The Allen-Bradley 1771-IBD is an advanced discrete input module from the 1771 product family, offering sixteen 10-30VDC input channels designed for efficient interfacing with field signaling devices like switches and sensors. Suitable for ON/OFF binary operations, this module provides enhanced usability with its eighteen LED status indicators, which deliver immediate feedback on module and input signal status. Installed in a compatible 1771 chassis, excluding the 1771-A1, A2, and A4 options, it includes a 1771-WH Field Wiring Arm for streamlined connections, offering quick detachment for maintenance without unwiring. Designed with precise signal delay of 1.3ms and robust power specifications, including a maximum power dissipation of 6W and thermal dissipation of 20.3 BTU/hr, the 1771-IBD ensures optimal performance and reliability in various industrial applications.
