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
