Simultaneous Current-Pulse Output (TIIS Explosion Proof Type)
Connection
Simultaneous
When simultaneous output of current and pulse output are used, no communication is possible
Current-Pulse Output
in some cases. Read the following example 1 to 3.
Example 1
In this case,
Communication is
possible (up to a
distance of 2 km
AXR Terminal
when a CEV cable
is used) and when a
two-wire or three-
wire shielded cable
is used.
Example 2
In this case,
Communication is
possible (up to a
distance of 2 km
AXR Terminal
when a CEV cable
is used) and when a
one-wire or two-wire
shielded cable is
used.
