Series UT
Electronic Indicating Controls
Series UT Yokogawa electronic controls are available in 1/4 and 1/8 DIN sizes. Red LED displays show both process and
set point.
The UT can accept inputs from all thermocouples, RTDs, mV and mA. Outputs can be relay, pulse DC for solid state
relays and 4 - 20 mA for step controls and SCRs. Most controls are field configurable to any input and output.
