Repair Policy
In the event that the Product should fail during or after the warranty period, a Return Material Authorization
(RMA) number can be requested orally or in writing from CTI main offices. Whether this equipment is in or
out of warranty, a Purchase Order number provided to CTI when requesting the RMA number will aid in
expediting the repair process. The RMA number that is issued and your Purchase Order number should be
referenced on the returning equipment’s shipping documentation. Additionally, if the product is under warranty, proof of purchase date and serial number must accompany the returned equipment. The current repair
and/or exchange rates can be obtained by contacting CTI’s main office at 1-800-537-8398.
When returning any module to CTI, follow proper static control precautions. Keep the module away from
polyethylene products, polystyrene products and all other static producing materials. Packing the module in its
original conductive bag is the preferred way to control static problems during shipment. Failure to observe
static control precautions may void the warranty. For additional information on static control precautions,
contact CTI’s office at 1-800-537-8398.

Description
Turn On Time: 1 AC cycle
The 2598-8 8-Point AC Discrete Output Module
provides eight outputs isolated in groups of
two from the CTI 2500 Series or Simatic® 505 I/
O base. The module utilizes solid-state output
circuits to switch on or off external devices such
as pilot lamps, motor starters, or solenoids. The
2598-8 is designed to switch externally supplied
11 to 240 VAC. The internal logic signals are
isolated from the external outputs to 2100 VDC.

Channel Configuration Explanation
The 2598-8 was designed using a PCB that could also perform as a 16 or 32pt module. Hence, the PCB printing
for channels do not line up with actual 2598-8 channels. See chart below for the proper correlation of channels. For
example, if the module reported channel 4 was blown, then the user would replace the fuse marked ‘CH 10’ on
the PCB.

Grouping Configuration
The 2598-8 is shipped to allow two channels to be grouped and share a common field user power, thereby allowing
a different user power supply voltage to be used by each grouping. Jumpers J2, J4, J6, and J8 come
set in the “8 common” selection from the factory and should not be altered for proper module operaton. This
setting allows for 2 points per common operation.
Figure 3. Typical External Wiring Diagram
For example, Channels 1-2 will share a common user power and Channels 3-4 will share another common user
power. In this example each group of two channels is isolated from the other group of two channels. Because each
group of two is isolated, the user may also change the supply voltage for each group. So, in this example, Channels 1-2 could be 240VAC outputs and Channels 3-4 could be 120VAC outputs.
