GE IC200ALG620-AA Analog Input RTD Module

Precision Temperature Sensing for VersaMax PLCs

The GE IC200ALG620-AA interfaces directly with three-wire RTD sensors. This module converts resistance changes into accurate temperature readings. It supports platinum (385) and nickel (672) RTD types. Therefore, you can monitor motors, bearings, or process tanks effectively.

Core Technical Specifications

This module weighs only 0.23 kg and measures 112 mm x 65 mm x 56 mm. Consequently, it fits neatly within a standard VersaMax I/O rack. The GE IC200ALG620-AA provides four differential analog input channels. Each channel includes a dedicated spring-clamp terminal block. This design simplifies field wiring and reduces installation time.

Additionally, the unit stores no energy internally for signal processing. It draws all operating power directly from the backplane. The module’s resolution reaches 16 bits across a -200°C to +850°C range. Users also get automatic lead resistance compensation for each channel. This feature eliminates measurement errors from long cable runs.

Installation and Operational Benefits

Furthermore, the GE IC200ALG620-AA includes LED indicators for each channel. These lights show active conversion status at a glance. The module rejects common-mode noise up to 60 dB at 50/60 Hz. As a result, you can deploy it near variable frequency drives safely. The unit also self-calibrates on every power cycle. This process maintains long-term accuracy without user intervention.

Durability and Compliance

This RTD module operates from -20°C to +60°C ambient temperature. It also withstands 5% to 95% non-condensing humidity. The GE IC200ALG620-AA meets UL 508 and CE marking requirements. Consequently, it suits food processing or HVAC monitoring applications.
