 5.4, Chapter
5 for details.
