How to find the right terminal module for a power module for your
application:
Screw-type terminal:
TM-P15S22-01
(2x2 terminals)
No
Yes
Do you
need access at this
terminal module to the AUX1
bus by means of terminals (for
example, for protective conductors or
additional supply of potential up to
the maximum load voltage of the
module)
?
Spring terminal:
TM-P15C22-01
(2x2 terminals)
Do you
want to interrupt the
AUX1 bus with this terminal
module and thus open a new potential
group
?
NoNoNoNo
Screw-type terminal:
TM-P15S23-A1
(2x3 terminals)
Spring terminal:
TM-P15C23-A1
(2x3 terminals)
Yes
Screw-type terminal:
TM-P30S44-A0
(2x3 and 2x4
terminals)
Spring terminal:
TM-P30C44-A0
(2x3 and 2x4
terminals)
Yes
Do you
want to use fail-safe
modules in this new potential
group
?
No
NoNoNo
Screw-type terminal:
TM-P15S23-A0
(2x3 terminals)
Spring terminal:
TM-P15C23-A0
(2x3 terminals)
Yes
