2500-TAP, 2501

2500-TAP RS485 Network Tap

The 2500-TAP Remote I/O Network Tap is specially design

for attaching trunkline and dropline sections to create 2500

Series® remote I/O networks. These taps use an

impedance-controlled design for highest noise immunity and

include built-in termination resistance which can be easily

switched in- or out- of the circuit using a toggle switch.

They also include an electrical noise bleed path to chassis

ground which can improve the noise immunity of your

network.

Features:

 Dust and water resistant installation

 Impedance controlled design

 Built-in terminating resistance

 Electrical noise bleed system for improved noise immunity

2501 8in/4out Analog Module

The 2501 module provides eight channels of analog input

and four channels of analog output in a compact, single-

wide module to fit in the CTI 2500 Series® or Simatic®

505® I/O base.

Features:

 Replaces Siemens® 505-7012 and 505-7016 with no

rewiring

 Fast 6mSec update time for all channels

 Selectable input/output or input-only operating modes

 Bipolar or unipolar inputs per channel

 Inputs: 1500V channel-to-backplane isolation

 Outputs:

 1500V channel-to-channel isolation

 Voltage and current outputs available simultaneously

 Bipolar or unipolar outputs per channel
