The IC200ALG266 delivers high-performance analog voltage input for the Versamax I/O system. GE Intelligent Platforms originally designed this module, and Emerson Automation now continues its production. This module acts as a critical interface between voltage-based field sensors and the main PLC processor. Its design prioritizes channel density, measurement accuracy, and robust diagnostics. Consequently, the IC200ALG266 suits a wide variety of industrial automation applications.
This voltage input module offers 15 single-ended input channels within a single group. The IC200ALG266 accepts a nominal input signal range of -10 VDC to +10 VDC. This wide range accommodates many standard industrial voltage sensors and transducers. The module provides a 15-bit analog-to-digital conversion resolution. This translates to an actual resolution of 0.3125 mV per count. Therefore, the module can detect extremely fine changes in the input voltage signal.
The IC200ALG266 achieves a typical accuracy of ±0.3% of full scale at 25°C. Its maximum accuracy is ±1% of full scale at 60°C. Each input channel includes a filter response of 32 Hz ±20%. The module updates all 15 channels at a rapid maximum rate of 7.5 milliseconds. This speed ensures your control system receives timely data for effective real-time monitoring. The module draws its operating power exclusively from the PLC backplane, with a maximum current consumption of 150 mA at 5 VDC. Thus, you do not need an additional external power supply.
Diagnostic capabilities significantly enhance the reliability of this input module. The IC200ALG266 can detect a loss of internal power, quickly alerting you to potential issues. It also monitors for analog-to-digital conversion errors. Specifically, the module identifies a conversion failure when the AD converter delivers an output greater than 6% of the full-scale value. The module reports all diagnostic statuses directly to the CPU. From there, the information can appear on HMIs or SCADA systems as a fault or bad signal quality, greatly simplifying troubleshooting.
The IC200ALG266 features software-configurable input states in response to a CPU stop or module error. You can configure each channel for a default state or to hold its last state. This functionality proves especially valuable for implementing safe start-ups, particularly during power interruptions. It helps prevent unexpected equipment behavior during system recovery.
This module includes protective features that ensure safe operations and extend the lifespan of both the module and its inputs. The IC200ALG266 protects itself against overvoltage levels higher than 30 Volts DC. This protection prevents damage from voltage spikes and surges. Notably, the operations of each input are independent. If one channel enters a fault state, it will not affect the functioning of the rest of the inputs. This individual channel operation enhances overall system reliability.
An "OK" LED status indicator resides on the module's faceplate. This LED confirms successful power-up and the download of a valid configuration. It also signals that the backplane has recognized the IC200ALG266. This simple visual indicator provides a quick and effective first check of module health. However, be aware that radiofrequency interference can affect accuracy. In such environments, the module's accuracy may derate by up to ±2%. Therefore, proper installation and shielding remain important considerations.
The IC200ALG266 offers robust electrical isolation to ensure safety and minimize noise interference. It provides 250 Volts AC of continuous user input to logic isolation. Moreover, it delivers 1500 Volts AC of user input to frame ground isolation for one minute. However, you should note that there is no isolation between individual channels, as all 15 channels share a single group.
Proper installation optimizes module performance. You can mount the IC200ALG266 on terminal-style, compact terminal-style, or connector-style I/O carriers. It occupies a single slot within the Versamax system. For channel wiring, always employ shielded twisted pair cables. This practice effectively reduces electrical noise and preserves signal integrity. The module supports sink wiring configuration for all 15 channels.
The IC200ALG266 communicates its data to the host controller using 15 words of analog input data. Its single-group configuration means all inputs share a common reference point. This design simplifies wiring, especially when multiple sensors share a common return. The module provides a cost-effective and dense solution for adding 15 voltage inputs to your Versamax distributed I/O system. Its software-configurable fault response and independent channel operation provide additional flexibility for various applications.
