Description

The 2597 8/16/32-Point DC Discrete Output Module

provides eight, sixteen, or thirty-two sourcing fused

outputs 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 2597 is

designed to switch externally supplied 11-125 VDC.

The internal logic signals are isolated from the

external outputs to 2100 VDC.

• Individually sourcing fused outputs

32-Point Mode: 4 Common Configuration

The user may configure the module to allow four 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. J5. and J6 are used to configure this selection.

For example, if the user places the J2 jumper in the 4 Common position, 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 also change the supply voltage for each group. So,

in this example, Channels 1-4 could be 24VDC outputs and Channels 5-8 could be 60VDC outputs. Furthermore, the user may

select a different configuration for J4. J5. or J6. allowing for further combinations of four or eight channels that share a common.

32-Point Mode: 8 Common Configuration

The module can also be configured so that eight channels share a common user power. The same jumpers mentioned above, J2. J4.

J5. and J6. are used for this selection.

In this example, if jumper J2 was placed in the 8 Common position, then Channels 1-8 would share the same common and only

one supply voltage could be used on these eight channels. With this selection each group of eight channels is isolated from the oth

er, allowing up to four different supply voltages to be accommodated per module.

Login 8/16/32 Point Configuration Explanation

The 2597 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 are listed 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 JP2 to choose 16pt mode. Ensure the Isolation jumpers J2.4.5. & 6 are in

‘8 Common’ positions to correspond to the Siemens® counter- part 16 point modules (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. (You may find it helpful to utilize the appropriate 16 pt. connector labels shipped with the product.) If 16 Point is enabled, the

following table’s 16pt. row is the new correlation of PC board printing and front panel label’s LED area 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.

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® counter- part 8 point modules (2 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. (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 4. Like- wise, the PC board mark

ing for CH 25 would correlate to input channel 7.
