In-panel Temperature Controller with Flexible,
Modular Design and Wide Integration with Host,
Devices.
The compact modular structure enables construction of temperature,
systems optimally suited to the application.
Connection can be made to a Programmable Controller without any,
programming required, reducing the number of steps required in ladder,
programming design.
One fully universal-input Unit includes a thermocouple, platinum-resistance,
thermometer, and analog input for easy selection and reduced inventory,
requirements.
Conneect directly to tthe G3ZA Multi-channel Power Controller using,
optimum cycle control for high-accuracy regulation with minimal noise K3NR-NB1A-L4.
Autotuning (AT) can be used for independent heating/cooling PID control.
Self-tuning (ST) can be used to calcullatte the PID constants with the step,
response method K3NR-NB1A-L4.
Up to 16 Temperature Controllers can be connected to a single DeviceNet,
Communications Unit.
