Repair GE-Emerson IC695ALG312 PACSystems RX3i Isolated Thermocouple Input Module

The GE-Emerson IC695ALG312 PACSystems RX3i Isolated Thermocouple Input Module is ideal for temperature-related tasks and the integration of field transducers. It facilitates direct wiring compatibility with a range of sensors, including Thermocouple Types J, K, T, E, R, S, B, N, or C, as well as voltage signals such as +/-150mV or +/-50mV.

The IC695ALG312 features a total of twelve (12) input channels, each equipped with an integrated Analog to Digital Converter (ADC) offering varying resolutions between 1.5 and 16 bits, contingent upon the configured input filters. The data converted through the built-in ADC circuit can be set to either a 16-bit integer stored within a 32-bit register or a 32-bit real number. Every channel possesses an integration time that spans from 15 ms to 120 ms, accompanied by a Voltage accuracy rating of approximately +/- 0.1% of the voltage span at 25 degrees Celsius and an accuracy of about +/- 0.25% of the span across the entire temperature range. Additionally, this module exhibits a repeatability metric, achieving 0.05% of the voltage span under consistent temperature conditions over a 30-second timeframe.
