INPUTS OUTPUTS
1. SINK/SOURCE current, 24 V d.c. drive. The
SINK/SOURCE current connection for the inputs can
be selected by connecting the in
terminal.

feat
ures specifications that are compatible
with the "TYPE 1" digital inputs as defined in
the Standard EN61131-2.
WARNING
The machine inputs must be supplied by a
SELV (Safety Extra Low Voltage) power
source, as defined in the Standard EN60950-
N.B.
The “SINK current” input is driven by a switch
or limit switch connected between the input
itself and the positive pole of the machine I/O
power supply. The SOURCE current input is
driven by a switch or limit switch connected
between the input itself and
the negative pole
of the machine I/O power supply.
Relay with N.O. contact (Normally Open = closed
when active)
• Maximum current per contact: 3 A, with
restive load
• Maximum relay common contact current:
3.5 A
• Maximum voltage: 250 V a.c. r.m.s., 50-60
Hz (-6% / +5%) or 30 V d.c.
• Parasitic current for each open contact: 2
mA max (250 V a.c.)
ATTENTION
The outputs are not protected: install on the
shared outputs a magnetothermic protection
device with nominal current not greater than
In= 4A, characteristic “B” in compliance with
EN60947 and magnetic trigger current not
greater than 4 In= 16A or an equivalent fuse.
It is left to the user's discretion whether to
protect the individual outputs with a suitable
device. The power supply should also be
fitted with a differential circuit breaker
