Product Overview：GE 201CI-1
The GE 201CI-1 is a high-performance Digital Input Module designed for industrial automation systems, serving as a critical interface between field devices and programmable logic controllers (PLCs). As part of GE’s VersaMax series—a versatile platform renowned for reliability in harsh industrial environments—the 201CI-1 enables seamless acquisition of discrete input signals from sensors, switches, and relays. This module supports 16 isolated channels, each capable of handling 24 V DC signals, making it ideal for applications requiring robust signal conditioning and noise immunity in manufacturing, energy, and process control sectors.
Engineered to enhance system responsiveness, the GE 201CI-1 features galvanic isolation (2.5 kV RMS) to protect against voltage surges and ground loops, ensuring accurate data transmission even in high-electromagnetic interference (EMI) environments. Its compact design (100 mm × 110 mm × 50 mm) and DIN rail mounting facilitate easy integration into control panels, while compatibility with GE’s VersaMax Micro and VersaMax I/O systems allows scalable expansion of input/output capabilities. By converting physical states (e.g., open/closed contacts) into digital signals for PLC processing, the 201CI-1 plays a pivotal role in real-time monitoring, safety interlocking, and process automation workflows.
In industrial ecosystems, the GE 201CI-1 bridges the gap between field instrumentation and higher-level control systems, enabling precise tracking of machine status, valve positions, and conveyor operations. Its diagnostic LEDs provide real-time feedback on signal integrity and module health, reducing troubleshooting time and minimizing unplanned downtime. Whether deployed in standalone machines or complex distributed control systems, this module delivers consistent performance, making it a trusted choice for industries prioritizing reliability and ease of integration.
