CTI 2559-TC 8-Channel Thermocouple Input Module

Description

The 2559-TC is a high-speed 8-point thermocouple

input module designed to translate

millivolt level signals from the thermocouple

element into a scaled temperature value in a CTI

2500 Series or Simatic® 505 I/O base.

Features

• CTI 2500 Series or Simatic® 505 base format

• Replaces Siemens® 505-7028 with no rewiring

• 1500V channel-to-PLC backplane isolation

• Fast 9 mSec update time all channels

• Microprocessor self-diagnostics

• Supports J, K, T, E, R, S, & N thermocouples and millivolt inputs

• No CJC calibration needed
