Yokogawa Manual Setter UD320-00
General
Yokogawa Manual Setter UD320-00
The UD300 series manual setters have PV display, and transmit 4 to 20mA DC by manual operation. It can be
used as a remote setter for digital indicating controllers like
GREEN series controllers.
The SP (target setpoint) will be output in 3 seconds after the change.
The TC, RTD or Voltage input is possible as PV input. When the PV display is not necessary, it can be disap- peared.
The two alarm outputs and a PV retransmission output are provided as standard.
The front panel has a splash-proof and dust-proof design
(IP65), which enables the use in the dusty environment.
