Allen-Bradley 2085-IRT4 Micro800 Thermocouple/RTD Input Module

Product overview

The Allen-Bradley 2085-IRT4 is a 4-channel temperature input module with 16-bit resolution, where each channel is set for its own sensor. It takes thermocouple types B, C, E, J, K, TXK/XK (L), N, R, S and T; 100 and 200 Ω platinum RTDs (Euro and U.S. curves), 100 and 200 Ω nickel 618, 120 Ω nickel 672 and 10 Ω copper 427 RTDs; plus 0…100 mV and 0…500 Ω inputs. Bus current draw is 160 mA at 5V DC and 50 mA at 24V DC. It extends Micro850 and Micro870 controllers, is an open-style module rated for -20…+65 °C operating, and the last module in the system takes a 2085-ECR bus terminator.
