The Allen-Bradley 1771-IBD is a discrete input that is part of the 1771 Product family. This module is a single slot width component that mainly features Sixteen (16) 10-30VDC discrete inputs channels. It is mounted to any of the available 1771 chassis except for 1771-A1, 1771-A2 and 1771-A4.
Discrete input modules such as 1771-IBD are typically used to interface field signaling devices such as switches, sensors, auxiliary contacts that represent the state of the process. It is especially compatible for use with ON/OFF; 1 or 0 or binary operating devices.
The 1771-IBD comes with Eighteen (18) LED status indicators that provides information regarding the module status and the signal status present at each input channel of the module. It also comes with a Field Wiring Arm with compatible replacement part number of 1771-WH. Field Wiring Arms are used to provide modular wiring method as they can be removed from the module when terminating signals. Additionally, they contribute to ease of maintenance as they can be removed and installed to compatible modules without the need of disconnecting the attached wires.
