Parameters Parameter Specification Product Range Modicon TM3 Modular I/O System Module Type High-Speed Thermocouple Input Module Commercial Reference TM3TI4G Number of Channels 4 Input Type Thermocouple (TC) Supported Thermocouple Types J, K, T, E, N, R, S, B, C (configurable per channel) Measurement Range Depends on TC type (e.g., Type K: -270°C to +1372°C) Resolution 0.1°C or 0.1°F (1/10th degree) Accuracy Typically ±0.3% of reading ±1°C (for Type K at 23°C ±5°C). Cold Junction Compensation (CJC) Integrated, automatic. Open Wire Detection Yes (detects broken thermocouple). Conversion Time 50 ms per channel (for all channels). Filtering Configurable digital filter (averaging) to stabilize readings. Isolation 500 V AC between field side and bus side. Channels are grouped in pairs with internal common. Connection Removable screw terminal block. Diagnostic LEDs CH1-4 ERR (red): Indicates channel-specific error (e.g., open wire, overrange). Module STATUS LED (Green/Red for power, communication, error). Bus Interface TM3 bus via TM3 base (e.g., TM5SBER2). Power Consumption From 5V bus: 130 mA (typical). Operating Temperature 0°C to +60°C Storage Temperature -25°C to +70°C Relative Humidity 10% to 95% (non-condensing) Certifications CE, UL, cUL, RoHS compliant.
