The IC200ALG230 is a versatile analog input module originally designed by GE Fanuc and now supported by Emerson Automation. It belongs to the widely adopted VersaMax I/O platform. This module provides four single-ended input channels that you can configure individually. Each channel accepts either voltage or current signals. Specifically, it handles 4-20 mA current loops and ±10 VDC or 0-10 VDC voltage ranges. Therefore, this module fits many analog sensing applications, from pressure transmitters to temperature sensors.
With a 12-bit analog-to-digital converter, the IC200ALG230 delivers solid resolution for industrial signals. For current mode, each count represents approximately 4 µA. For voltage mode, each step equals about 2.5 mV. This level of precision meets the needs of most process control tasks. Moreover, the module’s update rate is 0.4 ms, ensuring timely data delivery to the controller. Additionally, the filter response time is 5.0 ms, which smooths out noise and momentary fluctuations. You can choose between positive-negative voltage ranges (like ±10 V) or unipolar ranges (like 0–10 V) using the onboard jumpers.
Two physical jumpers on the carrier terminal configure the IC200ALG230. The first jumper selects between voltage and current modes. If you choose voltage mode, the second jumper sets either unipolar (0–10 V) or bi-polar (±10 V) operation. These jumpers are easy to access and change during installation. Once configured, the module automatically scales the input data to the appropriate range. This straightforward design simplifies setup without requiring software changes for basic configuration.
Operating power comes directly from the VersaMax backplane, drawing 125 mA at 5 VDC. No external power supply is needed for the module itself. For protection, the IC200ALG230 provides 250 VAC continuous optical isolation between field wiring and the backplane. Furthermore, it withstands 1500 VAC for one minute during hi-pot testing. This robust isolation safeguards the controller from voltage spikes and ground loops.
Two LED indicators are clearly visible on the front face. The INT PWR LED lights up when internal field power is present. Meanwhile, the OK LED confirms that backplane power is active and the module is communicating properly. When a module error occurs, you can configure the response. The IC200ALG230 can either hold the last valid input value or revert to a predefined safe value. Consequently, this feature prevents unexpected process behavior during fault conditions. It also supports loss of internal power diagnostics.
This module integrates seamlessly into any VersaMax PLC or distributed I/O system. It works with both GE Fanuc and Emerson controllers that support the VersaMax backplane. You can place the IC200ALG230 in any slot within a VersaMax rack. No additional addressing steps are required beyond standard I/O mapping. Up to many modules can be installed, limited only by the backplane power budget. Its compact size saves valuable space in control cabinets.
Process industries commonly use the IC200ALG230 for a variety of measurements. It reads signals from pressure transducers, level sensors, and temperature transmitters. It also monitors flow meters and pH sensors in water treatment plants. In manufacturing, this module captures analog data from machine torque or position sensors. Because it supports both current and voltage, it interfaces with a broad range of field devices. For retrofit projects, this module offers a reliable upgrade path while maintaining compatibility with existing wiring.

1. What input types does the IC200ALG230 support?
The IC200ALG230 accepts 4-20 mA current signals and voltage signals of ±10 VDC or 0-10 VDC. You select the mode using onboard jumpers.
2. How do I configure the input range for voltage mode?
Use the second jumper to choose between unipolar (0–10 V) and bi-polar (±10 V). This jumper only applies when the first jumper is set to voltage mode.
3. What is the resolution of the IC200ALG230?
This module has 12-bit resolution. For current, this is about 4 µA per count. For voltage, it is about 2.5 mV per count.
4. Does the module require external 24 VDC power?
No. The IC200ALG230 draws 125 mA at 5 VDC from the backplane. No separate field power supply is needed for the module itself.
5. What happens if the module detects an error?
You can configure the response. The IC200ALG230 can either hold the last value or go to a predefined safe value for each channel. This helps maintain safe process operation.
