High-Accuracy Controllers with Universal Input and Output Functions
The UT320 and UT350 controllers are digital indicating controllers which feature universal input and output. The user can set or change the type of measured inputs, the measurement range, and the type of output. A three-point alarm is standard, a heater disconnection alarm is optional. Autotuning and a super overshoot function are available as control functions, and a retransmission of variables or a loop power supply for a transmitter are also included as standard features.
A four-digit, large LED display makes readings clearly visible from considerable distances.
