Temperature controllers

Direct current powered heaters of class III are providing a high safety standard but require on the other side high currents to be powered. Our powerful 12...48 VDC L-200 controller series are the perfect solution to power low voltage applications up to 20 ampere Due to the mostly harsh environmental conditions e.g. in utility vehicles, our L-200 series is encapsulated in resin against vibrations, dust and water. On top, the signal output gives you the feedback, if your application is keeping the right temperature.

Our robust L-300 and L-400 in-line controller series are perfectly tailored for the use with mobile applications. Stand-alone, waterproof and an intuitive operation are defining these user-friendlycontrollers. Factory set individual temperature ranges, setpoint, monitor function or integrated OEM-features make these controllers a perfect solution for your application.

• Simple detection of the actual status via LED status display.
• Setpoint can only be adjusted with IR control unit (L-200 and L-300 series).
• Robust aluminum housing (L-200 and L-300 series).
• Impact-resistant polycarbonate housing (L-400 series).
• Compact and robust temperature controllers for flexible applications.
• Flexible: 1 sensor input configurable for common RTD and TC sensors.
• Safety: setpoint can only be changed via IR control unit.
• Precise: high control quality and wear-free thanks to electronic switch.

You can also use the IR handheld to change setpoints remotely. This can also be done safely with many controllers in the vicinity. It is also possible to change the setpoint retrospectively with the L-200/300 series. The mounting plate is used to attach the L-400 to the wall. It can be removed using the Velcro fastener and is therefore easy to use. For the L-200/300 series, there is a clip that can be attached directly to a heating hose.

The robust multi-channel controllers are used wherever space is limited. Equipped with the same technology as the single-channel controllers, these controllers also stand for high durability. With the multi-channel solution, the installation costs can be reduced even further, especially with many heating circuits.

FAT stands for Fast Adaptive Tuning and describes the reliable algorithm – comparable to PID – that works in our controllers. A major advantage of FAT is the permanently self-optimizing controller adjustment without the need to adapt the PID parameters to changing ambient conditions. It is also not necessary to optimize the parameters during commissioning.

With a simple four-channel controller and the two-channel controller with dualSensor technology, Winkler offers cost-efficient options for controlling multiple heating circuits.

You can also use the IR handheld to change setpoints remotely. This can also be done safely with many controllers in the vicinity. In addition to remote operation, you ensure that the setpoints can only be adjusted by authorized persons.

The controllers specially developed for demanding laboratory applications are the perfect partner for our Pilz laboratory heating mantles. With either a thermocouple or resistance sensor, the temperature can be measured directly in the medium and thus a very precise temperature accuracy can be achieved. The robust table-top housing enables simple and reliable operation in the laboratory.

T-500 provides temperature control of the heating mantle using the built-in heating mantle sensor or alternatively via medium sensor. Using the heating mantle sensor prevents the temperature of the glass flask from becoming too high and from overheating at the edges of the flask . Alternatively, the medium sensor can provide a more exact temperature of the medium inside the flask. The T-500 series offers two models.

✅ T-560 for direct connection to Pilz Heating Mantles. 3+PE socket that perfectly matches the pin wiring of PILZ heating mantles plug connection. Either the heating mantle sensor or medium sensor can be connected. Delivery includes miniature plug for connection of the sensor. The connection cable for power supply is already included with the heating mantle or can be ordered separately.

✅ T-570 for Schuko socket for connection of other products that do not have or use integraged Winkler standard 3+PE plugs or 6+PE sockets. For example, Winkler heating tapes and cables with Schuko plug or heating mantles from other manufacturers. Other sockets enable the simultaneaous use of two sensors. Delivery includes Schuko plug with cold appliance plug C14 and miniature plug for connection of the sensor.

T-700 combines both advantages of control with two sensors. The medium temperature is regulated with high precision using the medium sensor. An additional sensor in the heating mantle is used to limit the temperature of the heating mantle during heating. This prevents the temperature of the glass flask from becoming too high and the medium from overheating on the inner flask surface. In addition, the T-700 allows advanced functions such as slow heating via ramp temperature settings. The T-500 series offers three models.

✅ T-760 for direct connection to Pilz Heating Mantles. 3+PE socket that perfectly matches the pin wiring of PILZ heating mantles plug connection. Other sockets enable the simultaneous use of two sensors. Delivery includes miniature plug for connection of the sensor. Delivery does not include connection cable for power supply. This is already included with the heating mantle or can be ordered separately.

✅ T-770 for use with a variety of heating products that have a Schuko plug. Schuko socket for connection of other products that do not have or use intergraded Winkler standard 3+PE plugs or 6+PE sockets.For example Winkler heating tapes and cables with Schuko plug or heating mantles from other manufacturers. Other sockets enable the simultaneous use of two sensors. Delivery includes Schuko plug with cold appliance plug C14 and miniature plug for connection of the sensor.

✅ T-730 fordirect connection to other Winkler products with combined power and sensor coupling. 6+PE plug for connection of other heating products with 6+PE sockets. For example, Winkler heating mats and jackets using two sensors at the same time. Delivery includes miniature plug for connection of the sensor. Delivery does not include connection cable for power supply.This is already included with the heating mantle or can be ordered separately.
