These are used when 2-wire transmitters are used in the field. They provide cost savings since they do not need to be purchased separately. 24 V (21.6–28.0 VDC, 30 mA MAX) sensor power supplies can be specified with the following models: UT551,...
This is a function in which output occurs a specified time after an alarm set point is exceeded. If you clear the alarm point during operation of the timer, the timer is reset.
This function supplies power to 2-wire transmitters. It differs depending on the specifications of the transmitter, but the input accepts 100 Ω resistors.
100 Ω resistor (model: X010-100-2, sold seperately)
Ladder communication is used when communicating with the Computer link unit/Serial communication unit. Modbus/RTU is used for communication with the Modbus communication module.
The common for all GREEN series alarm relay outputs are shared. In the UTAdvanced series, each alarm relay output has its own common. If used the same way, use external wiring to connect common to common.
Program changes for reading PV and OUT, writing SP, and other basic parameters are not necessary. There are registers and relays that support the GREEN series. For details see the UTAdvanced series communication interface (RS-485, Ethernet) user'...
Yes. This requires an RS-485/Ethernet converter such as VJET. The controller must also have a communication option. Some models can be connected directly with the UTAdvanced series.
The PV value can be written by using the ladder sequence function of UTAdvanced series. However, when communication is interrupted, the PV value is retained.
Check whether the wiring to the power supply terminal is correct. If only the LCD on the UT/UP700 does not display, a custom computation may be set for no display. If the PV display is also blank, this may indicate product failure. Please contact you...
PCBs (polychlorinated biphenyl) were banned from manufacturing and imports in 1975. The GREEN series began to be manufactured in 1997, and do not include PCBs.
For energize alarms, ON contact results when an alarm occurs. For de-energize alarms, OFF contact results when an alarm occurs. Note that OFF contact also results when the power fails.
