The Autonics TK4L-R2RR operates on a flexible power supply of 24VAC~ 50/60Hz or 24–48VDC, making it compatible with both AC and DC systems in industrial setups. With a sampling cycle of 50ms, it offers fast and accurate temperature monitoring. This controller supports multiple input types including thermocouples, RTDs like Pt100Ω, and analog signals such as 4–20mA, giving engineers versatile integration options. It delivers reliable PID, PI, PD, P, and ON/OFF control modes, and outputs include dual relay outputs (250VAC~ 3A) and transmission output (DC 4–20mA) for smooth actuator compatibility. The 4-digit 7-segment LED display ensures clear visibility of process variables and parameters during configuration or operation.
Durability and precision go hand-in-hand with the TK4L-R2RR PID Controller. It maintains ±0.3% F.S. display accuracy at normal ambient conditions and is housed in a design that supports IP65 front panel protection. Built-in electrical safety features like double insulation and 2kV dielectric strength between input and power components make it suitable for rugged usage. Engineers can confidently deploy it in temperatures ranging from -10°C to 50°C with up to 85% RH humidity. The compact build, weighing only approx. 294g, allows easy DIN panel mounting. Optional inputs like CT and digital signals plus RS485 communication expand its usability in networked control systems.
The Autonics TK4L-R2RR Temperature Controller is used in precise temperature regulation across a variety of applications such as plastic molding machines, packaging systems, drying ovens, sterilization units, and HVAC systems. Its high-speed response, dual output channels, and multi-signal support make it a go-to solution in sectors like food processing, pharmaceuticals, electronics, and industrial machinery.
