GE Fanuc Emerson IC694ALG223DB 16-Channel Analog Input Module

The GE Fanuc / Emerson IC694ALG223DB is a high-performance analog input module designed for PACSystems RX3i platforms. It converts industrial current signals into stable digital values, supporting transmitters used for flow, temperature, pressure, and other critical measurements. Moreover, the module offers enhanced 4–20 mA capability, allowing engineers to detect open-wire faults before they affect plant operations. Therefore, it provides reliable data acquisition for demanding process and factory automation tasks.

Its hot-swappable construction keeps production running because technicians can replace the module without shutting down the system. In addition, the module includes extensive certifications, making it suitable for hazardous and marine applications where compliance is essential. For instance, offshore facilities and chemical plants often choose this model for its diagnostic depth and long-term stability.
