Key Features

1. Multi-Channel Precision Temperature Measurement
   • Accepts 7 thermocouple inputs (J, K, T, S, R) or linear mV signals for versatile data acquisition.
   • Delivers 16-bit resolution and high accuracy for critical process temperature monitoring.
2. Integrated Cold Junction Compensation (CJC)
   • Automatically compensates for ambient temperature changes at the module terminals, ensuring stable and precise temperature readings without external circuitry.
3. Backplane-Powered, No External PSU Needed
   • Draws all operating power from the VersaMax PLC backplane, reducing wiring complexity and eliminating external power supply requirements.
4. Per-Channel Configuration & Diagnostics
   • Each channel can be independently set to thermocouple or mV mode.
   • Detects open/short circuits, sensor faults, and out-of-range conditions, reporting alarms to the PLC for proactive maintenance.
5. Rugged & Compact Industrial Design
   • Built for 0°C to +60°C operation, with resistance to vibration and electrical noise.
   • Compact form factor saves rack space in VersaMax PLC systems.
