Notes
Both drawings show examples for the I/O modules equipment.
I/O module connection:
– The maximum capacity of terminals for stranded or solid
conductors is 1 mm
2
(17 AWG).
– The stranded conductor may be tinned on the tip or twisted
for simplified connection.
– When using wire end ferrules the total section should not
exceed 1 mm
2
, i.e. the maximum stranded conductor section
is 0.5 mm
2
. The Weidmüller PZ 6/5 crimping tool must be
used for crimping the ferrules.
Functional scope of the Ethernet interface:
– Communication with configuration software ECT for gas
analyzer configuration and software update.
– QAL3 data transfer if the QAL3 monitoring option is integrated
in the gas analyzer.
