● Electrically isolated to load voltage
Terminal assignment
The diagrams below show various wiring options.
Note
Note when wiring the SM 334:
analog ground
ANA
(terminal 15 or 18) is interconnected with chassis ground M of the
CPU or interface module IM.
Use a cable with a conductor cross-section of at least
1 mm
2
.
The module will shut down if the ground connection between M
ANA
and M is missing.
Inputs are read with 7FFF
H
, and outputs return a value of 0. The module may be
destroyed if operated without ground over a longer period of time.
the
supply voltage for the CPU and/or the interface module (IM) may not be connected
with reversed polarity
. Reverse polarity will inevitably lead to the destruction of the
module, because M
ANA
develops an impermissible high potential (+24 V.)
