WAGO 750-469/000-006 | 2-Channel Analog Input Module | Thermocouple J | Diagnostics

2-Channel Analog Input Module Thermocouple J with Diagnostics

The WAGO 750-469/000-006 is a high-precision 2-channel analog input module specifically engineered for direct connection of Thermocouple J temperature sensors in industrial automation and process control applications . This module combines accurate temperature measurement with comprehensive diagnostic capabilities, ensuring reliable operation and rapid fault identification in critical temperature monitoring systems. Part of the versatile WAGO 750 Series I/O system, this module delivers professional-grade performance in an ultra-compact 12 mm wide housing .

Key Features and Product Highlights

• 2-Channel Thermocouple J Input: Provides two dedicated channels for direct connection of Thermocouple J (iron-constantan) temperature sensors, supporting a wide measurement range from -100°C to +1200°C .

• Integrated Per-Channel Diagnostics: Features comprehensive diagnostic capabilities with dual LED indicators per module. A green LED indicates operational readiness and error-free communication with the bus coupler, while a red LED provides immediate visual notification of wire break conditions .

• Internal Galvanic Isolation: Includes 500 V system/field isolation that enables operation of grounded sensors without measurement errors or ground loop issues .

• Automatic Cold Junction Compensation: Built-in cold junction compensation at each pair of terminal blocks mitigates clamping unit offset voltage across the entire 0–55°C operating range, ensuring accurate temperature measurements regardless of ambient conditions .

• High-Resolution Measurement: Delivers 0.1°C resolution across the full temperature range with automatic linearization of the entire thermocouple curve, eliminating the need for external signal conditioning .

• CAGE CLAMP® Connection Technology: Utilizes 8 x WAGO's proven CAGE CLAMP® spring-pressure connection technology for tool-free, vibration-proof, and maintenance-free wiring of solid, stranded, and fine-stranded conductors .

• Ultra-Compact Design: Occupies only 12 mm (0.472 inches) on the DIN rail, enabling high-density I/O configurations in space-constrained control cabinets .

• Direct Shield Connection: Features integrated shield connection that routes directly to the DIN rail, simplifying EMC-compliant installation and improving noise immunity .
