Silicontra GC433-TX043

The GC433-TX043 wireless temperature measurement module integrates RF circuitry with a CT power-harvesting circuit, purpose-built for power industry applications. It features ultra-low startup current CT power harvesting with a minimum startup current of 3A, and employs LoRa wireless modulation technology for superior interference immunity and signal penetration. Combined with the compact and precise characteristics of temperature sensors, users can deploy the module quickly with minimal parameter configuration. The module delivers ±1℃ temperature measurement accuracy, offering high precision in a small form factor, making it suitable for most power industry temperature monitoring scenarios. Its dimensions are designed to fit standard market enclosures — users simply configure the module, insert it into the housing, and it is ready to use, eliminating tooling costs for non-standard enclosures. Parameters are configured via serial communication; the company provides a convenient PC configuration tool and command format, supporting settings such as frequency channel, output power, temperature transmission interval, and baud rate, with automatic parameter saving that persists through power loss.
