Key Features

• 7‑Channel High‑Density Input: Accepts up to 7 independent thermocouple or mV sensor inputs, reducing rack space and wiring complexity for multi‑point monitoring.
• Multi‑Sensor Compatibility: Supports J/K/T/S/R thermocouples and six standard mV ranges, covering diverse industrial temperature and low‑level voltage measurement needs.
• 16‑Bit High Resolution: Delivers 15 bits plus sign resolution for precise detection of small temperature or voltage changes, ensuring reliable process control.
• Exceptional Accuracy: Provides ±0.15% temperature accuracy and ±0.2% voltage accuracy at 25°C, maintaining stability across operating conditions.
• On‑Board Automatic CJC: Integrates automatic cold‑junction compensation with four configurable modes, eliminating errors from ambient temperature fluctuations at terminals.
• Automatic A/D Calibration: Performs self‑calibration at power‑up and periodically during operation to offset thermal drift, ensuring long‑term measurement stability.
• Strong Noise Rejection: Uses differential input design and high common‑mode rejection to suppress electrical interference from motors, VFDs, and industrial machinery.
• Channel‑to‑System Isolation: Offers 1500 VAC isolation between field inputs and PLC logic, protecting the system from voltage spikes and ground loops.
• Software‑Configurable Parameters: Allows selection of sensor type, temperature unit (°C/°F), and scaling via VersaMax programming software, no hardware jumpers needed.
• Compact Rack‑Mount Design: Fits standard VersaMax racks with a lightweight, space‑saving form factor, minimizing cabinet space and installation time.
• Diagnostic Capabilities: Detects open circuits, sensor faults, and over‑range conditions, reporting errors to the PLC fault table for proactive maintenance.
