CTI   2598 8/16-Point AC Output Module

2598 8/16-Point AC Output Module

The 2598 provides 8 or 16 11-240 VAC outputs from the CTI 2500 Series® or Simatic® 505 I/O base. The solid-state output circuits can be used to switch on or off external devices such as pilot lamps, motor starters, or solenoids.

Features

2598 replaces Siemens® 505-4608. 4616. 4808. 4816

Individually fused sourcing outputs

Isolation in groups of 2 or 4 (depending on configuration)

Wide 11-240 VAC output range

2.0 Amps per output

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so, note that many of the printed channels (CH 1-CH 32) on the PC board are no longer valid, nor are the front panel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.
