2598 8/16-Point
AC Discrete Output Module
Description
The 2598 8/16-Point AC Discrete Output Module
provides eight or sixteen outputs from CTI 2500
Series® or Simatic® 505 I/O bases. The module
utilizes solid-state output circuits to switch on or off
external devices such as pilot lamps, motor starters,
or solenoids. The 2598 is designed to switch
externally supplied 11 to 240 VAC. The internal logic
signals are isolated from the external outputs to 2100
VDC.
Features
• 8 or 16 AC output points
• Replaces Siemens® 505-4608, -4616, -4808, and
-2816
• 3000 VDC group-to-group isolation
• 2100 VDC channel-to-backplane isolation
• Isolation in groups of four (16pt. login) or in groups
of two (8pt. login)
• Wide 11-240 VAC output range
• 2.0 Amps per output
• 16 Amps total module output
• Individually fused outputs
• Sourcing outputs
• Single-wide module

2598 8/16-Point
AC Discrete Output Module
8/16 Point Configuration Explanation
The 2598 was designed to be primarily a 16pt module. However, in order to provide maximum flexibility for the user, it may
also be configured as an 8 point module. Some details are listed below to help the user better understand the jumper
settings and PCB labeling discrepancies for the 8 point setting.
Grouping Configuration
The 2598 is shipped to allow four channels to be grouped and share a common field user power, thereby allowing a differ-
ent user power supply voltage to be used by each grouping. Jumpers J2, J4, J5, and J6 come set in the “8 Common” selec-
tion from the factory and should not be altered for proper module operaton. In 16 point configuration this setting allows for
4 points per common operation. In 8 point configuration this setting allows for 2 points per common.
For example, Channels 1-4 will share a common user power and Channels 5-8 will share another common user power. In
this example each group of four channels is isolated from the other group of four channels. Because each group of four is
isolated, the user may change the supply voltage for each group. So in this example, Channels 1 thru 4 could be
120VAC outputs and Channels 5 thru 8 could be 240VAC outputs.
8 Point Mode: Move jumper in “Login” box to location JP3 to choose 8pt mode. Ensure the Isolation jumpers J2,4,5,
& 6 are in ‘8 Common’ positions to correspond to the Siemens® counterpart 8 point modules (2 inputs/ common). Al-
so, note that many of the printed channels (CH 1-CH 32) on the PC board are no longer valid, nor are the front panel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. (You may find it helpful to utilize the appropriate 8 pt. connector labels shipped with the product.) If 8
Point is enabled, the following table’s 8pt. row is the new correlation of PC board printing and front panel label’s LED
area printing. For example, in 8 Point Login Configuration, the board marking for channel 10 (CH 10) would be the input
channel 6. Likewise, the PC board marking for CH 13 would correlate to input channel 7.
