Description

General Overview

The IC200ALG328 is a high-density analog current output module within the GE VersaMax I/O family, designed to deliver precise signal control for industrial process systems. It converts digital control signals from the PLC backplane into stable analog current outputs for field devices requiring proportional control.

This module is commonly deployed in control loops where accurate current regulation is required for actuators, valves, and process instrumentation.

Output Architecture & Channel Configuration

The module provides:

• 12 × single-ended current output channels

• One shared output group architecture

Each channel supports configurable output ranges:

• 4–20 mA (default configuration)

• 0–20 mA (jumper selectable)

Performance characteristics:

• 13-bit digital-to-analog conversion resolution

• Fine output granularity for precise process modulation

• Channel update cycle optimized for real-time control response

Electrical Performance & Load Capability

Output capability per channel:

• Maximum output current: approximately 20.38 mA (including overrange capability)

• Load resistance range: up to 800 Ω

• Capacitive load tolerance: up to 0.1 µF

• Inductive load tolerance: up to 0.5 H

System timing:

• Module update rate: ≤15 ms

Signal integrity:

• Channel-to-channel isolation performance: ≥70 dB crosstalk rejection

Power Supply & Consumption

Field-side power requirements:

• External supply voltage: 18–30 VDC

• Inrush current: up to 2 A (short duration)

• Full-load current consumption: approximately 270 mA (all channels active)

Backplane power:

• +5 V DC, typical consumption ~50 mA

The separation between logic and field power improves electrical stability and protects control electronics from load-side disturbances.

Isolation & System Protection

• Logic-to-field isolation: 250 VAC continuous

• Dielectric strength: 1500 VAC for 1 minute

Diagnostic functions:

• Field power loss detection

• Module status monitoring via backplane communication

• LED-based operational status indication

Indicators & Diagnostics

• FLD PWR LED: indicates external field power presence

• OK LED: confirms backplane communication and module readiness

These indicators support fast commissioning and fault isolation during maintenance.

Mechanical Design & Installation
