sixteen TTL or CMOS compatible outputs to the CTI

2500 SeriesTM or Simatic® 505 I/O base. The

module is designed to respond to standard output

instructions. With the 2595. the PLC is capable of

providing signals to a variety of field devices

including lab instrumentation, BCD message

displays, video terminals, board level devices, and

low current annunciator panels. With an external pull

up resistor, the 2595 can interface to 24 VDC control

systems and other instrumentation. The module can

drive up to 16 CMOS or TTL loads per output.

Description

The  2590-EF and 2591-EF 16-Point Discrete Output Modules provide sixteen

isolated outputs from the CTI 2500 SeriesTM or Simatic®  505 I/O base with

front panel accessible fuses. The modules use solid-state output circuits to

switch on or off external devices such as pilot lamps, motor starters,

or solenoids. The  2590-EF is designed to switch externally supplied 20

to 132 VAC and the 2591-EF is designed to switch externally supplied 11 to

146 VDC.

For both modules, the internal logic signals are isolated from the external

outputs to 1500 VDC.

Features

•Supports sourcing and sinking applications

•Front panel accessible fuses for easier maintenance

•2A per output 2590-EF (no derating) 1.5 A per output 2591-EF (no derating)

•Blown fuse reporting directly to PLC for each channel

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

• Isolated 1500 VDC channel-to-channel 2590-EF

Module Configuration

The 2590-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 2590-A module is inserted in slot

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

“Y1”. The 2590-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.

Voltage Range Selection Jumpers

The 2589-B will handle a wide range of AC and DC signals,

and has incorporated the ability to select either 12V/24V, 48V,

110V, or 220V on a per channel basis using jumper selection.

The selections are made individually for each of the 32

channels using jumpers. However, the same voltage range

must be selected for all channels in the same group. The

operating ranges are as follows:
