Allen Bradley 1746-ITB16 SLC 500 Fast Input Module

Product Overview

The Allen Bradley 1746-ITB16 is a high-speed discrete sinking input module built for the SLC 500 platform. With 16 input channels, it efficiently handles rapid switching signals and supports applications requiring pulse frequencies up to 2 kHz when paired with compatible encoders such as the 845D Absolute Gray Code Encoder.

Engineers prefer the 1746-ITB16 for its 24VDC nominal input voltage, sink wiring configuration, and minimal signal delay of 0.3 ms ON and 0.5 ms OFF, ensuring precise data capture in automation tasks. Its compact form and 0.56 lbs weight simplify installation while offering long-term durability.

When combined with SLC 5/03 or SLC 5/04 controllers, the module works seamlessly with Discrete Input Interrupt (DII) instructions, allowing efficient processing of fast gray code encoder signals.
