Extension Unit Application Rules
All the following rules apply for both the PSSEXT1 and PSSEXT3
extension unit.
• For all adapters:
– Up to four extension units can be used per network adapter.
• The fi rst module after an extension unit must be a PSSSE24A.
– A PSSSE24A is needed:
– if additional backplane power is needed because of module
current consumption, or
– after 2 extension units.
The only exception to this rule is if the modules in the segment
after the extension unit are only PSSTR4M12As. If only this
module is used, NO PSSSE24A is needed. In this case, the Pin
1 on PSSTR4M12A will NOT have 24VDC. Thus load must be
powered by external power. See E109P, Relay Output Module
Instruction Sheet for details.
• The number or mix of modules you use between extension cables
does not matter as long as you do not exceed the rated adapter
or PSSSE24A current output.
