Fig. 31: Overview terminal connectors Type XI - Intrinsically Safe applications
•
Type PC:
offers - additional to type PX - an internal Intrinsically Safe lithium battery. This ATEX
certified battery (FW-LiBAT-xxx) may be changed in hazardous area.
•
Type PD:
offers with terminal 6 - additional to type PX - a real sensor supply of 8.2V DC to power
a Namur sensor for example.
•
Type PX:
as standard, all intrinsically safe products are supplied with terminal 4 and 5 to power
the product externally.
