GE Fanuc IC200ALG230D Analog Input 4CH ±10V 4-20mA

GE Fanuc IC200ALG230D VersaMax 4-Channel 12-Bit Analog Input Module

The IC200ALG230D (Model: IC200ALG230D) is a versatile analog input module from the GE Fanuc (Emerson) VersaMax™ series. It is designed to interface with 4 single-ended analog channels, converting bipolar or unipolar signals into 12-bit digital values for the PLC CPU. This module is an essential component for distributed I/O systems, providing high-speed data acquisition with an update rate as fast as 0.4 ms. Its compact, rail-mounted design and optical isolation make it suitable for harsh industrial environments where signal integrity and space efficiency are paramount.

Deterministic Signal Processing and Isolation

The IC200ALG230D is engineered for high-speed process loops. With an internal update rate of 0.4 ms, it allows the PLC to react almost instantaneously to changes in pressure, flow, or temperature. To ensure the safety of the central control rack, the IC200ALG230D (Model: IC200ALG230D) utilizes 1500 VAC optical isolation. This barrier prevents high-voltage field transients from damaging the PLC backplane or other modules in the rack, providing the "Trustworthiness" required for mission-critical industrial automation.
