3.7 Connecting the Signal Lines
W WARNING
• To prevent electric shock, always make sure that the power supply is
turned OFF before connecting.
• When 30 VAC or 60 VDC and more is applied to the output terminal of
the alarm module or the output terminal of the DI/DO module, use
double-insulated wires(withstand voltage performance: more than 2300
VAC) for those wires which apply 30 VAC or 60 VDC and more. All
other wires can be basic-insulated(withstand voltage performance: more
than 1350 VAC). Furthermore, use “crimp-on” lugs (for 4 mm screws)
with insulation sleeves for connecting to the screw terminal. Make sure
that the crimp-on tool must be one specified by the crimp-on lugs
manufacture, and that the crimp-on lugs and tool must be matched to
the wire size. To prevent electric shock, do not touch the terminal after
wiring and make sure to re-apply the cover.
CAUTION
• Do not apply an input voltage exceeding the following levels to each
terminal of each module. Otherwise, the internal circuits may be
damaged.
Allowable input voltage
Universal or DCV/TC/DI input module
2 VDC range or less, RTD, TC and DI(CONT) : ±10 VDC
6 to 20 VDC range, DI(LEVEL) : ±60 VDC
Digital Input module
CONT(Voltage-free contact input) : ±10 VDC
LEVEL(Voltage input) : ±60 VDC
mA-input module : ±5 VDC
Strain input module : Don’t input voltage to the terminal.
Pulse input module : 5 VDC
DI/DO module : –2 to 7 VDC
Max. common mode noise voltage
Universal, DCV/TC/DI input, digital Input, mA-input modules : 250
VACrms (50/60 Hz)
• Output contact rating for DI/DO or Alarm input modules is 250 VDC/0.1
A (resistive load), 250 VAC/2 A (resistive load), 30 VDC/2 A (resistive
load).
• The overvoltage category of each input module is CAT ll (IEC 1010-1).
• When connecting to a clamp terminal, use a signal conductor with the
following cross-sectional width:
Solid conductor 0.14 to 2.5 mm
2
Stranded conductor 0.14 to 1.5 mm
2
AWG 26 to 14
