Product Overview
The Emerson 8121-DI-DC-05 Digital Input Module is engineered for reliable signal acquisition in harsh industrial environments. With 16 non-isolated digital input channels, it supports 24VDC logic levels and is ideal for monitoring switches, sensors, and contact closures across a wide range of applications.
Moreover, the module offers selectable input filtering from 2 to 512 milliseconds, allowing users to optimize response time and noise immunity based on system requirements. In addition, it includes an optional pulse counting feature, enabling accurate tracking of high-speed digital events such as flowmeter pulses or encoder signals.
The 8121-DI-DC-05 is part of the PAC8000 Remote I/O family, known for its modularity, environmental resilience, and compatibility with hazardous area installations. Therefore, it is a trusted solution for distributed control systems in oil & gas, power, and manufacturing sectors.
