【英文介绍】
The 1794-IRT8 module is an Allen-Bradley FLEX I/O millivolt, thermocouple, and RTD module. In the FLEX I/O system, the 1794-IRT8 module is connected to the terminal base and power adapter.
Allen-Bradley 1794-IRT8 comes with 2 cold end compensators. The cold-end compensator improves the precision of the module in thermocouple mode. The 1794-IRT8 module has a rated voltage of 24 volts DC and 8 analog inputs. It can be connected to up to 8 RTD or thermocouple inputs. The front panel of the 1794-IRT8 module has a nameplate identifying the module, a user customizable detachable label, a key switch position indicator and an LED status indicator.
The RTD sensors compatible with this module are 2-wire, 3-wire and 4-wire RTDS, such as 100? Platinum? = 0.00385 euros -200... 870 degrees Celsius (-328... 1598 degrees Fahrenheit) 200? Platinum? = 0.00385 euros -200... 400 degrees Celsius (-328... 752 °F) 100? Platinum? = 0.003916 United States -200... 630 °C (-328... 1166 degrees Fahrenheit) 100? Platinum? = 0.003916 United States -200... 400 degrees Celsius (-328... 752 °F) 100? Nickel-60... 250 °C (-76... 482 degrees Fahrenheit) 200? Nickel-60... 200 °C (-76... 362) Fahrenheit) 120? Nickel-80... 320 °C (-112... 608 °F) 10? Copper -200... 260 °C (-328... 470°F). The thermocouple sensors supported by this module are B, E, J, K, TXK/XK (L), N, R, S and T thermocouples.
The module has a resolution of 14 bits and has optional data formats such as °C (hidden decimal point XXX.X), °F (hidden decimal point XXX.X), °K (hidden decimal point XXX.X) -32767... 32767 0... 65535 0... 5000 ohm pattern (implied decimal point XXX.X) -4000... +10000 millivolt mode (implied decimal point XXX.XX).
The 1794-IRT8 features embedded diagnostics, including open circuit detection, where module readings are upgraded or default to maximum values in RTD and thermocouple modes. It also has an open input detection time for 2 scans and an overvoltage capability of 15V DC continuously at 25 °C. When wiring signals, the recommended wires are TC manufacturer specified thermocouple wires and Belden 8761 for millivolt signals.
