Parameters Parameter Specification Product Range Modicon TM7 Distributed I/O System Module Type Analog Input Module (for Thermocouple) Commercial Reference TM7BAI4CLA Number of Channels 4 Sensor Type Thermocouple (TC) Supported Thermocouple Types J, K, T, E, N, R, S, B, C (configurable per channel) Measurement Range Dependent on TC type (e.g., Type K: -270°C to +1372°C) Resolution 0.1°C or 0.1°F Accuracy Typically ±0.3% of reading ±1°C (for Type K, within a specified range, e.g., 0°C to 400°C). Cold Junction Compensation (CJC) Integrated, automatic. Open Wire Detection Yes (detects broken thermocouple). Update Time Typically 100 ms per channel (configurable). Filtering Configurable digital filtering for signal stabilization. Isolation Channel-to-channel and channel-to-bus isolation (typically 500 V AC). Connection Removable screw terminal block or pluggable connector. Diagnostic LEDs Green LED per channel (indicates active/valid measurement). Red LED per channel (indicates fault, e.g., open wire, out-of-range). Module STATUS LED (system status). Communication Interface Integrated CANopen or Modbus TCP (via the TM7 communication head). Power Supply 24 V DC (via integrated power connector). Operating Temperature -25°C to +70°C Storage Temperature -40°C to +85°C Relative Humidity 10% to 95% (non-condensing) Protection Class Typically IP67 (when connectors are properly mated). Mounting Direct mounting or on a DIN rail (with adapter). Certifications CE, UL, cUL, RoHS compliant.
