Description

Overview

The IC200ALG430 from GE Fanuc Emerson VersaMax series is a compact analog mixed I/O module designed for 4–20 mA current loop signal acquisition and output control. It integrates both input and output functionality in a single-slot module, reducing rack space while maintaining high signal integrity.

It is engineered for process automation systems where stable analog current transmission is required, such as flow, pressure, level measurement, and actuator positioning.

Functional Design

• 4 differential analog input channels (4–20 mA)

• 2 single-ended analog output channels (4–20 mA)

• 12-bit analog-to-digital and digital-to-analog conversion

• Independent input/output signal processing architecture

• Channel isolation with crosstalk suppression (~30 dB)

Performance Characteristics

• Input scan time: 0.4 ms maximum

• Output update time: 0.3 ms maximum

• Input filter response: 5 ms

• Resolution: 12-bit (4096 counts)

• Accuracy at 25°C: ±0.3% typical of full scale

• Maximum accuracy: ±0.5% full scale
