CTI 2585 16-point TTL Input Module

Description

The 2585 16-Point TTL Input Module accepts sixteen

TTL driven inputs to the CTI 2500 SeriesTM or

Simatic® 505 Series I/O base. The inputs are

isolated channel-to-channel.

The 2585 has an input voltage range from 2.6 to 28

VDC; therefore, the inputs may be driven by CMOS

and open collector transistor devices.

Features

• CTI 2500 Series and Simatic 505 base format

• 500 V channel-to-channel isolation

• 1500 V channel-to-PLC backplane isolation

Word and Discrete Mode

The 2585 may operate as a 16 Bit Word Input Module or as a 16 Dis

crete Input Module. By setting JP1 in Word Mode and using Workshop

to configure I/O the 2585 will look like a standard WX input module; for

example WX1-WX8.

NOTE: The 2585 will be mapped as the first WX address (i.e. WX1). In

Word Mode Channel 1 corresponds to bit 16 or LSB and Channel 16

corresponds to Bit 1 or MSB.

Note:

If the address line is blank or erroneous, re

check the module to ensure that it is firmly

seated in the slots. Generate the PLC I/O

configuration chart again. If the address

line is still incorrect, contact your local dis

tributor or CTI at 1-800-537-8398 for fur

ther assistance.

Changing Operating Modes

Any time the operating mode of the 2585 is

changed with JP1. the module must be con

figured in the PLC. Failure to do so may

cause unpredictable operation due to the

fact that the PLC uses different methods of

addressing discrete modules from word

modules.
