Detailed Product Description

TF13 is a stand-alone electronic universal controller with two autonomous control loops. Each control loop may use up to 2 PI sequences and 4 binary sequences. The controller features 1 NTC temperature sensor input and 1 analog input. Each input is assigned to a specific control loop.

The controller features 2 binary outputs (TRIAC) and one analog output. The outputs need to be assigned to the control sequences by software. A detailed parameterization is possible with the use of a simple configuration routine. The controller can be configured using the standard operation terminal. No special tools or software is required
