The Newport 8325D is a dual-channel temperature control module designed for independent thermal management of two heating or cooling elements. Each channel delivers up to 15W of power output with 16-bit precision control and measurement technology. The module integrates into Newport 8000 series mainframe controllers, supporting multiple sensor types including thermocouples (J, K, T, E, R, S, B, C, N, J DIN), Pt RTDs (100, 500, 1000 Ω with 385 or 392 curves), thermistors, AD592, and LM335 series sensors. Analog inputs accept thermocouple, Pt RTD, DC voltage (±0.1, 1.0, 10V), and DC current (0–20, 4–20, 0–24 mA) with scalable engineering unit conversion.
