Product Description
Allen-Bradley 1756-IB16I A DC Isolated Input Module
The Allen-Bradley 1756-IB16I Series A is a highly reliable 16-point isolated DC input module designed for the industry-leading ControlLogix programmable logic controller (PLC) platform. Featuring 16 individually isolated inputs, this module provides excellent channel-to-channel isolation, making it the perfect solution for applications requiring strict electrical noise immunity and independent grounding. It operates efficiently within a voltage range of 10 to 30 VDC (at 10mA) and draws minimal backplane current (100mA @ 5.1VDC and 3mA @ 24VDC). Engineered for rugged industrial environments, the 1756-IB16I operates safely in ambient temperatures up to 60°C and carries comprehensive hazardous location certifications, including UL, CE, CSA, FM Class I Division 2, IECEx, and ATEX.
