For many years, the PLC 2/30 was a factory workhorse,
used by many conveyor companies and system integrators
throughout the U.S. and world-wide. However, its basic
design is over 25 years old, and its better times are
behind it.
The bad news is two-fold:
-
When Allen-Bradley wants to discontinue a product,
they raise its price considerably. The current
distributor price for a no-warranty, refurbished
PLC 2/30 with 16K of RAM is over $17,000.00!
-
Current replacements for the refurbished units
have a 7-8 week delivery time.
Can you tolerate your automatic production line being
down for 7 to 8 weeks due to a lightning strike or
other electrical power surge in your plant?
Here's the good news:
-
Any PLC 2/30 can be replaced with a PLC 5.
-
Your existing I/O rack and modules stay in place.
The PLC 5 will use the rack slot that is currently
occupied by the SD2 Scanner Distribution module.
-
Since the scan rate of the PLC 5 is about
4-5 times faster than the PLC 2/30, any load
positioning or load centering that was dependent
on scan rate will improve.
Here's more good news:
-
Control Engineering has already converted two
PLC 2/30 strapping systems to use the PLC 5/20.
-
The cost of converting a PLC 2/30 strapping
system to use a PLC 5/20 is about the same price
of a single refurbished PLC 2/30.
-
You get an EEPROM with the PLC 5 for
non-volatile program back-up.
Control Engineering will also convert your existing 5TI,
GE Series 1, or other mini-PLC's to a new Allen-Bradley
SLC 500 series processor!
