Description

2500 Series®  PLC System

Product Bulletin

The 2591-A 16-point Isolated Discrete Output Module

provides sixteen discrete isolated outputs from the CTI

2500 Series®  or Simatic® 505 I/O base. The module

uses solid- state output circuits to switch on or off exter

nal devices such as pilot lamps, motor starters, or sole

noids. The 2591-A is designed to switch externally sup

plied 11 to 146 VDC. The internal logic signals are iso

lated from the external outputs to 1500 VDC.

Features

• CTI 2500 Series® or Simatic® 505 I/O base format

• 1.5 Amps per output (no derating)

• Isolated 1500 VDC channel-to-channel

• Blown fuse reporting (per channel) to the PLC

• Blown fuse indicator

• Logs in as a 16Y or 16X/16Y (jumper selectable)

• Individual fuse for each output channel

• Single-wide module

The 2591-A is capable of logging in as a 16Y or a 16X/16y.

Changing the addressing of the module is done by moving a

jumper located near the rear backplane connector as shown in

Figure 2 below. In Figure 2. the 2591-A module is inserted in slot

1 in the I/O base 0. Data appears as 16 "Y" locations starting at

"Y1". The 2591-A ships with a login of 16Y. In this configura

tion blown fuse reporting is disabled. By moving the jumper to

the REPORTS 16X INPUTS the module logs in as a 16X/16Y.

The X addresses are used to report the Blown Fuse Indication

and the 16Y addresses are used as any other normal output

would be used.
