 Product Description

Input Module, Non-Isolated, Thermocouple / RTD / Mv 1794 FLEX I/O

 Warranty Information

All Surplus and Refurbished products come with a 1-Year Automation Webstore Warranty.

 Product Overview

The 1794-IRT8 is an electronic module that is used for Temperature measurements compatible for use with Resistance-Temperature Detector (RTD), Thermocouple and mV source inputs. It features high-speed and high accuracy linearization and measurement thus, applicable to processes that require fast update and low reading deviation.

This module has input resolution of 14 bits. It can be used to interface with RTD sensors such as 100 ? Pt ? = 0.00385 Euro (-200…+870 °C) 100 ? Pt ? = 0.003916 U.S. (-200…+630 °C) 200 ? Pt ? = 0.00385 Euro (-200…+630 °C) 500 ? Pt ? = 0.00385 U.S. (-200…+630 °C) 100 ? Nickel ? = 0.00618 (-60…+250 °C) 120 ? Nickel ? = 0.00672 (-60…+250 °C) 200 ? Nickel ? = 0.00618 (-60…+250 °C) 500 ? Nickel ? = 0.00618 (-60…+250 °C) 10 ? Copper ? = 0.00427 (-200…+260 °C).

This module also supports Thermocouple sensors such as Type B: 300…1800 °C (572…3272 °F) Type E: -270…1000 °C (-454…1832 °F) Type J: -210…1200 °C (-346…2192 °F) Type K: -270…1372 °C (-454…2502 °F) Type TXK/XK (L):-200…800 °C (-328…1472 °F) Type N: -270…1300 °C (-454…2372 °F) Type R: -50…1768 °C (-58…3214 °F) Type S: -50…1768 °C (-58…3214 °F) Type T: -270…400 °C (-454…752 °F).

Compatible applications for this module are Temperature processes. As this is a Programmable Logic Controller (PLC) module, proper configuration of the analog channel must be checked. In PLC terms, the Thermocouple Type refers to the linearizer. So for a Thermocouple Type K, the linearizer to be activated in the analog module shall be Type K also.VIIIVThe 1794-IRT8 is a Flex IO Eight (8) channel RTD / Thermocouple input module. This module features high=speed and high accuracy Temperature measurement. It accepts Thermocouple inputs, 2, 3 and 4 wire RTDs as well as mV source inputs.
