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.
