The EL.CO. ELK 22 S is a microprocessor-based digital temperature controller optimized for panel integration in demanding industrial environments. The patented design allows mounting in standard 48x48 mm cutouts or 22 mm circular holes, simplifying OEM machinery retrofits. With its detachable front module and IP64-rated front panel, it is suited for applications where limited budgets cannot tolerate sensor mismatch or manual PID tuning.

Why Choose the ELK 22 S

• Patented 22mm Mounting: The M22 neck allows installation directly in a 22 mm panel hole—eliminating the need for panel adapters and reducing OEM prototyping costs. (Source: handelsen [10†L12]; electronicsonline [6†L4-L5])
• IP64 Front Protection: Sealed against dust and low-pressure water jets. Ideal for environments like food processing, cold storage, and outdoor enclosures. (Source: DirectIndustry [5†L2])
• True Universal Input: Accepts thermocouples J/K and resistance probes Pt100/PTC/NTC without hardware modifications—lower spare parts inventory and rapid sensor replacement on site. (Source: electronicsonline [6†L10-L13])
• Autotuning PID with 100,000-Cycle Relays: One-touch autotuning calculates optimal PID parameters. Heavy-duty relays are rated for 100,000 operations at 250VAC, ensuring control stability and longevity in packaging machines and chillers. (Source: Nexus [12†L39-L41]; DirectIndustry [5†L6])
