Table 4.6.6 TIIS Explosion Proof Type Wiring Examples (Simultaneous Current-Pulse Output)
Connection Description
Simultaneous
Current-Pulse Output
When simultaneous output of current and pulse output are used, no communication is possible
in some cases. Refer to following example 1 to 3.
Example 1
In this case,
Communication is
possible (up to a
distance of 2 km
when a CEV cable
is used) and when a
two-wire or three-
wire shielded cable
is used.
No communication is possible
when a shielded cable is not used.
However, simultaneous current-pulse output is possible.
Shielded Cable
Distributor, etc.

Shielded Cable
For the shielded cables in this example,
use two-wire shielded cables
separately for SUPPLY and DO.
