Name: PYST1H0555 Digital Temperature Controller
SKU: PYST1H0555
Availability: InStock

Overview

This PYST1H0555, microprocessor-driven digital temperature controller is engineered for precise climate regulation in refrigeration, HVAC, and commercial/industrial applications. Operating on a standard 230VAC power supply, it features a panel-mount form factor with plug-in screw terminals for quick, secure installation. It supports dual NTC temperature probes and auxiliary inputs, enabling accurate monitoring and control of cooling cycles, defrost operations, and system alarms, while its high-reliability relay outputs are rated to handle typical compressor and auxiliary equipment loads.

Key Features

Precision Temperature Control: Supports dual NTC probe inputs for accurate ambient and evaporator temperature monitoring, with configurable setpoints for cooling and defrost operations.
230VAC Power Supply: Built for direct mains operation, eliminating the need for external transformers in standard 230V environments.
High-Capacity Relay Outputs: Rated for up to 12A FLA / 72A LRA (250Vac), capable of directly driving refrigeration compressors and auxiliary loads.
User-Friendly Interface: Integrated buzzer alarm and status indicators provide immediate visual/audio feedback for system conditions and faults.
Compact DIN-Rail Design: 71×29mm form factor fits standard panel cutouts, with plug-in screw terminals for fast, secure wiring.
Certified Reliability: Compliant with CE and UL safety standards, built for long-term performance in demanding operating conditions.
Versatile Functionality: Includes auxiliary input and configurable operating modes for refrigeration cabinets, cold rooms, and HVAC systems.
