CTI 2501 8in/4out Analog Module

Description

The 2501 module provides an eight channel analog input and four channel

analog output design in a compact, single-wide module to fit in the CTI 2500 SeriesTM

or Simatic® 505 Series I/O base. It is useful in applications such as machine control,

loop temperature control and weighing systems. 

The 2501 replaces Siemens® 505- 7012 and 505-7016 modules,

except in applications which use the built-in scaling feature.

Features

• CTI 2500 SeriesTM or Simatic® 505 base format

• Fast 6 mSec update time for all channels

• Selectable input/output or input only operating mode

• Bipolar or unipolar inputs per channel

• Inputs: 1500VDC channel-to-PLC isolation

• Outputs:

• 1500V channel-to-channel isolation

• Voltage and current outputs available simultaneously

• Bipolar or unipolar outputs per channel
