DESCRIPTION

· The CT48A (Part number 89420047) is a temperature controller designed for precise regulation in various applications.

· It supports input from J-K thermocouple or Pt 100 thermoresistance (2-wire configuration).

· The device offers two regulation modes: ON/OFF or proportional derivative, selectable via wiring.

· It features a relay output for control operations.

FEATURES

· Supply voltage range: 230 to 240 VAC at 50/60 Hz, with an operating range of 0.85 to 1.15 x Un.

· Maximum power consumption: 2 VA.

· Automatic cold-junction compensation for J-K thermocouple.

· Maximum line resistance: 150 Ω; derating of 1°C per 0.4 Ω increase in line resistance.

· Changeover relay rated at 5 A / 250 V AC max, with a mechanical life of 3x10^5 operations.

· Display accuracy: ±2% for J-K, ±1.5% for Pt 100.

· Operating temperature range: 0°C to +55°C; storage temperature range: -20°C to +70°C.

· Protection class: IP20 for casing, IP41 for front panel.

APPLICATIONS

· Suitable for environments requiring precise temperature control, such as industrial processes, HVAC systems, and laboratory equipment.

· Ideal for applications where reliability and accuracy in temperature regulation are critical.

· Can be used in systems that require both ON/OFF and proportional control strategies.
