GE Fanuc IC200ALG325 Analog Output Module 8 Channels

IC200ALG325 GE Fanuc 13-Bit Voltage Output

Product Introduction

The GE Fanuc IC200ALG325 is an 8-channel analog voltage output module from the VersaMax I/O family. This module provides eight single-ended output channels, offering both unipolar (0-10 VDC) and dual-polarity (-10 to +10 VDC) ranges with 13-bit resolution. Specifically, it delivers high precision and fast update rates, making it suitable for multi-axis control, process automation, and test equipment. Therefore, the IC200ALG325 excels in applications requiring multiple analog outputs with minimal channel interaction. Additionally, its diagnostic features and configurable output defaults enhance system reliability and safety.

Technical Specifications

This section details the core capabilities of the IC200ALG325. First, it features eight analog voltage outputs, each configurable for either 0-10 VDC or -10 to +10 VDC operation. This flexibility allows the module to accommodate both unipolar and dual-polarity field devices. Furthermore, the 13-bit resolution provides finer voltage steps compared to 12-bit modules, enabling more precise control. The maximum update rate is 10 ms, ensuring timely response in dynamic control loops.

Moreover, the IC200ALG325 achieves high accuracy across its operating range. The module maintains consistent performance without requiring thermal derating, even in elevated temperatures. Specifically, it operates reliably from 0 to 60°C, with accuracy variation limited to ±1% of full scale. Additionally, the channel-to-channel isolation minimizes crosstalk, ensuring each output remains independent and stable.

For power requirements, the module draws a maximum of 50 mA from the 5V backplane supply. However, the output circuits require an external power supply rated for 18 to 30 VDC. This dual-power architecture isolates field wiring from the logic circuits, enhancing safety and noise immunity. Furthermore, the module provides 250 VAC continuous isolation (and 1500 VAC for one minute) between the user input and logic/frame ground, protecting against voltage transients.

Diagnostics and LED Indicators

The GE Fanuc IC200ALG325 includes two LED indicators for status monitoring. The OK LED confirms that backplane power is present and sufficient for operation. The second LED indicates field-side power availability. Furthermore, the module incorporates comprehensive diagnostic tools that detect loss of user-side power. These diagnostics generate reports for the host CPU, enabling rapid fault identification and preventive maintenance. Additionally, the module supports configurable output defaults. For instance, you can set the outputs to hold their last state or revert to a safe value (such as 0 VDC) in case of a CPU stop or module fault. This feature prevents unintended actuator movements during system interruptions.

Mechanical and Environmental Parameters

The GE Fanuc IC200ALG325 operates reliably across a wide temperature range of 0 to 60°C. It withstands humidity levels from 5% to 95% non-condensing. Importantly, the module does not require thermal derating, meaning its accuracy remains stable even at higher temperatures. The compact design fits standard VersaMax racks and terminal bases, saving valuable panel space. Additionally, the robust construction resists vibration and shock, ensuring long-term durability in harsh industrial environments.

Installation Guidelines

Installing the IC200ALG325 is a straightforward procedure. First, power down the backplane and disconnect the external supply. Then, mount the module onto a compatible VersaMax terminal base and secure it with the retaining screws. Next, connect your field wiring to the designated terminals, using shielded twisted-pair cables for optimal noise immunity. Additionally, verify that your external power supply matches the required voltage range (18-30 VDC). After completing all connections, reapply power and observe the LED indicators. The OK LED should light up green, confirming backplane power. Finally, configure the output range and default behavior via the host CPU or network interface unit.

Frequently Asked Questions (FAQ)

Q1: What output ranges does the IC200ALG325 support?
The IC200ALG325 offers eight configurable outputs. You can set each channel for either 0-10 VDC (unipolar) or -10 to +10 VDC (dual-polarity), providing flexibility for different field devices.

Q2: What is the resolution and update rate of this module?
This module features 13-bit resolution, offering finer voltage steps than standard 12-bit modules. The maximum update rate is 10 ms, ensuring timely response in control applications.

Q3: Does the IC200ALG325 require an external power supply?
Yes, the output circuits need an external power supply rated for 18-30 VDC. The module draws backplane power (5V, 50 mA max) for its logic circuits.

Q4: What happens if the CPU stops or the module faults?
You can configure the output default behavior. The IC200ALG325 can either hold its last output state or revert to a safe value (e.g., 0 VDC). This configurable feature ensures safe system operation.

Q5: How do I check the module's operational status?
Two LED indicators provide status information. The OK LED shows backplane power is present, and the field LED indicates external power availability. Diagnostic tools also report any loss of user-side power to the host CPU.
