The Allen-Bradley 1771-ID16 is a versatile 120V AC/DC isolated input module, strategically designed for integration with PLC-5 Processors within the 1771 Digital AC/DC Input Modules suite. Enhanced by customer-selectable input filtering, the 1771-ID16 effectively mitigates voltage transients from contact bounce or electrical noise, thereby improving power quality, enhancing longevity, and reducing downtime related to electrical issues. Featuring a factory-set filter time of 9ms, it provides efficient signal processing with typical delays of 9 or 18ms for AC input transitions and 0.57ms for DC inputs. Compatible with the 1771-A1B or 1771-A4B I/O chassis, the module is well-suited for multiphase applications and can be effortlessly connected via a 40-terminal field wiring arm, ensuring seamless integration without wire disconnection during installation or maintenance.
