Description

TC-304-01: Product Overview
The ICS Triplex TC-304-01 is a versatile and robust Temperature Transmitter Module designed for high-precision measurement and monitoring in industrial process control applications. As part of the ICS Triplex Trusted family—known for its safety-critical and fault-tolerant capabilities—the TC-304-01 is engineered to interface with a wide range of temperature sensors, providing highly reliable temperature data to ICS Triplex control systems. This ensures accurate temperature measurements for control, monitoring, and safety applications in industries where uptime, precision, and safety are paramount.
The module’s core function is to convert raw temperature sensor signals (e.g., thermocouple, RTD, thermistor) into standardized digital outputs for integration with ICS Triplex controllers. It supports multiple sensor types, including J, K, T, E, R, S, B thermocouples (range: -200°C to +1372°C), PT100/PT1000 RTDs (-200°C to +850°C), and thermistors (-40°C to +150°C). Built-in signal conditioning—including filtering, linearization, and amplification—optimizes sensor inputs for accuracy, while dual redundant 24V DC power inputs ensure high availability and continuous operation.
Designed for harsh industrial environments, the TC-304-01 features a compact DIN rail-mountable form factor (100mm W x 120mm H x 70mm D) and IP20 protection class. It includes real-time module status monitoring, self-diagnostics for connected sensors, and fault detection (e.g., thermocouple burnout). The TC-304-01 is ideal for industries such as oil and gas, chemical processing, power generation, and manufacturing, where precise temperature control and safety are critical.

Core Features & Customer Value​
Multi-Sensor Compatibility: The TC-304-01 supports a wide range of temperature sensors (thermocouples, RTDs, thermistors), eliminating the need for multiple specialized modules. This simplifies system design, reduces inventory costs, and provides flexibility for diverse industrial applications—from chemical reactors to power plant boilers. For example, a chemical plant can use the same module to monitor both thermocouple-based reactor temperatures and RTD-based pipeline temperatures, streamlining maintenance and calibration.
High Precision and Accuracy: With ±0.1°C accuracy for common sensors, the TC-304-01 delivers reliable temperature data critical for process optimization and safety. In power generation, precise temperature monitoring of turbine components prevents overheating and ensures efficient operation. The module’s built-in linearization and cold-junction compensation further enhance accuracy, reducing errors from sensor drift or environmental factors.
Fault Tolerance and High Availability: Dual redundant 24V DC power inputs and real-time diagnostics ensure the module operates continuously even if one power source fails. The TC-304-01 also includes self-diagnostics for connected sensors, alerting operators to issues like thermocouple burnout or wiring faults before they impact the process. This fault tolerance is essential for industries like oil and gas, where unplanned downtime can result in significant financial losses or safety risks.
SIL 3 Certification for Safety: The TC-304-01 meets SIL 3 requirements, making it suitable for safety-critical applications such as emergency shutdown (ESD) systems or fire and gas (F&G) protection. In a refinery, for instance, the module can monitor critical reactor temperatures and trigger a safe shutdown if thresholds are exceeded, preventing catastrophic failures.
Easy Integration and Installation: Compatible with ICS Triplex communication buses and DIN rail mounting, the TC-304-01 integrates seamlessly into existing control systems. Its compact size and IP20 rating make it ideal for panel-mounted or rack-mounted installations in industrial facilities. The module also supports remote terminations (up to 50 feet from the chassis), reducing wiring complexity in large plants.
