Allen-Bradley 1756-IB16 ControlLogix 24V DC Digital Input Module | 16 Point

Description

【Product Overview】

The Allen-Bradley 1756-IB16 is a high-reliability 16-point Digital Input Module designed for the ControlLogix automation platform.

As a core component of the 1756 I/O family, this module interfaces with various field devices—such as push buttons, limit switches, and proximity sensors—converting 24V DC sink/source signals into logic states for the ControlLogix processor. The Series A version is renowned for its rugged hardware design and long-term stability in harsh industrial environments. Whether you are maintaining a legacy manufacturing cell or replacing a critical failed unit in a 24/7 production line, the 1756-IB16 provides the precise signal detection and optical isolation required to protect your control architecture and ensure continuous uptime.

【Technical Specifications】
