Product Description

The KT28-31R thermostat is a versatile component of the KT28 series thermal switch family, designed as an adjustable temperature protector switch with a broad temperature range of -20°C to +120°C. It features a compact 2.4-inch LCD display for real-time monitoring and supports 2 analog inputs and 1 relay output, enabling direct integration with up to 3 modular expansion units. Operating on 12-24V DC, this switch is compatible with RS-485 communication interfaces for seamless industrial automation connectivity. Ideal for HVAC systems, manufacturing machinery, and energy management applications, it offers ±1°C precision for reliable thermal protection. The device operates reliably within -30°C to +70°C ambient conditions and includes a 2000mAh backup battery. Its primary limitation is reduced sensitivity in environments with rapid temperature fluctuations exceeding 10°C/s. With an IP65-rated enclosure and 5-meter sensor detection range, it balances durability and functional adaptability.
