LETC72M2

Designed for modern control desks, industrial ovens, and batch processing systems, the Lubi LETC72M2 bridges the gap between local operator control and remote SCADA supervision. Operators benefit from distinct two-color dual displays (White for PV and Green for SV), while automation engineers can read process values, modify setpoints, and poll alarm registers via the 2-wire RS-485 Modbus RTU port.

The LETC72M2 handles both heating and cooling processes, featuring a responsive auto-tuning PID controller that suppresses temperature cycling during load fluctuations. It includes programmable sensor offsets, soft alarm delays, and password-locked access levels to prevent accidental parameter tampering.

Key Features:

• Dual 4-digit display: 0.56" White LED (PV) and 0.4" Green LED (SV).
• Built-in RS-485 serial communication using standard Modbus RTU protocol.
• Full communications configurability: Baud rates (2400 to 38400 bps), Node Address (1–247), Parity (None/Even/Odd), Data types (Integer/Float).
• Extended measurement ranges: K-Type up to 1200°C; Pt.1 decimal range (-99.9°C to 400.0°C).
• Robust output options: 1 C/O 10A relay and 12V DC SSR drive.
• 6 programmable alarm modes with independent hysteresis and delay timers.
• Front panel TUNE, SSR, RLY, and serial communication indicators.
