Allen-Bradley 1746-IB32 SER D Digital Input Module

The 1746-IB32 module operates within a voltage range of 15 to 30V DC at 50°C (122°F) or 15 to 26.4V DC at 60°C (140°F). It features 32 input points organized into four groups of eight, each group sharing a common terminal. This configuration allows for efficient wiring and integration of multiple input devices. The module consumes 50 mA of current from the backplane at 5V DC and provides isolation from the backplane up to 1500V AC for one minute, ensuring reliable operation in industrial environments. Series D modules are not fused, which differs from earlier series that included non-replaceable fuses rated at 2.5A per common.
