Product Overview

The GE H201TI​ is a high-density, 16-channel isolated universal analog input module designed for the PACSystems RX3i​ programmable automation controller platform. It serves as a critical interface for acquiring precise temperature and low-voltage DC signals from a wide array of industrial sensors, converting these analog physical measurements into high-resolution digital values for the controller. The primary function of the GE H201TI​ is to provide a versatile, accurate, and reliable means of monitoring process variables, with a particular strength in handling various thermocouple types alongside millivolt-level DC voltage signals. This makes it an indispensable component in applications requiring extensive temperature monitoring, such as in ovens, environmental chambers, and process heating/cooling systems.

As a member of the versatile RX3i I/O family, the H201TI​ module is engineered for high performance and easy integration. It provides individual channel-to-channel and channel-to-bus isolation, which is crucial for eliminating ground loops and rejecting electrical noise that can severely compromise measurement accuracy in harsh industrial environments. Each of its 16 channels can be independently configured via software for a specific thermocouple type (J, K, T, E, R, S, B, N, C) or DC voltage range (±50mV, ±100mV), offering tremendous flexibility from a single module. The GE H201TI​ delivers this high channel count in a single-slot form factor, optimizing control cabinet space and reducing system cost per point. Its design emphasizes accuracy, stability, and advanced diagnostics, including open wire detection for thermocouples, ensuring reliable data acquisition for critical control and monitoring loops within the RX3i ecosystem.

Main Features and Advantages

The GE H201TI​ module delivers a powerful combination of high channel density, superior signal integrity, and configuration flexibility, making it a standout choice for complex temperature monitoring applications.

High-Density, Configurable Inputs: The most prominent feature of the H201TI​ is its 16 independently configurable input channels in a single module slot. This high density dramatically reduces the hardware footprint and cost associated with monitoring a large number of temperature points. Engineers can mix and match thermocouple types and voltage ranges on a single module, allowing one GE H201TI​ to serve multiple processes or zones with different sensor requirements, simplifying spare parts inventory and system design.

Excellent Isolation and Noise Immunity: The module provides 250V AC of isolation on every channel, both from each other and from the controller’s backplane. This high level of isolation is critical for preventing ground loops—a common source of measurement error and instability—and for protecting the sensitive controller electronics from transient voltages present on sensor wiring. This ensures accurate, reliable readings even in electrically noisy environments like those found near motor drives or welding equipment.

Advanced Diagnostics and Easy Integration: The GE H201TI​ enhances system maintainability with robust diagnostic
