The IC200ALG261 is a high-performance analog input module from the VersaMax family, manufactured by GE Fanuc. It provides eight differential input channels, making it ideal for applications requiring noise-immune signal measurement. This module interfaces with up to eight differential voltage sources. It draws its operating power directly from the VersaMax backplane, eliminating the need for an external supply. With intelligent processing support and built-in diagnostics, the IC200ALG261 delivers reliable performance in demanding industrial environments.
The IC200ALG261 features eight differential analog inputs. Differential inputs offer superior noise rejection compared to single-ended configurations. Each channel measures the voltage difference between its positive and negative terminals, effectively canceling common-mode noise. This design makes the module particularly suitable for applications with long cable runs or electrically noisy environments. The module accepts voltage signals and converts them to digital data for the PLC's CPU.
This module draws its operating power from the VersaMax backplane. The IC200ALG261 consumes 200 mA at 5 VDC. This moderate current draw fits well within the power budget of most VersaMax systems. For normal operation, no external power supply is required. However, if you connect transceiver devices to the module, you must install a separate external power source for those transceivers. The module itself remains powered solely by the backplane.
The IC200ALG261 supports intelligent processing from the PLC's CPU or NIU (Network Interface Unit). This capability allows the module to offload some processing tasks from the main processor. For example, it can perform scaling, filtering, or diagnostic functions locally. This reduces the CPU's workload and improves overall system responsiveness. The intelligent processing feature makes this module a valuable component for complex automation systems.
A single green OK LED is located on the front panel of the IC200ALG261. This LED illuminates under three conditions: backplane power is present, internally generated field power is functioning correctly, and the module has been properly configured and recognized by the backplane. If the LED is off, it indicates a problem with power or configuration. Additionally, the module includes a diagnostic feature that reports loss of internal power for its field-side circuits. This diagnostic data is accessible through the programming software.
The IC200ALG261 provides isolation between the user inputs and the logic circuits. It also offers isolation between the inputs and frame ground. The isolation rating is 1500 VAC for one minute and 250 VAC continuous. This protection safeguards the PLC backplane from voltage spikes and ground loops. However, note that this module does not provide group-to-group or channel-to-channel isolation. All eight inputs share a common reference within the module.
The IC200ALG261 requires a termination carrier for field wiring connections. Compatible carriers include terminal-style units such as IC200TBM001, IC200TBM002, and IC200TBM005. Connector-style carriers like IC200CHS003 are also available. Additionally, compact terminal-style carriers IC200CHS022 and IC200CHS025 work with this module. For differential connections, each input requires two wires: positive and negative. Use shielded twisted-pair cables to preserve signal integrity. Ground the cable shield at the source device whenever possible.
The IC200ALG261 integrates seamlessly into any VersaMax PLC or distributed I/O system. It works with GE Fanuc controllers that support the VersaMax backplane. You can install this module in any slot within a VersaMax rack. No special addressing is required beyond standard I/O mapping. The module's intelligent processing capability allows it to function efficiently even in large systems with many I/O points. Its differential inputs make it an excellent choice for applications requiring high noise immunity.
The IC200ALG261 is ideal for applications with long cable runs or electrically noisy environments. In factory automation, it monitors signals from sensors located far from the control cabinet. In process industries, it reads differential outputs from pressure transmitters, load cells, and thermocouple amplifiers. Its differential inputs effectively reject common-mode noise, ensuring accurate measurements. For system upgrades, this module offers a direct replacement for older analog modules with enhanced noise rejection.
