Brand: Allen Bradley Description: Digital Input Module Condition: New Warranty: 1 year Inventory Qty: 5 Payment term: T/T Shipping Port: ShenZhen Allen Bradley 1756-IB16 is a 16-channel DC digital input module. Its main function is to receive discrete signals (such as 24V DC switch quantity) from buttons, switches, sensors and other devices, and convert the signals into logical states that can be recognized by the controller. It is suitable for control systems with high reliability requirements.

Functional features and principles
Optoelectronic isolation: Each channel is independently isolated to prevent external interference or high voltage from damaging the controller.
Programmable configuration: Allen Bradley 1756-IB16 sets input filter time through RSLogix 5000 (V20.01 or higher) to optimize noise immunity.
Hot plugging and unplugging: Allen Bradley 1756-IB16 can replace modules without powering off, reducing downtime.
Modular design: plug and play, compatible with ControlLogix rack, supports local or distributed I/O architecture.
Allen Bradley 1756-IB16 supports optical isolation and hot plugging and unplugging functions, which can enhance system safety and simplify maintenance processes, becoming a core component for discrete signal acquisition.
