Description

The 2530 8-Point Relay Contact Module provides eight isolated “Form C” relay outputs

for the CTI 2500 Series® or Simatic® 505 I/O base. The 2530 is designed for high

current applications such as switching motor starters.

The 2530 is also designed for 125 VDC (nominal) low level current applications. 

This module is especially suited for applications in power utility stations.

Features

• 8 individually isolated “Form C” relay outputs

• Up to 4 amps per output

• 1500V channel-to-PLC backplane isolation

• Switches 125 VDC (ideal for power utility substation applications)

• Single-wide module

• CTI 2500 Series® base format

Channel Configuration Explanation

The 2598-8 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 2598-8 channels.

See 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 ‘CH 10’ on the PCB.

Grouping Configuration

The 2598-8 is shipped to allow two 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. J6. and J8 come set in the “8 common” selection from the

factory and should not be altered for proper module operaton. 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 two channels is isolated

from the other group of two channels. Be-cause each group of two is isolated,

the user may also change the supply voltage for each group.

So, in this example, Chan- nels 1-2 could be 240VAC outputs and Channels 3-4 could

be 120VAC outputs.
