Description
General Electric IC200ALG620 is a VersaMax RTD analog input module engineered to acquire accurate measurement data from up to four independent 3-wire and/or 4-wire RTD sensors. The module supports platinum, nickel, nickel/iron, and copper RTDs, providing flexible integration into a wide range of industrial temperature monitoring systems. With 16-bit resolution and built-in excitation current generation, IC200ALG620 eliminates the need for an external power supply while maintaining precise signal acquisition.

Each channel on General Electric IC200ALG620 can be individually configured and activated according to application requirements. Users can select measurements in tenths of ohms, tenths of degrees Celsius, or tenths of degrees Fahrenheit. The module also offers selectable resistance ranges of 0–500 ohms and 0–3000 ohms, allowing IC200ALG620 to adapt to various sensor types and process conditions without additional hardware modifications.

To enhance measurement reliability, General Electric IC200ALG620 incorporates strong noise rejection characteristics, including 60 dB normal mode rejection at 50/60 Hz and 120 dB common mode rejection with 100-ohm imbalance. The module supports a maximum common mode voltage of 3 V and a maximum normal mode voltage of 5 V. Digital resolution reaches 15 bits plus sign, enabling IC200ALG620 to provide detailed and stable process data for critical industrial applications.

Diagnostic functionality is an important feature of General Electric IC200ALG620. The module reports overrange, underrange, open wire, input short, high alarm, low alarm, and non-volatile memory storage diagnostics directly to the I/O Fault Table. Automatic A/D calibration is performed during power-up and repeated periodically to compensate for ambient temperature changes, helping IC200ALG620 maintain consistent measurement accuracy throughout operation.

Status monitoring is simplified through integrated LED indicators. The FLD PWR LED confirms the presence of both backplane and field-side power, while the OK LED provides module status information including normal operation, boot mode, update mode, self-diagnostic errors, and loss of backplane power. General Electric IC200ALG620 is compatible with VersaMax PLC CPUs, Genius NIUs, Profibus NIUs, and DeviceNet NIUs meeting the specified firmware requirements, making it a versatile solution for distributed industrial automation systems.
