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.

Many optional modules are available:
Up to two analog output modules of 4-20mA, 1-5Vdc and 0-10Vdc.
Up to four SPDT and SPST relay alarm modules.
Water-proof front-panel.
Two universal standard inputs for RTD, thermocouples, 0-55mV, 4-20mA, 1-5Vdc and 0-10Vdc. Available specific models for two frequency input signals up to 30kHz, from 300mVpp to 30Vpp.
Indicate 2 variables simultaneously.
Their robust construction make them tough enough for the most hostile environment.
Power supply from 90 to 240Vac, 50/60Hz or dc levels.
High accuracy.
Linearization of RTD, thermocouple and also square root extraction.
Fully configurable by front-panel push-buttons.
ACK button.
Configuration stored in non-volatile memory.

Power supply is universal and can be connected from 90 to 240Vac or dc levels when specified. Flexibility and modularity concepts are clear due to the variety of modules available meeting the widest applications.
Up to four alarm modules.
One or two analog output of 4-20mA, 1-5Vdc or 0-10Vdc.
Serial communication and digital input-output.

Inputs
Universal inputs models for thermocouple (J, K, T, E, R or S under ITS-90), 0-55mV, RTD under
DIN 43760, 4-20mA, 1-5Vdc and 0-10Vdc selected by user. Input impedance of 250 ohms for mA, 10 M ohms for 5Vdc and 2 M ohms above 5Vdc. Frequency inputs models for signals up to 30kHz, from 300mVpp to 30Vpp and 70Vdc max. DIN 19234 compliance for intrinsically safe NAMUR sensors. Note: Universal or frequency inputs require different instruments. See order code.
Outputs
4-20mA (750 ohms maximum load), 1-5Vdc or 0-10Vdc analog retransmitter.
Up to two optional modules galvanically isolated to 300Vac from power supply and inputs.
Up to four SPST and SPDT relays rated for 3A at 220Vac. Logic signal, open collector transistor, 40mA/24Vdc maximum with isolation. Note:
There are 4 fitting connectors internally, so, the total number of optional output modules is 4.
See order code.
Serial Communication RS-232 or RS-422/485 with 50Vdc isolation.
