Description
Product Bulletin
The 2589-A 8/16/32-Point Universal Discrete Input
Module accepts a wide range of voltage signals. It is
designed to accept both AC and DC voltage allowing
the user to pick and choose ranges on a single
module. The 2589-A can be configured as an 8-point,
16-point, or 32-point module and can replace many
Siemens® input products with no rewiring. Motor
centers, optical sensors, limit switches and utility
control are excellent examples of applications for this
product.
Features
• CTI 2500 SeriesTM or Simatic® 505 base format
• 8. 16. or 32 universal input points
• Replaces Siemens® 505-4008-A, 4016-A, 4032-A,
4208-A, 4216-A, 4232-A, 4308. 4316. 4316-A,
4332. 4408-A, 4416-A, 4432-A with norewiring
• 1500V channel-to-PLC backplane and group-to
group isolation
• Wide 11V to 250V AC/DC range (selectable by
group)
• Isolation in groups of 4 or 8 (selectable on 2589-A)
• Sourcing or sinking inputs
• Single-wide module
The 2589-A was designed to be primarily a 32pt module. However, in order to provide maximum flexibility for the
user, it may be configured as an 8 or 16 point module. Some details below to help the user better understand
the jumper settings and labeling discrepancies for settings other than 32 points.
16 Point Mode: Move jumper in “Login” box to location
JP130 to choose 16pt mode. Ensure the Isolation
jumpers J3-6 are in Enhanced positions to corre
spond to the Siemens® 16 point modules (4 inputs/
common); otherwise two 18 or 20 ga. jumper wires
from AR to BR and CR to DR on the front panel
connector are needed (see Figures, pg 2) to allow for
8 inputs/common. Also, note that many of the printed
channels (CH 1-CH 32) on the PC board are no
longer valid, nor are the front panel connector labels,
or the LED channel indicators. (You may find it helpful
to manually relabel the connector in the space
provided for the 16 Point Login option.) If 16 Point is
enabled, the following table’s 16pt. row is the new
correlation of PC board and connector label printing.
For example, in 16 Point Login Configuration, the
board marking for channel 10 (CH 10) would be the
input channel 6. Likewise, the PC board marking for
CH 28 would correlate to input channel 16. CTI offers
an sticker you can apply to the front of the module
which updates the LED labels. Contact CTI and ask
for part number 506A-2588
8 Point Mode: Move jumper in “Login” box to location
JP131 to choose 8pt mode. Ensure the Isolation
jumpers J3-6 are in Enhanced positions to corre
spond to the Siemens® 8 point modules (2 inputs/
common); otherwise two 18 or 20 ga. jumper wires
from AR to BR and CR to DR on the front panel
connector are needed (see Figures, pg 2) to allow for
4 inputs/common. Also, note that many of the printed
channels (CH 1-CH 32) on the PC board are no
longer valid, nor are the front panel connector labels,
or the LED channel indicators. (You may find it helpful
to manually relabel the connector in the space
provided for the 8 Point Login option.) If 8 Point is
enabled, the following table’s 8pt. row is the new
correlation of PC board and connector label printing.
For example, in 8 Point Login Configuration, the
board marking for channel 10 (CH 10) would be the
input channel 4. Likewise, the PC board marking for
CH 25 would correlate to input channel 7. CTI offers
an sticker you can apply to the front of the module
which updates the LED labels. Contact CTI and ask
for part number 504A-2588 -8.
