PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-IB32 is a FlexBus Input Module in the FLEX I/O platform. This module features 32 current sinking DC inputs for industrial control systems. The unit operates with a nominal input voltage of 24V DC. It accepts a minimum on-state voltage of 19.2V DC and a maximum of 31.2V DC. The nominal on-state current is 4.1 mA at 24V DC.
The module draws a Flexbus current of 30 mA at 5V DC backplane power. Maximum power dissipation reaches 6.0 W when operating at 31.2V DC. Off-state limits require voltage below 5V DC and current below 1.5 mA. The nominal input impedance measures 22.2 kiloohms across active circuits. The physical assembly weighs approximately 0.56 lbs or 0.26 kg.
