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.

In the example Figure 2. the 16-point TTL input module is inserted

in slot 1 in I/O base 0 and configured as a DISCRETE module using

JP1. In the example below  data appears as 16 “X” locations starting

at “X1”. For your particular module, look in the chart for the number

corresponding to the slot occupied by the module. If bit locations

appear on this line, then the module is registered in the PLC

memory and the module is ready for operation.
