IC200ALG328 GE Versamax Analog Output 13-bit

IC200ALG328 GE Versamax Analog Output 13-bit

Product Introduction

The IC200ALG328 from GE Fanuc is a high-channel-count analog output module designed for the Versamax I/O system. This module provides twelve single-ended, current-sourcing outputs, each configurable within the standard 4 to 20mA range. It delivers exceptional signal precision thanks to its 13-bit resolution, ensuring accurate control over field devices like valves and actuators. Moreover, its maximum update rate of 15 milliseconds enables rapid response in time-critical control loops.

Built for flexibility, the IC200ALG328 integrates seamlessly into various network architectures. It works with Ethernet, Genius, Profibus, and DeviceNet firmware. Additionally, it pairs effectively with the IC200ALG326 module for channel scaling, as their characteristics are closely matched. This compatibility makes it an excellent choice for expanding or upgrading existing Versamax installations without major redesign efforts.

Technical Specifications

The IC200ALG328 operates on a 5V backplane current of 550mA maximum, which is essential for system power budgeting. Its field-side power input ranges from 18 to 30 Volts DC. Notably, the module draws approximately 100mA with no load and up to 270mA when all 12 outputs drive full-scale current. The inrush current can reach 2 Amps, so proper power supply sizing is important.

Each channel sources up to 20.38 milliamps to drive output loads. The module’s overall accuracy is rated at 1%, ensuring reliable signal reproduction. Furthermore, two LED indicators clearly show backplane power status and communication health. The built-in diagnostics provide fault reporting, which simplifies maintenance and reduces system downtime.

Thermal Derating and Environmental Considerations

A critical operational factor for the IC200ALG328 is thermal derating. This derating applies specifically when the module operates at 30 Volts DC and is mounted in certain DIN rail positions. The derating level also depends directly on the ambient air temperature surrounding the module. Therefore, system designers must consider these conditions to maintain full output capability and prevent overheating.

For optimal performance, maintain adequate clearance around the module for air circulation. Avoid placing it directly next to high-heat-generating components. If the ambient temperature exceeds specified limits, reduce the output load or improve cabinet cooling accordingly. Following these guidelines will extend the module’s lifespan and preserve its accuracy.

Installation and Wiring Guidelines

Installing the IC200ALG328 correctly ensures reliable operation. Begin by securing the module onto a standard DIN rail within a Versamax station. Although the module supports hot insertion, perform this procedure carefully to avoid electrical transients that could affect other modules or the CPU. Always disconnect field power before wiring to protect both personnel and equipment.

Use shielded twisted-pair cables for all analog output connections to minimize electromagnetic interference. Proper grounding is equally important; connect the cable shield at one end only to prevent ground loops. Additionally, verify that the external power supply provides stable 18-30 VDC with adequate current capacity for all channels simultaneously. These wiring practices are essential for achieving the specified 1% accuracy.
