PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-IB16 is a 16-point digital DC input module for the SLC 500 controller platform. This module operates within a nominal 24V DC voltage category with an operating range of 10V to 30V DC. It provides current sinking inputs designed to interface with sourcing field devices in automated control applications.
The module draws 0.05 A backplane current at 5V DC and 0 A at 24V DC. Heat dissipation equals 0.2 W per point, with minimum dissipation of 0.425 W and total dissipation reaching 3.6 W. A removable terminal block simplifies maintenance by allowing replacement without rewiring individual connections. Maximum signal delay is 8 ms for on and off transitions during field signal acquisition.
