Product Overview
The 1756-IM16I is an Allen-Bradley ControlLogix module providing sixteen individually isolated 240 VAC digital inputs, operating within 159…265 VAC (47…63 Hz). It occupies one slot in a ControlLogix rack and isolates each input channel, enabling reliable detection of AC field signals. Typical in industrial control systems, it is used for monitoring high-voltage sensors or switches in process industries, discrete machine control, and applications requiring AC signal interfacing with electrical isolation.
