The WEST CS' KS Vario T4 series multi-loop Controllers are mostly used in scientific thermal treatment or similar industrial applications. They have a modular design, and offer individual control for up to 30 temperature zones. They contain a bus coupler, control unit and I/O modules in different sizes (2, 4, 8, or 16 channels), that are inter-connected from start, without the need to manually connect. The modular design also promotes cost-effectiveness, and offers compatibility with different systems. The controllers can also be used for Ethernet, Profibus DP, CANopen, DeviceNet, and Modbus, offering usability for a wide range of industrial applications and processes.
