ASCON TEMPERATURE CONTROLLER TLK49 & TLK48 SERIES

ASCON Tecnologic’s TLK49 and TLK48 series are high‑precision, single‑loop digital temperature controllers designed for industrial process control. The lineup includes TLK49 and six TLK48 variants: TLK48‑HCOR, TLK48‑HCRR, TLK48‑LCRR, TLK48‑LCOR, TLK48‑FCOR, TLK48‑FCR. Compact (48×48 mm, 1/16 DIN) and panel‑mountable, they deliver reliable PID/ON‑OFF control across heating, ventilation, and manufacturing applications.

Core Features

  • Universal Inputs: Accept thermocouples (J/K/S/R/T), RTD (Pt100), PTC/NTC, and voltage/current signals (0–10 V, 4–20 mA) for maximum sensor flexibility.
  • Advanced Control Algorithms: Equipped with auto‑tuning, self‑tuning, and fuzzy overshoot suppression; dual‑degree‑of‑freedom PID optimizes disturbance rejection and setpoint tracking.
  • Multiple Output Configurations: Up to 3 relay outputs (SPST‑NO, 8 A/250 VAC) or SSR drive (8 mA/8 VDC); model suffixes (HCOR/HCRR/LCRR/LCOR/FCOR/FCR) denote specific output combinations for heating/cooling and alarm functions.
  • Dual 4‑Digit LED Displays: Simultaneously show process value (red) and setpoint (green); 3 LED status indicators for outputs and alarms.
  • Flexible Power Supply: 24 VAC/DC or 100–240 VAC (±10%) for global compatibility.
  • High Accuracy: ±0.5% of span ±1 digit (25 °C); robust design for 0–50 °C operation.

Model Differentiation

  • TLK49: Dual‑display controller with 8‑segment programmer, independent timer, and TTL port; ideal for complex thermal cycles.
  • TLK48 Series: Single‑display, cost‑effective variants tailored to basic and mid‑range control needs.
    • HCOR/LCOR/FCOR: Relay + SSR output combinations for heating/cooling.
    • HCRR/LCRR/FCR: Dual relay outputs for heating/cooling or alarm interlocks.
