General Specifications GS 0F01D0E Model UM1 Digital Indicator with Alarms with Active Color PV Display General Model UM1 Digital Indicator with Alarms is a precision 1/8 DIN alarm instrument provided with universal input. For excellent monitoring operability, it has a large PV display with the PV display color changing function Active Color PV Display. It is provided with four alarm setting points or setting outputs (one is optional function). A retransmission output and 1 V DC loop power supply are also provided as standard. A communication function and V DC loop power supply are available optionally. Main Features Extralarge digital display allows the indicated values to be read even from a long distance. LEDs of 0 mm height are used for the PV display. The PV display color changing function "Active Color PV Display" is provided. PV display color is changed from green to red and vice versa when an alarm occurs. The color also can be fixed in green or red. Universal input allows simple setting of the input type (thermocouple, RTD or mv) and range from the front panel. Various communication functions are provided. Communication is possible with personal computer, programmable logic controller, and other instruments.
