Stampa la paginathe total current of all "B" terminals
must not exceed 200mA. If the voltage
measured from the "B" terminal to Gnd
is less than 18VDC, you need to use an
additional external power supply.
• Dry Contact: A 5VDC wetting voltage is
used to detect contact position. This
results in a 0.5mA maximum sense
current when the contacts are closed.

The M4106nx accumulates up to ten input
pulses per second.
1. Be sure the M4106nx's power is off before
wiring any inputs or outputs.
2. Connect the input wiring to the screw
terminals on the module as shown in
Figure 7.
NOTE If a 4-20 mA sensor uses an
external 24VAC power supply, connect
one leg of the 24VAC supply to the module
ground.
3. Set the configuration jumper for each
input to indicate the type of input
used.Make sure the jumper is positioned
correctly, and be sure to grip the jumper
by the sides only. See Figure 8.
4. For each input, enter the channel number,
offset, and gain on the Function Block's
Parameter page in SuperVision. Valid

channel numbers are listed in "Channel
Numbers" on page 8.
5. To verify each input's operation, have
each sensor create a known value and
compare it to the condition reported on
the FB's Status page.
