Product Overview
The 8125-DI-DC is a high-density digital input module from GE’s PAC8000 series, designed for industrial I/O applications. It provides 32 discrete input channels, ideal for monitoring switches, proximity detectors, and other digital field devices. The module draws power directly from the PAC8000 backplane, simplifying installation while maintaining robust performance.
Built-in line fault detection and selectable response times ensure accurate diagnostics and reliable operation in harsh environments. Pulse counting and latching features allow advanced monitoring of fast digital signals, making the 8125-DI-DC suitable for demanding process control systems.
Functional Description
The 8125-DI-DC module provides source-type digital inputs compatible with dry contact switches and proximity detectors. It features high-speed input sampling (8 kHz) and advanced fault detection, including open and short-circuit monitoring. Channel-to-railbus isolation enhances safety and signal integrity. Designed for DIN rail mounting, this module integrates seamlessly into PAC8000 modular I/O systems.
