The Allen-Bradley 1771-IVN PLC 5 Digital DC Input Module is designed to efficiently convert DC signals from user devices into logic levels required by the processor, directly affecting the corresponding bits within the PLC data table. This series C module, which supports both and 1-slot I/O addressing, features a compact, modular design that is easy to integrate, aided by the 1771-WN wiring arm for seamless module replacement without disconnecting wiring. With 32 inputs divided into four sets of eight and an operational voltage range of 10-30V DC, it offers reliable performance with a signal delay of 6ms, ample optoelectrical isolation for protection against electrical transients, and input filtering to minimize electrical noise, making it ideal for applications involving Sink DC input signal termination.
