W-234 W-334 W-432 Temperature multichannel controllers for line integration

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.

W-234 DC 4-channel controller for wall mounting without operation panel. Only with the IR-Handheld you can change setpoints. This can be done safely even with many controllers around.

• Compact: 4 channels in a compact housing for optimum space saving.
• Flexible: 1 sensor input per channel configurable for common RTD and TC sensors.
• Precise: high control quality and wear-free thanks to electronic switch.
• Safety: setpoint can only be changed via IR control unit.
