CTI 2596-8 8-point DC Discrete Output Module

Description

The 2596-8 8 Point DC Discrete Output Module

provides eight 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 2596-8 is designed to switch

externally supplied 11-125 VDC.

Login 8/16 Point Configuration Explanation

The 2596-8 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 2596-8 channels.

See the 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 ‘CH10’ on the PCB.

Grouping Configuration

The 2596-8. two channles are grouped together

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 set in the “8 Common” selection from

the factory and, for proper module operation,

should not be altered. This setting allows for 2

points per common operation.

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 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 1-2 could be 24VDC outputs and

Channels 3-4 could be 60VDC outputs.
