Product Overview

The 1771-IBD is a discrete DC input module from the Allen-Bradley PLC-5 1771 family. It provides sixteen 10-30 V DC sink-type input channels in a single slot module mounted in a 1771 I/O chassis (excluding 1771-A1, A2, A4 models). Its primary role in a control system is to interface field devices-such as switches, sensors, or auxiliary contacts-to the PLC logic table, translating on/off signals into digital inputs. It is often used in machine control, process monitoring, and industrial automation systems where multiple DC input points are required and the PLC-5 platform is in use. Part number 1771-IBD.

Best Suited For

  • PLC-5 systems requiring 16 DC input points
  • Sensing discrete field devices (switches, sensors) in industrial control
  • Applications needing sink-configured digital inputs
  • Replacement or repair in legacy PLC-5 installations
