2085-IRT4 | Allen-Bradley Micro 850 Analog Input Module, 4-Pt, Thermocouple/RTD

Description 

The 2085-IRT4 input module is an expansion input module from the Allen-Bradley/Rockwell Automation Micro 850 series. It is a temperature type of expansion input module. The 2085-IRT4 expansion input module has 4 thermocouple inputs. There is isolation between the field side wiring and the controller that the input module operates with, but there is no isolation between the 4 inputs. The 2085-IRT4 expansion input module provides noise rejection for its input signals through a digital filter.

Information About 2085-IRT4

The Allen-Bradley 2085-IRT4 is a Micro850 series isolated 4-channel analog input module. This specialty module comes with a Thermocouple/RTD interface, specifically an isolated Thermocouple and 16-bit RTD. The thermocouple types present in this module are the B, C, E, J, K, TXK/XK (L), N, R, S, and T types, while the RTD types are the 100 Ω Pt α = 0.00385 Euro, the 200 Ω Pt α = 0.00385 Euro, the 100 Ω Pt α = 0.003916 U.S, the 200 Ω Pt α = 0.003916 U.S., the 100 Ω Nickel 618, the 200 Ω Nickel 618, the 120 Ω Nickel 672, and the 10 Ω Copper 427. It also has an Ohm input of 0-500 Ω, as well as a mV range of 0-100 mV. Its accuracy for RTD inputs ranges from +/- 0.2 to +/- 0.6 oC, while for Thermocouple inputs it is +/- 0.5 to +/- 3 oC. The typical channel update time of the 2085-IRT4 module is 12-500 ms per enabled channel. It also has an input impedance greater than 10 M Ω and a continuous isolation voltage of 50V from channel to system and is a reinforced isolation type. Its total power dissipation is 2 W and maximum bus current draws are 5V DC at 160 mA and 24V DC at 50 mA.

The maximum surrounding air temperature of this drive is 65 oC, the operating temperature is from -20-65 oC, and the storage temperature is -40-85 ËšC. It also has a non-condensing relative humidity of 5-95%. This drive has an operating shock of 25 g, a non-operating shock of 25 g when panel mounted or 35 g when DIN rail mounted, and an operating vibration of 2 g at 10-500 Hz. Present on this drive is 1 green health indicator, and the drive has an IP20 enclosure rating. The approximate shipping weight of this drive is 220 g and its measurements are 1.75 x 3.54 x 3.42 inches.
