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

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.

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.
