IC200ALG328 | GE VersaMax | Output Module, 12 single-ended

GE Fanuc IC200ALG328 VersaMax Analog Output Module — 12-Channel, 13-Bit Current Output

The IC200ALG328 is a 12-channel, 13-bit current analog output module from the GE Fanuc VersaMax series. It provides twelve 4–20 mA current-sourcing outputs (default), with an optional 0–20 mA range configurable via a carrier jumper. Each channel can deliver approximately 20.38 mA to drive output loads, making it ideal for precise process control, valve positioning, and actuator signaling in industrial automation environments.

Scaling & Output Behavior

In 0–20 mA range mode, 0 mA corresponds to 0 %AQ counts, and 20 mA corresponds to +32,000 %AQ counts. In 4–20 mA range mode, 0 %AQ counts corresponds to 4 mA, and +32,000 %AQ counts corresponds to 20 mA. When installed in a PLC rack, negative command values are converted to 0 mA regardless of range selected.

Configuration & Diagnostics

• Range Jumper (JMP1): No jumper = 4–20 mA (default); Jumper installed = 0–20 mA
• Hold Jumper (JMP2): No jumper = outputs hold last state on power/communication loss; Jumper installed = outputs default to 0 mA (0–20 mA range) or 4 mA (4–20 mA range)
• Diagnostics: Loss of User Side Power fault reporting
• Thermal Derating: Applicable to IC200ALG328 only; dependent on ambient temperature, external voltage, and module/DIN rail orientation

Compatibility

• PLC CPU firmware version 2.1 or later
• VersaPro software version 2.0 or later
• Ethernet NIU EBI001 firmware 1.10 or later
• Genius NIU GBI001 firmware 2.20 or later
• Profibus NIU PBI001 firmware 2.20 or later
• DeviceNet NIU DBI001: Not supported

Installation Guide

1. Pre-Installation Check: Inspect shipping containers for damage. Record all serial numbers. Save packing materials for potential return.
2. Carrier Selection: Mount the module on a compatible VersaMax I/O carrier (IC200CHSxxx series). Ensure the carrier supports three rows of terminals for proper wiring.
3. Jumper Configuration: Set the Range Jumper (JMP1) and Hold Jumper (JMP2) on the carrier BEFORE applying field or backplane power. Changes with power applied may damage the module.
4. External Power Connection: Connect a regulated +18 to +30 VDC external power supply to the field-side terminals. This supply is mandatory for output operation.
5. Backplane Power: Ensure the +5V backplane bus can supply up to 50 mA for this module.
6. Wiring: Use shielded twisted-pair cables for analog output signals to minimize noise. Connect shield at one end only (typically at the panel ground).
7. Grounding: Maintain proper frame ground connection. The module provides optical isolation between user-side circuits and logic/frame ground.
8. LED Verification: After power-up, verify the OK LED (backplane power) and FLD PWR LED (field power) are both illuminated.
9. Thermal Consideration: If operating at 30 VDC with high ambient temperatures, consult the thermal derating chart in the official manual (GFK-2526) to determine maximum active channels.

FAQ — Frequently Asked Questions

Q: Does the IC200ALG328 require an external power supply?
A: Yes. The module requires an external +18 to +30 VDC power supply for the analog output circuits. Backplane power alone is insufficient for field-side operation.

Q: Can I change the output range from 4–20 mA to 0–20 mA?
A: Yes. Install a jumper on the carrier's JMP1 pins to switch to 0–20 mA mode. Remember to update the corresponding configuration parameter in your PLC programming software.

Q: What happens to outputs if the PLC stops or communication is lost?
A: By default (no Hold Jumper), outputs hold their last commanded state. With the Hold Jumper (JMP2) installed, outputs default to the low end of range (0 mA or 4 mA depending on range setting).

Q: Is the IC200ALG328 compatible with DeviceNet?
A: No. The IC200ALG328 is not supported by the DeviceNet NIU (DBI001). It is compatible with Ethernet, Genius, and Profibus NIUs, as well as direct PLC CPU racks.

Q: What is the maximum load resistance per channel?
A: The maximum resistive load is 800 Ω per channel. Exceeding this may degrade output accuracy or cause the module to fail to reach full-scale current.

Q: Does this module support hot-swapping?
A: VersaMax modules generally support hot insertion/removal when properly configured, but always follow your system’s safety procedures and ensure field power is disconnected before removing the module to prevent damage.

Selection Tips — How to Choose the Right VersaMax Analog Output Module

• Need 12 current outputs? The IC200ALG328 is your best choice. For 8 current outputs, consider the IC200ALG326.
• Need voltage outputs? Choose IC200ALG325 (8-channel voltage) or IC200ALG327 (12-channel voltage) instead.
• Need higher resolution (16-bit)? Upgrade to the IC200ALG331 (4-channel, 16-bit isolated voltage/current output).
• Need mixed input/output? Consider IC200ALG430/431/432 analog mixed modules.
• Verify external power availability: All VersaMax analog output modules require external DC power. Ensure your panel has adequate capacity.
• Check NIU compatibility: If using a Network Interface Unit, confirm firmware version compatibility before ordering.
