The Autonics TK4S-R4SR Temperature Controller is engineered for high-speed and accurate thermal regulation, powered by a universal 100β240VAC~ 50/60Hz supply. With a sampling cycle of 50ms, it ensures rapid and consistent temperature adjustments. It supports a wide array of input signals including thermocouples (K, J, T, R, S, B, etc.), RTDs such as Pt100 and JPt100, and analog inputs ranging from 0β100mV to 4β20mA. This broad input compatibility makes it suitable for multiple industrial setups, including legacy and modern systems.
The controller offers advanced P, PI, PD, and PID control methods, along with manual reset and adjustable hysteresis for fine-tuned process control. It features dual control outputs β an SSR drive (11VDC) and a relay output (250VAC 3A) β enabling integration into various load circuits. The IP65-rated front panel ensures protection against dust and water, while its double insulation and 2kV dielectric strength deliver electrical safety in harsh industrial environments. Precision is further supported with display accuracy of Β±0.3% at room temperature across CT, RTD, thermocouple, and analog signals. Despite these robust specifications, the unit remains compact and lightweight at approximately 150g, allowing for efficient panel space utilization and installation flexibility.
