Description

The 3500/61 136711-02 RTD/TC I/O Module provides six channels of automated temperature monitoring using RTD or Thermocouple inputs. The 3500/61 136711-02 conditions signals from 1 to 6 transducers, with input impedance greater than 10 MΩ per lead, and compares them to user-programmed alarm setpoints. Each channel delivers 4–20 mA recorder output proportional to full-scale temperature, with 0.3662 µA per bit resolution and ±0.4% error across the temperature range. The 3500/61 136711-02 supports RTD current sources at 925 ±15 µA and can be configured via 3500 Rack Configuration Software for RTD, TC, or mixed inputs. Isolated TC modules provide 250 Vdc channel-to-channel separation to reduce interference. Operating temperature ranges from -30°C to +65°C, and multiple 3500/61 136711-02 modules can be installed in Triple Modular Redundant (TMR) arrangements for automated voting logic, enabling precise alarm activation and continuous temperature data monitoring in industrial systems.

Applications

Monitor Industrial Equipment Temperature
The 3500/61 136711-02 accepts 1 to 6 RTD or Thermocouple signals, conditioning each channel and comparing it to programmed alarm setpoints. With 4–20 mA recorder output and 0.3662 µA per bit resolution, the 3500/61 136711-02 enables automated detection of high temperatures in turbines, pumps, and compressors.

Integrate Temperature Data into Control Systems
Each channel of the 3500/61 136711-02 outputs proportional current signals for SCADA or DCS systems, allowing automated cooling, shutdown, or alarm routines based on real-time temperature readings.

Configure Mixed RTD and TC Inputs
Using 3500 Rack Configuration Software, the 3500/61 136711-02 can measure RTD, TC, or mixed input types. Isolated TC modules provide 250 Vdc channel-to-channel separation, ensuring accurate readings in electrically noisy industrial environments.

Implement Triple Modular Redundant Voting
Three 3500/61 136711-02 modules installed adjacently in TMR arrangements allow automated voting logic for temperature alarms, preventing single-point failures in high-risk automated processes.

Competitive Advantage

Fast Alarm Activation with Quantified Accuracy
The 3500/61 136711-02 triggers automated alarms immediately when temperature thresholds are exceeded. Each channel supports ±0.4% error across its measurement range, enabling precise automated shutdown or alert actions.

High-Resolution Recorder Output
Each of the six channels on the 3500/61 136711-02 provides 4–20 mA output, with 0.3662 µA per bit resolution. This high-resolution output allows automated control systems to detect even minor temperature changes and execute corrective actions.

Supports Mixed RTD and TC Inputs with Electrical Isolation
The 3500/61 136711-02 accepts RTD, TC, or mixed signals. Isolated TC modules provide 250 Vdc channel-to-channel separation, reducing interference and ensuring reliable automated data collection in electrically noisy industrial environments.

Automated Triple Modular Redundant Voting
Three 3500/61 136711-02 modules installed in TMR configuration allow automated voting logic. This ensures that alarm decisions are based on consistent data from multiple channels, preventing false alarms and minimizing single-point failures.
