LETC96B2

Lubi LETC96B2 addresses the needs of large-format control panels, furnaces, and extrusion lines requiring physical separation of control and alarm circuits. Unlike smaller controllers that share a single relay, the LETC96B2 incorporates two independent 10A SPDT relays (Terminals 3-4-5 for Relay 1, Terminals 6-7-8 for Relay 2 / Alarm) plus a dedicated 12V DC SSR drive.

Its auto-tuning PID control logic maintains process stability, while the secondary output can be configured for any of the 6 built-in alarm modes (High, Low, In-Band, Out-Band, Absolute Out-Band, Absolute Low). Operating on a wide 100–250V AC supply with built-in noise suppression, the LETC96B2 withstands electrical transients common in heavy industrial facilities.

Key Features:

• Full-sized 96 × 96 mm (1/4 DIN) enclosure for industrial motor control centers and furnace panels.
• High-intensity 3-digit 0.8" White 7-segment LED display.
• Expanded dual-relay output: 2 × independent 10A @ 230V AC C/O relays.
• Dedicated 12V DC SSR voltage pulse output for zero-cross switching.
• Universal sensor input: J (0–600°C), K (0–999°C), Pt100 (-99–400°C), Pt.1 (-19.9–99.9°C).
• Auto-tuning PID, ON-OFF, and Time Proportional (TP) modes.
• 6 programmable alarm modes with delay timers ($dLtM$) and hysteresis settings.
