CTI 2595 - 16-point TTL/Word Output Module

Description

The 2595 16-Point TTL Output Module provides

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.

Word and Discrete Mode

The 2595 may operate as a 16 Bit Word Output Module or as a 16

Discrete Output Module. By setting JP1 in Word Mode and using Work

shop to configure I/O the 2585 will look like a standard WX input mod

ule; for example WY1-WY8.

NOTE: The 2595 will be mapped as the first WY address (i.e. WY1). 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 output module is inserted in

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

using JP1. In the example below  data appears as 16 "Y" locations start

ing at "Y1". For your particular module, look in the chart for the num

ber 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.
