Process Dual Indicator
DMY-2011 Process Dual Indicators.
DMY-2035 Process Dual Indicators.
The design of DMY-2011 and DMY-2035 Process Dual Indicators is characterized by high reliability and precision, electrical noise and EMI immunity, besides well elaborated technical manual.
These features make them ideal for industrial applications in Instrumentation and Process Control.
They have an extruded aluminum case and use the best origin components and parts, proven by rigorous tests and specified according to the strictest worldwide norms.
They offer two standard universal inputs that can be 4-20mA, 1-5Vdc, 0-10Vdc, 0-55mVdc, thermocouples and RTD; also standard is the 24Vdc power supply for two-wire transmitter.
This way, you can use an input to measure flow through a two-wire transmitter and other input to measure temperature through thermocouples or RTDs.
Two frequency inputs are available, in specific instrument, for signals up to 30kHz, from 300mVpp to 30Vpp and 70Vdc max. DIN 19234 compliance for intrinsically safe NAMUR sensors.
