Terminal assignment
The diagrams below show various wiring options.
Note
Note when wiring the SM 334:
• analog ground M
CPU or interface module IM. Use a cable with a conductor cross-section of at least
1 mm
The module will shut down if the ground connection between M
Inputs are read with 7FFF
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

(terminal 15 or 18) is interconnected with chassis ground M of the
