Allen-Bradley 1756-IF8 ControlLogix 8-Channel Analog Input Module
Allen-Bradley 1756-IF8 is a ControlLogix analog input module with 8 single-ended, 4 differential or 2 high-speed differential inputs.
Overview
The module accepts 0-20 mA current or -10 to 10V, 0 to 10V and 0 to 5V voltage ranges, converting via the sigma-delta method. Onboard data alarming and real-time channel sampling are supported. Input impedance is 1 megaohm in voltage mode and 249 ohms in current mode. It draws 150 mA at 5.1V DC and 40 mA at 24V DC (1.73 W backplane power) with 1.73 W dissipation in voltage mode or 2.33 W in current mode.
