Product Overview
When precise temperature monitoring or low-level millivolt signal integration is critical, the GE IC200ALG630 delivers reliable performance. This analog input module from the VersaMax I/O series, formerly manufactured by GE Intelligent Platforms and now under Emerson Automation, provides seven input channels for direct wiring of thermocouple sensors and millivolt sources. Its 16-bit resolution ensures accurate data conversion for demanding industrial applications.
Technical Specifications
The IC200ALG630 offers a digital resolution of 15 bits plus sign, with an update rate of 60 to 70 milliseconds. At 25 degrees C, accuracy reaches +/-0.2% on voltage measurement and +/-0.15% on thermocouple temperature measurement. Temperature sensitivity from 0 to 60 degrees C is +/-0.004% of reading plus +/-1.5 microvolts per degree C referred to input. The module operates at 50/60 Hz frequency, with a channel update rate of approximately 60 ms per channel at 60 Hz and 70 ms per channel at 50 Hz. Backplane current consumption is 125 mA maximum on both 5V and 3.3V outputs.
Industry Applications
In process industries such as chemical plants and refineries, the IC200ALG630 monitors temperature from thermocouple types J, K, T, S, and R. Its millivolt input capability also suits transducer outputs in pressure or flow measurement systems. The module's diagnostic features—open thermocouple detection, over/under range alarms, and thermistor error reporting—help reduce unplanned downtime.
Installation & Setup Guidance
Mount the IC200ALG630 onto a VersaMax backplane and connect using shielded twisted pair cables for signal integrity. Configure cold junction compensation options—no cold junction, remote, fixed, or local—via the programming software. Ensure the operating temperature stays between 0 and 60 degrees C ambient. The OK LED indicates backplane power status: green when active, amber when faulted.
Maintenance & Reliability
Routine inspection of connections and thermocouple wiring helps maintain accuracy. The module's optical isolation and frame-to-ground isolation rating of 250 VAC continuous (1500 VAC for 1 minute) protect against electrical noise and transients. No thermal derating occurs within the specified temperature range, supporting long-term reliability.
Compatibility & Integration
The IC200ALG630 integrates with VersaMax backplanes and controllers. It supports thermocouple sensors J, K, T, S, and R, as well as millivolt signals of +/-19.5mV, +/-39mV, +/-78.125mV, +/-156.25mV, +/-312.5mV, and +/-625mV. The module uses a 16-bit analog-to-digital converter per channel for individual signal conversion.
Selection Guide & Purchasing Advice
Before ordering, verify that your system uses a VersaMax backplane and that the IC200ALG630's 7-channel configuration meets your input count.
