1794-IRT8 Allen-Bradley Flex I/O combination module

The 1794-IRT8 module is an Allen-Bradley FLEX I/O millivolt, thermocouple, and RTD module. In a FLEX I/O system, the 1794-IRT8 module is connected to a terminal base and a power adapter.

The Allen-Bradley 1794-IRT8 is shipped with 2 cold junction compensators. This cold junction compensator increases the accuracy of the module for Thermocouple mode. 1794-IRT8 module has a nominal voltage rating of 24 Volts DC and 8 analog inputs. It can connect to up to 8 RTD or thermocouple inputs. The front panel of the 1794-IRT8 module has a nameplate that identifies the module, a removable label that the users can customize, a keyswitch position indicator, and LED status indicators.

Compatible RTD sensors for this module are 2-wire, 3-wire and 4-wire RTDs such as 100 ? Pt ? = 0.00385 Euro -200…870 °C (-328…1598 °F) 200 ? Pt ? = 0.00385 Euro -200…400 °C (-328…752 °F) 100 ? Pt ? = 0.003916 U.S. -200…630 °C (-328…1166 °F) 100 ? Pt ? = 0.003916 U.S. -200…400 °C (-328…752 °F) 100 ? Nickel -60…250 °C (-76…482 °F) 200 ? Nickel -60…200 °C (-76…362) °F) 120 ? Nickel -80…320 °C (-112…608 °F) 10 ? Copper -200…260 °C (-328…470 °F). While supported Thermocouple sensors by this module are Thermocouple Type B, E, J, K, TXK/XK(L), N, R, S, and T.
